Detect and control influx events earlier through advanced pressure control options.
Superior Pressure Control for the Most Challenging Wells
EC-Drill® Dual MPD combines Controlled Mud Level (CML) and Surface Back Pressure (SBP) to deliver next-generation pressure control for offshore drilling.
What is EC-Drill® Dual MPD?
EC-Drill® Dual MPD is a managed pressure drilling system that combines two complementary pressure control methods:
-
Controlled Mud Level (CML): Adjusts the fluid level inside the riser to create a dual gradient effect and control bottom hole pressure.
-
Surface Back Pressure (SBP): Applies controlled pressure at surface to manage annular pressure and stabilize the well.
Operators can switch seamlessly between CML and SBP modes, allowing continuous drilling even when well conditions change rapidly.
This flexibility makes EC-Drill® Dual MPD particularly valuable in deepwater wells, depleted formations, and operations with narrow drilling margins.
Why Operators Choose EC-Drill® Dual MPD
Offshore wells are becoming increasingly complex. Narrow pressure windows, depleted formations and high influx risk make conventional drilling approaches less effective. EC-Drill® Dual MPD helps operators maintain control and efficiency throughout the well.
Engineered to meet the toughest offshore challenges, EC-Drill® Dual MPD improves safety, reduces rig time, and enhances drilling.
Here’s what sets it apart:
Switch between CML and SBP modes without interrupting operations.
Maintain stable bottom hole pressure and avoid unnecessary well control events.
Maintain a controlled pressure profile even in challenging well conditions.
