Background
In a well where temperatures commonly exceeded 280 degF [138 degC], an operator in the Middle East needed to drill a section shoe to shoe in a single run while using an aggressive oil-base mud. In previous runs, motor failures due to the elastomer were common, causing multiple trips and excessive NPT. Schlumberger suggested using the PowerDrive vorteX* powered rotary steerable system with the Powerlast* life-extending motor elastomer from Dyna-Drill.

PowerDrive vorteX RSS and Motor with Powerlast Elastomer Drills to TD in a Single Trip, Increases ROP 20%

Power section showed zero damage after drilling in temperatures greater than 280 degF with aggressive oil-base mud, Middle East

overflow image
The PowerDrive vorteX RSS and the Powerlast elastomer sustained ROP and performance for 186 circulating hours at temperatures greater than 280 degF [138 degC], successfully drilling to TD in a single trip. During drilling, the ROP averaged 26.7 ft/h [8.1 m/h], which is an 20% improvement compared with offset wells. The PowerDrive vorteX RSS with the Powerlast elastomer showed zero damage during the postrun check.
