Optimization With Real-Time Monitoring Results in Enhanced Drilling Performance

This paper describes how severe rig limitations were overcome through an optimization plan in which an optimal bottomhole assembly was designed and drilling practices were customized.

This project drilled horizontal wells with bottomhole assemblies (BHAs) with a topdrive as the primary drive mechanism. The rig in question was struggling to provide not only the required rotational speed but also to deliver consistent necessary torque. The complete paper analyzes how severe rig limitations were overcome through an optimization plan in which the optimal BHA was designed, and drilling practices were customized, for safe and successful execution of wells.

Challenge

The project involved drilling multiple re-entry wells for oil and gas production. A typical well design in this operation featured a whipstock set in a 9⅝-in.
