168952 – Case studies and best practices for installation of open hole multistage completions systems in wells drilled underbalanced

Summary

Underbalanced drilling has been proven to mitigate formation damage, increase rate of penetration (ROP), and reduce differential sticking of the drill string. This paper describes the benefits of using open hole multistage (OHMS) completion systems in unconventional wells that have been drilled underbalanced. While underbalanced drilling and completion is not the standard, it is being utilized significantly in the United States due to reservoir characteristics.
