first break volume 29, April 2011 news feature Can the Dutch Gas Bubble defy King Hubbert’s Peak? The Peak Oil theory may be on its way to being confirmed by the depletion of Europe’s largest natural gas field, which can only be rescued by a new era of gas exploration. This would also delay Europe’s growing dependency on foreign gas imports. Ruud Weijermars1* and Elaine Madsen2 examine whether past success can be equaled by future exploration initiatives.

With so much gas in the ground proven by geological research, the remaining problem could be solved: gas could be produced and sold at a profit if a market was physically tied to the wellhead by a pipeline distribution system.
