3 Odion Ikhajiagbe Well Engineer The impact of Soft Torque Technology on Drilling Performance 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 4

9 9 Stick Slip 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 (!) Surface torque Down hole RPM EPST Electroproject Softtorque

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 14 feet/bit Bit Wear Inner TeethOuter Teeth With-Out STRS With STRS % Improvement
