Natural Gas Liquids (NGLs) in North America: An Update 1 Part I - Upstream Introduction This report is part of an update to CERI Study No. 130: Natural Gas Liquids (NGLs) in North America: Overview and Outlook to 2035, published in the summer of 20121 (the NGLs study). Given the high level of interest from various audiences, CERI has undertaken the task to update its NGLs overview and outlook by incorporating and considering various issues and trends that have developed since Study No. 130 was first published. Furthermore, given the importance of natural gas supply and demand dynamics in the outlook for NGLs, CERI is incorporating four natural gas scenarios developed over the last year and outlined in a recently published CERI report: Study No. 138: North American Natural Gas Pathways.2 This is the first of five parts (or reports) that make up the NGL update. Parts I-III will focus on a discussion of historical data (2002 to 2012) as well as currently evolving trends that are shaping NGL markets in both Canada and the United States (US).3 This report (Part I) will provide context in regards to production of NGLs from different sources (upstream), Part II discusses existing and evolving NGL infrastructure and NGL end-users (midstream and downstream), while Part III discusses supply and demand (S/D) balances for each NGL, as well as pricing and economics. These reports will be complemented with a discussion of what CERI believes to be some of the most relevant issues currently transforming NGL markets. The first section of each report will focus on Canada while the second chapter will focus on the US, with a Canadian-focused analysis presented in the final section of each report. Given the increased importance of global energy markets and continued demand increases in the Asia-Pacific region, Part IV will discuss NGLs in the global context as well as opportunities and challenges for Canadian NGLs/petrochemicals in global markets and the importance of the Asia-Pacific region as a target market. Part V will use the insights from this overview and emerging trends analysis (Parts I-IV) in order to develop an outlook for NGLs in North America based on the four natural gas scenarios. A discussion of the outlook methodology will be presented in that report, and each NGL will be discussed in the context of a supply and demand balance outlook based on the different scenarios. Lastly, Part V will include a discussion on what the different outlook scenarios mean for different industries that rely on NGLs in terms of opportunities, challenges, and possible future prospects. The scenario-based approach has been chosen as it allows CERI to consider a range of possibilities in the context of NGLs availability and demand in a long-term timeframe. 1 Available at: http://ceri.ca/images/stories/2012-08-21_CERI_Study_130_NGLs_In_North_America.pdf 2 Available at: http://ceri.ca/images/stories/2013-09-05_CERI_Study_No__138_-_North_American_Natural_Gas_Pathways.pdf 3 With a more in-depth focus on Canada May 2014
2 Canadian Energy Research Institute This is in contrast to a base case scenario (Study No. 130) whereby results were given around a general set of assumptions and where there were possibilities of significant downside or upside revisions on the results given the sensitivity of certain key variables. The scenario-based approach thus allows for a broader examination of possible outcomes. While Study No. 130 was an introduction to NGLs in North America and served the purpose of generating awareness on the importance of NGLs within the context of the energy industry in North America, this report assumes a certain level of understanding of NGL markets and will focus on more specific issues.

