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

Pearl Wells Application: Av. 14.9 % Av. 8.9 %
Pearl Wells Application: Av. 59.5 ft/hr Av. 77.2 ft/hr
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
