Through a unique and collaborative approach of competitive service companies, engineering resources were combined and leveraged to identify and mitigate risks of wellbore instability, losses and drilling dysfunctions. Combining service companies’ resources and knowledge allowed to set up a new transversal approach to challenge old paradigms and implement new drilling tools (directional drilling and bits) adapted to this environment.

Rate of Penetration (ROP) improvement roadmap based on data analysis and engineering implemented through the processing of offset wells drilling data, real-time monitoring of Mechanical Specific Energy (MSE) and drilling dysfunctions avoidance. Team spirit-based approach where all actors of the execution embarked on board.

Thanks to this new transversal approach and unique collaboration among all the competitive service companies, an overall reduction of drilling dysfunctions was achieved. Optimization efforts were successfully implemented by following a roadmap which focused on mitigating dysfunctions based on MSE and lithology.
