Horizontal and Complex Trajectory Wells

Torque and Drag Modeling for Horizontal Openhole Completions

With horizontal openhole sections being drilled to lengths that exceed 20,000 ft, placement of the completion string (CS) to planned total depth (TD) may not be possible if the proposed drilling plan is not studied carefully. It is important to model the well before attempting to run the planned completion to determine whether the CS can withstand the strains (tension, compression, and torque) of installation, as well as whether the upper CS has sufficient weight to push the lower CS to TD.
