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

Published: 08/11/2017

Concrete blue texture
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.

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.