Natural Gas Liquids (NGLs) in North America: An Update 3 Part I - Upstream Executive Summary Canada is one of the world’s largest producers of natural gas liquids (NGLs),4 with output originating primarily at gas processing plants, but also crude oil refineries, oil sands upgrader off-gas processing plants, and at the field level as field or wellhead condensate. Between 2002 and 2012, total NGL production levels in Canada fluctuated with peak levels reached at close to 760 thousand barrels per day (kb/d) in 2007, ensued by a declining trend and a trough of 657 kb/d in 2010, a point from which production levels have turned around to reach close to 680 kb/d by 2012. While production of NGLs from natural gas plants5 accounted for 91 percent of total Canadian NGL production in 2012, declining volumes of liquefied petroleum gases (LPG) 6 from refineries, due to a combination of refinery closures and changes in the crude slate, have contributed to overall NGLs declining volumes. Meanwhile, production of synthetic gas liquids (SGLs)7 from off- gas processing plants has increased rapidly, driven by strong oil sands activity and synthetic crude oil production (SCO), not only supporting overall NGL production levels, but also providing an alternative source of NGLs and large potential for further future growth in NGLs extraction volumes. Refineries accounted for 7 percent of Canada’s NGL production in 2012 while off-gas plants accounted for 2 percent. Gas plants’ NGL production comes primarily from Western Canadian provinces with almost all extraction occurring in Alberta (AB) (90 percent of gas plants’ NGLs) and British Columbia (BC) (9 percent), where ethane and propane (combined) accounted for about 2/3 of the gas plant NGL barrel in 2012. Given the significance of gas plants’ NGL production, an understanding of issues affecting natural gas production volumes in these provinces is the foundation of understanding factors that will affect NGLs production in years to come. In the United States (US), overall NGL production levels (from gas plants and refineries combined) were on a flat to declining trend until around 2008 (2,414 kb/d) from which point extraction of NGLs from gas plants accelerated rapidly and led to total NGL production levels of over 3,000 kb/d by 2012. Increased production of gas plants’ NGLs in the US has in turn been the result of rapid increases in natural gas production volumes from unconventional sources (including shale, tight, and coalbed methane formations) led by process innovation around production (such as horizontal drilling and hydraulic fracturing), but also due to underlying commodity pricing conditions that have favoured extraction of NGL-rich or wet gas. Production of NGLs from gas plants accounted for 80 percent of total US NGL production in 2012. 4 Includes ethane (C2H6), propane (C3H8), butanes (n-C4H10 and i-C4H10), and pentanes plus/condensate (C5+) 5 Includes field plants, straddle plants, fractionators, and field condensate 6 Propane and butanes 7 Mix of paraffinic (NGLs) and olefinic (ethylene, propylene, butylene, and olefinic condensate) hydrocarbons May 2014
4 Canadian Energy Research Institute Given the US’ role as Canada’s main trading partner in goods and services, but more importantly, energy commodities; increasing natural gas production volumes unmatched by equivalent demand increases in the US has meant that import requirements continue to decrease. While US demand for gas has increased, primarily in the power generation sector, supply increases have far outpaced demand increases, displacing costly overseas liquefied natural gas (LNG) imports first, followed by Canadian gas in various traditional markets including the US Upper Midwest and US Northeast markets. Furthermore, Eastern Canadian markets which were traditionally served by Western Canada’s gas, are increasingly meeting their own needs by acquiring closer US-sourced gas. In Canada, gas demand has increased, driven by increases in the power generation and industrial sectors (including oil sands), but demand increases have not been large enough to compensate for increasing US imports and lost US export volumes, leading WCSB producers to scale back on production