Title: Application of Hydraulic Port Collars in Two Stage Cementing Operations Reduces Rig Time and Drilling Cost in the Permian Basin

Abstract
Operators in the Permian Basin have been performing two stage cementing operations on their casing strings for decades utilizing conventional diverter tool technology, often in combination with casing annulus packers.

Over time, issues with legacy diverter tools (DV) have been identified and solutions sought. These issues range from longer than desired time to drill-out the DV tool, reluctance to drill-out a DV tool with a directional assembly due to drill bit dulling and premature drilling motor/MWD failures, damage to the DV tool while drilling causing leaks and remediation and an inability to pressure test the whole casing string after cementing. A development effort was made to eliminate these issues. The Hydraulic Port Collar (HPC) was designed and extensive qualification/testing of the HPC design was performed prior to field deployment. Running procedures were written and revised in consultation with a variety of operators. Several wells were identified for field trials. The wells were selected based on the operator’s desire to eliminate a DV tool drill-out. The wells had complex directional plans that required high bend drilling motors resulting in the operator’s reluctance to drill-out conventional DV tools with the curve BHA’s.

This presentation will review the results of the field trials and document efficiency gains up to 40% when compared to previous operations where legacy DV tools had been deployed.
