  2. EPST Electroproject Softtorque Electroproject part of GDF SUEZ organisation Research and Innovation Division (DRI ) CRIGEN Laborelec CIRSEE COFELY • Research subjects • Reduce the costs of the LNG chain • Improve the risk control along the entire LNG chain • Improve operations in LNG terminals • Future - Liquefaction, GTL, NGH, CNG,… Booth 15 www.softtorque.com

  3. The impact of Soft Torque Technology on Drilling Performance Odion Ikhajiagbe Well Engineer Mike Lukyanov Well Engineer

  4. Conclusions: Stick slip is damaging both for equipment and for cores STRS aided Qatar Shell in: Reducing stick slip by 40% Increasing ROP by 30% Reducing bit wear Good quality cores STRS is easy to implement and has shown good results

  9. EPST Electroproject Softtorque Stick Slip Surface torque • Cyclic, heavy torsional vibrations • 3-10 second period • Accelerates up to 5x surface speed in “slip phase” • BHA comes to a complete stop in “stick phase” • BHA accelerates up to 5x surface speed in “slip phase” • Reduced ROP, heavy vibrations down hole motor failures, bit damage • Can occurs 50% of on bottom time (!) Down hole RPM 15 www.softtorque.com

  12. Pearl Wells Application: Av. 14.9 % Av. 8.9 %

  13. Pearl Wells Application: Av. 59.5 ft/hr Av. 77.2 ft/hr

  14. Pearl Wells Application: Improvements in bit performance were observed Less bit wear and more footage drilled per bit IADC bit dull grading was used and same crew applied it Weighted average with respect to footage drilled was taken
