Description
ABSTRACT
The presentation will introduce the new EC-Drill Managed Pressure Drilling system, and the history of its development. The principals of operation are explained and major components along with their functions shown. Also covered in the presentation is a brief examination of integrating the system into a floating drilling rig along with the process to accomplish the integration in a safe and expedient manner.
A new Managed Pressure Drilling (MPD) system for floating drilling rigs has drilled four wells as of November 2014, with two more wells in progress. Two of the wells were multi-lateral wells with three legs each. This new MPD system uses pumped riser technology to control bottom-hole pressure, optimizing well bore pressure profiles. The system also compensates for Equivalent Circulating Density (ECD). The benefits of the system are numerous, but include improved safety, and early influx/loss detection. Active management of well bore pressures allows drilling through narrow pore/fracture pressure margins, extending the length of horizontal laterals, reducing mud losses and drilling through depleted or other difficult formations.
Case histories of the most recent operations will also be shown, including operations on the Norwegian continental shelf and in the Gulf of Mexico. The case histories will cover the reason EC-Drill was selected for the particular environment, benefits obtained, and use of the system in post kick operations.
