Novel Case History: Managed Pressure Cementing Record Under HT-HP Conditions

Abstract

The managed pressure cementing technique is new in relative terms to the past 100 years of industry cementing experience (e.g., circa 2008 with first publication). The technique is becoming more prevalent to overcome challenging well integrity requirements which should help the industry achieve zonal isolation for applications previously deemed too difficult to isolate with cement. A literature review of managed pressure cementing (e.g., MPC) success documented in the public domain shows, at the time of the manuscript preparation, the subject case history is the deepest, hottest, and heaviest application. The same literature review identifies several case histories deeper, not hotter or heavier as well as heavier not deeper or hotter. The manuscript shares the challenges faced and success factors to overcome the deployment risks helping to isolate a challenging openhole section using managed pressure cementing.
