oa Drilling and Completion Fluids Design for Horizontal Well Drilling – Case History from Raudhatein Field

This paper describes the performance of customized drilling fluids in a horizontal well as compared to standard drilling fluids used in offset wells. A comprehensive engineered approach to the challenges of drilling horizontal wells using a novel bridging technology to deliver improved wellbore stability and reduced non-productive time (NPT) related to losses, stuck pipe, etc. This paper also describes how the completions fluids minimized reservoir damage and utilized Mesophase technology to remediate near-wellbore damage and improve reservoir producibility. The lessons learned on well RA-492 were incorporated in drilling future wells.