activities and to look for alternative markets both domestically and abroad (as LNG). These changes in market fundamentals point to a rapidly evolving natural gas market in North America and a re-organization of flow patterns from producing areas to market centers. While various economic factors have also affected WCSB producers including volatile prices, currency exchange rate fluctuations, and increasing transportation tolls (amongst others), supply cost efficiencies and monetization of NGLs have become important components of WCSB producers profitability and competitiveness strategies in the North American market. This has led to a unique situation in the upstream context of Canadian NGLs whereby overall gas production levels have continued to decline while NGL production volumes are recovering, increasing rapidly, and expected to continue to do so over the long-term. Going forward, understanding the demand for Canadian gas across North America and possibly in the global market (as LNG), as well as natural gas prices, the composition of the gas, and the focus of producers’ on given areas of the WCSB, will help in shaping the expected volumes of NGLs available for extraction in the WCSB. NGL availability will be the foundation for different NGL outlook scenarios that will be presented in Part V of the NGLs study update. But understanding changes in natural gas markets and NGL availability needs to be complemented by an understanding of NGL infrastructure; NGL markets supply, demand, pricing, and economics (market fundamentals), but also an understanding of global NGL markets. These subjects are discussed in Parts II – IV of the NGLs update. May 2014
Natural Gas Liquids (NGLs) in North America: An Update 5 Part I - Upstream Canadian Natural Gas Liquids (NGLs) Production (2002-2012) It is important to clarify from the onset that within the Canadian context, the definition of natural gas liquids (NGLs) includes hydrocarbon liquids recovered from the raw natural gas stream at gas processing plants,8 liquefied petroleum gases (LPGs) from crude oil refining,9 synthetic gas liquids (SGLs) recovered from oil sands upgrader off-gases, and liquids recovered at the wellhead level such as field condensate (as seen on Figure 1.1). These, in turn, include ethane (C2H6, or C2), propane (C3H8, or C3), butanes (normal (n-C4H10) and iso-butane (i-C4H10), (or C4s), as well as pentanes plus10 (pentanes plus and condensate) (C5+). Figure 1.1: Sources of Natural Gas Liquids (NGLs) in Canada Natural Gas, Crude Oil, and Crude Bitumen Refinery Liquefied Upgrader Synthetic Gas Processing Petroleum Gases Wellhead or Field Gas Liquids (SGLs) Plant Liquids (LPGs) Condensate (C5+) (C2, C3, C4s, C5+) (NGLs/Olefins Mix) (Primarily C3, C4s) Source: CERI Canada is one of the world’s largest producers of NGLs,11 yet between 2002 and 2012 production has fallen from a level of 765 thousand barrels per day (kb/d) to 677 kb/d, or by about 10 percent (-88 kb/d net). From the start of the 2002 to 2012 timeframe, production peaked at 765 kb/d followed by a decline trend and a second peak of 757 kb/d by 2007, after which a declining trend ensued. By 2010, a low of about 660 kb/d was observed. Over the last couple of years, that trend has reversed and production is once again increasing. As can be observed in Figure 1.2, the majority of natural gas liquids (around 91 percent in 2012) were produced at natural gas processing plants,12 while the remaining (nine percent or so) were produced at both refineries and upgraders (in that order).13 8 Including field plants, straddle plants, and fractionators but also field condensate 9 Mainly propane and butanes 10 Generally includes pentanes, hexanes, and heptanes 11 See: International Energy Agency (IEA), Natural Gas Liquids, Supply Outlook 2008 – 2015, April 2010: http://www.iea.org/Textbase/npsum/NGL2010SUM.pdf Oil & Gas Journal (OGJ), Rapid North American shale gas development pushes up global capacities: http://www.ogj.com/articles/print/volume-111/issue-6/special-report--worldwide-gas-processing/rapid-north-american-shale- gas-development.html 12 Includes field condensates, as well as NGLs produced at field plants, straddle plants, and fractionators May 2014

