Traditional Softtorque (STRS) Technology Resume: Traditional Softtorque (STRS) technology. • Suitable for vertical well operations. • Drill pipe size from 5” up. • Drill depth up to around 5000 m. • Standard STRS technology needs continues tuning while drilling. • Electroproject EPST system can be upgraded with Autotune module • Suitable for DC TD’s. 25 juni 2021 26 www.softtorque.com

Electroproject Advanced Softtorque
AST
25 juni 2021 27 www.softtorque.comTechnical Presentation softtorque
AST technology minimize drill bit speed variations caused
by bit torque disturbance, delivering :
• a “wider” working envelop for stick-slip mitigation
allowing for larger WOB
• Better performance when drilling with “thin” pipe
• Better performance a greater depth.
• Better performance in horizontal wells and lighter BHA.

TTA5 – 12 ¼” hole – 13kft MD / Top drive inertia = 1750 [kgm^2]
New technology: Advance Softtorque
AST properties:
• Shape of reflectivity curve is adaptable on operation.
• Stability algorithms take the drill string property's into account.
• Higher modi damping up to 3 Hz.
• Low TD excitation with minimum drill bit speed disturbance.
25 juni 2021 31 www.softtorque.comTechnical Presentation AST
What brings makes AST unique:
• Proved and recognized SoftTorque system.
• Designed to be embedded in all electrical TD’s (AC and DC)
(DC systems to be executed with encoder feedback).
• Widest control spectrum. Stick slip mitigation for higher modi.
• Low speed incursions while controlling. Not violent reacting TD.
• Highest crossover frequency. Immune for higher modi oscillations.
• Capability to investigate performance using expert tools to advice
improvements.

Electroproject Ztorque
25 juni 2021 33 www.softtorque.comTechnical Presentation softtorque
Ztorque (Zt) is designed as a wide band impedance (Z)
matching concept. The technology is based on transmission
line theory with underlying ambition to absorb all torque
waves arriving at the TD, delivering :
• a “wider” working envelop for stick-slip mitigation
allowing for larger WOB
• Better performance when drilling with “thin” pipe
• Better performance a greater depth.
• Better performance in horizontal wells and lighter BHA.

Angel
I can confirm that two advanced soft-torque systems were installed on KDC-57 and 42.
For the installation on KDC-57, a success flyer was made. Comments made by the Senior Well Engineer
“Advanced soft torque was installed in KDC-57, the stick slip was dramatically reduced and the ROP was improved especially in the 6 1/8”
section.”
