Case Study: Gulf of Thailand Operating Company cuts drilling costs 50% with SLB @balance managed pressure drilling services

Managed Pressure Drilling Service Cuts Drilling Costs 50% in Challenging Ultrahigh-Temperature Wells

SLB helped Gulf of Thailand Operating Company address extreme ultrahigh-temperature offshore drilling challenges in two wells. The operator faced narrow mud-weight windows, formation pressure uncertainty, ballooning, and high nonproductive time while trying to reach total depth.

SLB implemented @balance managed pressure drilling services to maintain bottomhole pressure above pore pressure, define the drilling window, and safely complete the wells. The wells were drilled successfully without wellbore issues, with efficient well control and logging support, saving 20 days of drilling time and cutting well costs by USD 5 million, or 50%.