Figures by CERI To understand these trends, it is important to discuss each source of NGL production as well as the respective driving forces behind these trends. Gas Plant NGL Production Production of NGLs from natural gas processing plants depends on a series of factors that are intrinsically tied to trends in natural gas production. These include (but are not limited to) the type of gas reserves being developed and their respective composition, which in turn dictates the amount of liquids available in the gas being produced; the amount (volumes) of gas being produced and processed; the efficiency of gas processing plants to recover the liquids in the raw gas; and the demand and markets for each liquid. These will be further elaborated upon in the analysis section. Figure 1.3 illustrates the production of NGLs from natural gas processing plants. 13 On a percentage basis by NGL, in 2012 ethane accounted for 32% of the total 681 kb/d of NGLs production, followed by propane (31%), pentanes plus (21%), and butanes (16%) 14 Alberta Energy Regulator (AER): Data & Publications, Statistical Reports (ST): ST3: Alberta Energy Resources Industries Monthly Statistics; ST39: Alberta Mineable Oil Sands Plant Statistics Monthly Supplement; ST98: Alberta’s Energy Reserves & Supply/Demand Outlook.

Figures by CERI As can be observed, NGL production from natural gas processing plants follows the same trend that total NGL production exhibits. Given the large share of gas plant production of NGLs (>90 percent), it could be suggested that production from gas plant NGLs is the main driver behind the overall NGL production trend. However, the rate of decline in NGL production from gas plants over the 2002 to 2012 timeframe has been lower than the overall decline (-81 kb/d) suggesting it has not been the only cause for the overall NGL production decreasing trend. It can also be observed that light NGLs (C2 & C3) accounted for 65 percent of the total NGLs produced at gas plants in 2012 compared to 35 percent for the heavier ends (C4s & C5+). These percentages were consistent through the decade, and are also similar to percentages for overall Canadian NGL production. Figure 1.4 illustrates production of gas plants’ NGLs by province in the same timeframe,18 together with their respective shares for 2012. As can be observed, Alberta (AB) and British Columbia (BC) together accounted for 99 percent of NGL production from natural gas processing plants. While not readily apparent, one underlying trend in Figure 1.4 is that the main declines in NGL production from gas plants have occurred in AB and Nova Scotia (NS), while BC NGL production volumes remained relatively flat until 2010 at which point they started to increase rapidly. This is consistent with natural gas production trends in these respective areas. 18 Unless otherwise noted, the analysis presented in Parts I-IV are discussed in the 2002 to 2012 timeframe May 2014

Figures by CERI The main takeaway in regards to NGL production from gas processing plants is that the overall level of NGL production is largely (but not solely) affected by production of NGLs from gas plants, where ethane and propane are the largest components of the NGL barrel (about 2/3), and whereby regionally, BC and AB account for almost all the production of gas plant NGLs. Refinery LPG Production LPGs are a minor portion of the output from crude oil refineries as seen in Figure 1.5.

Figures by CERI. 19 The difference between crude runs and RPPs production is due to volumetric gains as RPPs tend to be lighter than the crude oil from which they are produced May 2014
Natural Gas Liquids (NGLs) in North America: An Update 9 Part I - Upstream In 2012, propane and butanes, together, accounted for only three percent of total refined petroleum products (RPPs) from Canadian refineries. Meanwhile, motor gasoline, diesel fuel, as well as heavy and light fuel oils, combined, accounted for 75 percent of total output. Figure 1.5 also illustrates that production of RPPs has decreased from 2,051 kb/d in 2002 to 1,934 kb/d by 2012, or by six percent. While exports of RPPs have increased slightly over the same timeframe, so have imports (at a faster pace than exports), resulting in net exports of RPPs remaining flat to decreasing. Given a flat net export trend and lower overall production, this suggests that implied demand for RPPs in Canada (production + imports – exports) has decreased over the last decade.21 Lower demand for RPPs in turn results in a lower need for crude runs at Canadian refineries. As seen in Figure 1.6, production of LPGs from refineries has declined by 22 percent between 2002 and 2012 (-14 kb/d net), suggesting that declines in refinery LPG volumes are partly responsible for overall NGL production volume declines.

Figures by CERI Furthermore, Figure 1.7 shows that on a regional basis, refinery LPGs production has declined in regions like Ontario (ON), Alberta and Quebec (QC); remained steady in British Columbia and Saskatchewan (SK), and increased in Atlantic Canada (NFLD, NS, and NB). CERI has identified at least two factors that are believed to be responsible for this trend. In regards to Ontario and Quebec (Central Canada), refinery closures over the past decade at Oakville and Montreal, respectively, have resulted in less crude being processed in this region. Lower crude runs (see Figure 1.8) have in turn resulted in lower production of RPPs overall, and therefore, lower production of refinery LPGs in these areas of the country. With the future prospect of the Dartmouth, NS23 and Come by Chance, NFLD24 refineries possibly closing down over the next few years, this trend could continue to be observed in other areas of the country as well (mainly Atlantic Canada). On the other hand, the construction of a new upgrading refining/complex in AB 25 (and possibly BC26), as well as a gas-to-liquids (GTL) plant (Sasol), could offset some of those lost LPG volumes on the refining side of NGL production in Canada. 23 Imperial Oil, Media: Imperial Oil to Convert Dartmouth Refinery to Terminal: http://www.imperialoil.ca/Canada- English/about_media_releases_20130619.aspx 24 September 17, 2013: Calgary Herald: Update: Harvest refinery on block says report.

Figures by CERI Contrary to developments in Central Canada, a series of refinery expansions and modifications over the last decade have resulted in overall refining capacity increases in the Western (BC, AB, and SK) and Atlantic Canada regions. After accounting for closures in Central Canada and expansions as well as modifications/ expansions in Western and Atlantic Canada, overall Canadian refining capacity has actually increased by six percent from about 2,003 kb/d of capacity in 2002 to 2,130 kb/d by 2012. Meanwhile, the number of refineries has gone from 21 to 18 during the same timeframe.28 In both Western and Atlantic Canada, this has resulted in an overall increase in crude runs over the decade. However, this has not resulted in increases in refinery LPGs production in both regions. This suggests that in respect to refinery LPGs production, not only how much crude goes to the refinery matters, but also the type of crude. As seen in Figure 1.9, the crude slate (or diet) of refineries in these areas is rather different. In Western Canada, refineries process a variety of different crudes, yet as can be observed, the share of synthetic and heavy crudes processed has increased over time. 27 Table 07-03B: Refinery Crude Oil Capacity – Canada; Table 07-05A: Refinery Closures – Canada. Available at: http://www.capp.ca/library/statistics/handbook/pages/statisticalTables.aspx?sectionNo=7 28 Refineries closed over the last decade in Canada include those in Oakville, ON (2005); Montreal, QC (2010); and Bowden, AB (2012)(Total Capacity = 215 kb/d) May 2014

Figures by CERI In 2012, these types of crudes (combined) accounted for about 75 percent of the total crudes processed in the region compared to about 55 percent in 2002. This matters because both synthetic and heavy crudes have a lower volume percentage of light ends such as propane and butanes29 (LPGs). Thus, while overall crude runs have increased, refinery LPGs production in the (Western) region have decreased as a function of a change in the crude slate or diet. In Atlantic Canada, crude runs have increased, but the crude slate has also changed from about 90 percent light and 10 percent heavy in 2002, to almost 100 percent light by 2012. Therefore, a combination of increased crude runs and a switch to a lighter crude feedstock helps to explain the overall increase in refinery LPGs production in the Atlantic region. This increase, however, has not been large enough to offset decreases across other regions in Canada (both Western and Central Canada). Going forward, considering how RPPs demand could change in Canada, and how crude runs could change across the country based on refining capacity changes (closures, expansions/ modifications, or additions) as well as understanding the possible changes in crude slates, will determine the outlook for refinery LPGs production. Oil Sands Upgraders SGL Production Synthetic gas liquids (SGLs) are a mix of paraffinic30 and olefinic31 hydrocarbon liquids that are recovered from off-gases produced during the crude bitumen and heavy conventional crude upgrading and refining processes. 29 See: http://crudemonitor.ca/home.php; and, CERI’s Study No. 130: Natural Gas Liquids (NGLs) on North America: Overview and Outlook to 2035 30 Ethane, propane, butanes, and pentanes plus 31 Ethylene, propylene, butylene, and olefinic condensate May 2014
Natural Gas Liquids (NGLs) in North America: An Update 13 Part I - Upstream The upgrading process aims to produce a light synthetic (sweet or sour) crude oil (SCO) similar to conventional light crude. Once extracted, SGLs are further separated into their individual components just like NGL mixes, in order for the products to be transported and marketed. As can be observed in Figure 1.10, production of SCO in Western Canada has more than doubled between 2002 and 2012 (a 126 percent increase). In 2012, the largest share (68 percent) of SCO was produced at the integrated mining and upgrading projects in the Athabasca oil sands area (Suncor, Syncrude, and CNRL). Another 22 percent was produced in the AB Industrial Heartland (Fort Saskatchewan area, AOSP Scotford upgrader), even though the bitumen feedstock for this project comes primarily from mining projects in the Athabasca area. The remaining less than ten percent was produced from in-situ projects.32 Figure 1.10: Synthetic Crude Oil (SCO) Production in Western Canada by Project (L) and Area (R) (kb/d) (2002-2012) 1,200 OPTI/ Nexen - Long Lake 1,200 CNRL - Horizon Athabasca Area (In-situ) Husky - Lloydminster Lloydminster - Cold Lake Area (In-situ) 965 AB Industrial Heartland 965 1,000 Shell - Scotford 917 1,000 Athabasca Area (Mining) 917 Suncor - Base Mine 846 846 826 Total SCO Production 826 Syncrude - Mildred Lake 800 Total SCO Production 739 720 712 800 720 739 712 656 656 604 604 kb/d kb/d 600 600 495 495 428 428 400 400 200 200 - - 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 33 Source: Data from AER, AESRD, and Husky Energy. Figures by CERI Figure 1.11 displays production of off-gases34 by project and by area. A distinction is made in these charts between the total off-gases produced from all projects and the total excluding the OPTI/Nexen Long Lake project. The reason for this distinction is that this particular project was purposely designed to fully utilize its off-gases for both fuel and steam production for its in-situ steam assisted gravity drainage (SAGD) operations in order to reduce natural gas usage. 32 This is a simple generalization as Suncor’s upgrader processes in-situ volumes while the Scotford upgrader could potentially source feedstock from in-situ projects. Furthermore, the majority of the Lloydminster upgrader’s feedstock is conventional heavy crude from SK and AB as opposed to crude bitumen 33 Husky Energy, Investor Relations, Annual Reports & Fillings: Information retrieved from Annual Information Forms (AIF) from 2002 to 2012.

Figures by CERI This project is therefore using its off-gases in a closed loop system and the off-gases are not likely available for SGLs extraction. It is important to point out that the Long Lake project only accounted for about three percent of total SCO production in 2012, yet it produced about 30 percent of the total upgrader off-gases. Therefore, it is important to consider that the amount of off-gases produced by an upgrading operation will largely depend on the technology being used.36 As an example, CERI estimates that a coking upgrader such as those used in the Suncor, Syncrude, and CNRL operations produce between 0.4-0.6 thousand cubic feet (mcf) of off-gases per barrel of SCO produced, while the ratios for hydro-cracking (Shell) and OrCrude (OPTI/ Nexen) upgraders are 0.8 and 6.1, respectively. Furthermore, SGLs recovered from off-gas produced by coking upgraders (Suncor and CNRL) have a significant olefinic content and require segregation from the paraffinic NGLs produced by gas plants, and refineries; SGLs recovered from hydro-cracking upgraders (Shell)37 tend to contain a low to minimum olefinic content and be primarily composed of NGLs. 35 CERI estimates for the years 2002 – 2007 are based on analysis of SCO, off-gas, and SGLs production data from AER ST-39 and analysis conducted by CERI and presented in Study No. 130. Off-gas production as presented in AER ST-98 is provided in these charts as a means of reference and to provide validation for CERI’s estimates 36 Generally, the upgrading process involves removing carbon (via coking) or adding hydrogen (via hydrocracking). The OPTI Orcrude upgrader uses proprietary technology that combines gasification and hydrocracking processes. 37 Syncrude’s upgrading operations include delayed coking (carbon removal) and hydro cracking (hydrogen addition). The proposed Northwest Redwater refinery/upgrader will be a hydro cracking upgrader May 2014

Figures by CERI Given the strong level of activity in the oil sands over the last decade, which has in turn resulted in increasing levels of SCO production and off-gases, there has been an increased availability of SGLs in Western Canada. In 2012, close to 80 percent of the process gas or off-gas available from the upgraders in question was used for upgrading and plant fuel purposes, while less than 20 percent was sent to off-gas SGLs extraction plants. This suggests that a large potential for SGLs extraction from upgraders is currently not being realized. As can be seen in Figure 1.13, CERI estimates SGLs availability has nearly doubled over the past decade from about 57 kb/d in 2002 to over 100 kb/d by 2012. These SGLs present the opportunity for a possible alternative source of petrochemical feedstock but could also be directed to other NGL markets. 38 This timeframe has been chosen given data availability limitations. The OPTI-Nexen project is excluded from this analysis as per comments above. The Lloydminster upgrader is not included as data is not available on the production or use of off-gases. It is assumed that the majority of the process gas in this upgrader is used for upgrading purposes and plant fuel use as it is the case with the upgraders for which data is available 39 Includes the Suncor, Syncrude, CNRL, and Shell upgraders May 2014

Figures by CERI Currently, two projects in AB recover this type of liquid hydrocarbon mix from oil sands upgraders’ off-gases. These are the Williams Fort McMurray extraction plant located in the Athabasca (oil sands) area,41 which started operation in 2002; and the Aux-Sable Heartland off- gas plant located in the Fort Saskatchewan area,42 which started operating in late 2011. Williams also owns and operates a fractionator at Redwater to process olefinic SGLs. On a contractual basis, these plants extract SGLs from the off-gas stream and replace the heating value extracted with the equivalent volume of natural gas, making the economics of such projects very attractive in a low natural gas and high NGLs/olefins price environment.43 Figure 1.14 displays CERI’s estimates for SGLs extraction from these operations over the last decade. To put these figures into context, the estimated 13 kb/d of SGLs extracted in 2012 represented about 13 percent of the estimated 108 kb/d of SGLs in the off-gas stream, but only two percent of the total NGLs produced in Canada in that year. Going forward, the potential for SGLs extraction from these operations will be dictated by the level of SCO production (and thus overall oil sands activity and upgrading operations) as well as by any modifications/expansions or new builds of SGLs extraction plants. 40 See Study No. 130 41 Processes off-gases from Suncor’s Base upgrader 42 Processes off-gases from Shell’s Scotford upgrader 43 Generally reflective of high crude oil to natural price spread May 2014

Natural Gas Liquids (NGLs) in North America: An Update 19 Part I - Upstream United States NGL Production (2002-2012) The shale gas revolution in the United States (US) has driven natural gas production beyond historic levels and has fundamentally shifted the dynamics of other energy markets that compete with or are related to natural gas, such as NGLs. US NGL production has been steadily increasing since 2008 surpassing 3,000 kb/d in 2012. Hydraulic fracking technologies that were first developed in the Barnett Shale in Texas have been transferred to other shale reservoirs, resulting in a significant increase in shale gas drilling. It is the rich NGL compositions in some of these reservoirs that make their development economically viable, even in depressed gas price environments. This trend of increased production of NGLs is likely to continue given the significant size and number of shale basins in the US. Figure 2.1 illustrates some of the major shale basins in the lower 48 states. Figure 2.1: Shale Plays in the Lower 48 States 47 Source: EIA 47 Energy Information Administration, Lower 48 states shale plays, http://www.eia.gov/oil_gas/rpd/shale_gas.pdf May 2014
20 Canadian Energy Research Institute Since NGL prices are typically linked to oil prices, the oil-gas price spread has resulted in exploration and production shifting to liquid-rich plays such as the Permian, Anadarko, Williston, Eagle Ford and Niobrara. Figure 2.2 shows the average gallons of NGLs produced per thousand cubic feet of gas processed (“gallons per mcf” or GPM).48 Figure 2.2: Average GPM of Shale Plays in the Lower 48 States 49 Source: NPC The GPM can vary widely basin to basin. Lean or dry gas typically has a GPM of between 1-2, rich gas between 3-4, and very rich gas greater than 4.50 The National Petroleum Council (NPC) estimates that the average GPM for the US in 2010 was 1.25, however some plays can have GPMs of over 5, for example the Granite Wash play in the Texas panhandle region has the highest average GPM at 5.3, followed by the Eagle Ford in southern Texas at 5.2.51 Of course certain areas within a play will have a higher GPM, for example, some areas of the Marcellus and Utica shales have recorded GPMs of up to 9.52 48 1 GPM = 1 gallon/Mcf x (1,000 mcf/1 MMcf) x (1b/42 gallons) = 1 x 1,000 / 42 = 23 bbl/MMcf 49 National Petroleum Council, Paper #1-13 Natural Gas Liquids (NGLs) Working Document of the NPC North American Resource Development Study, Made Available September 15, 2011 50 In Canada, liquids yields are generally measured in barrels of NGLs per million cubic feet of gas (bbls/MMcf). Lean gas generally has a liquids yield of less than 50 bbls/MMcf, while rich gas is generally up to 100 bbls/MMcf, anything over 100 bbls/MMcf is considered very rich. 51 National Petroleum Council, Paper #1-13 Natural Gas Liquids (NGLs) Working Document of the NPC North American Resource Development Study, Made Available September 15, 2011 52 John C.

Natural Gas Liquids (NGLs) in North America: An Update 21 Part I - Upstream Total NGL production in the US has increased 32 percent since 2005; the majority of this increase can be attributed to NGLs from natural gas processing plants, which increased 39 percent over the same period. Natural gas processing plants produced 79 percent of NGLs in the US with refineries producing only 21 percent.

Figures by CERI In 2012, there were more than 500 natural gas processing plants that in total processed about 48 bcf/d of gas to produce about 2.4 million barrels of NGLs per day. 54 The majority of the gas processing plants are located along the Gulf Coast, in the West Texas/Oklahoma area as well as in the Rockies. The rising supply of NGLs has led to challenges in finding markets and building the infrastructure necessary to move product to markets, both domestic and export. For example, much of the increased ethane supply in the Marcellus region is stranded because of the distance from petrochemical markets in the Gulf Coast area as well as the lack of proper extraction capacity. 53 Energy Information Administration data, http://www.eia.gov/naturalgas/data.cfm#production 54 Energy Information Administration data, http://www.eia.gov/dnav/ng/ng_prod_pp_a_EPL0_ygt_Mbbl_a.htm May 2014
22 Canadian Energy Research Institute Gas Plant NGL Production Ethane makes up the largest proportion of NGLs from natural gas processing plants, accounting for 41 percent in 2012, closely followed by propane at 30 percent. Ethane and propane also account for the majority of growth in NGLs over the decade. Butanes and Pentanes Plus make up smaller contributions, at 17 and 13 percent, respectively, and have also increased, albeit off a smaller base.

Natural Gas Liquids (NGLs) in North America: An Update 23 Part I - Upstream PADDs II and IV have both experienced increases in NGL production, which is consistent with natural gas production increasing in those regions. PADD IV’s (Rockies) share of NGL production has increased from 11 percent in 2002 to 16 percent in 2012. PADD II’s (Midwest) share has increased from 16 percent in 2002 to 18 percent in 2012. Historically, PADD I has produced very few NGLs, but this trend is about to change. Development in the wet (liquids-rich) portion of the Marcellus and Utica shale in Pennsylvania, Ohio, and West Virginia, is drastically increasing the amount of natural gas and NGLs that can be produced in the region. Figure 2.6 shows the increase in natural gas production in the northeast US over the past five years and its effect on inflows from other areas. Figure 2.6: PADD I Production, Demand and Net Inflow from Other Regions 55 Source: EIA Along with this surge in natural gas production, comes an increased volume of NGLs. Companies such as MarkWest are investing in gas plant, pipeline, and fractionator infrastructure in order to produce purity NGL products in the region.56 As investment into NGL infrastructure increases in the region, more and more purity products will be produced and less ethane being produced in the northeastern US will be rejected (not extracted) back into the natural gas stream. Refinery LPG Production In 2012, LPGs produced in refineries accounted for 21 percent of total NGLs produced in the US. Propane and butane together accounted for 17 percent of total refined petroleum products in 2012 from US refineries. Motor gasoline and diesel fuel make up the largest proportion of total output at 63 percent. 55 Energy Information Administration, Today in Energy, Increased Northeast natural gas production reduces net inflow of supply from other areas, http://www.eia.gov/todayinenergy/detail.cfm?id=13851 56 MarkWest Operations website, http://www.markwest.com/operations/utica/ May 2014
