Walking the Line Through
Narrow Operating Windows

Apply Constant Bottom Hole Pressure (CBHP) and Adapt to Pressure Changes–In Real Time

Traditional drilling methods struggle with narrow windows. The margin for error is small — and so is the tolerance for risk. Enhanced Drilling's EC-Drill® system offers a smarter, safer way forward with the ability to hold a CBHP and adjust real-time according to actual well conditions.

It enables consistent and safe drilling — even when the operating window leaves no room for error.

Constant Bottom Hole Pressure (CBHP)

The classic MPD approach. Maintain a near CBHP for all operations to steer through the narrow windows without inducing losses or causing influxes. By adjusting the fluid level in the Riser, the pressure in the well is kept near constant for static and dynamic conditions.

Smart Pressure Control

To safely and efficiently navigate Narrow Operating Windows, you need technologies offering more than just control — you need a tool with adaptability and the ability to perform continuously for all operational phases. Our solution is purpose-built to help you maintain pressure stability, reduce risk, and stay on schedule — even in the most demanding wells while drilling, tripping and cementing. Receive instant feedback on gains or losses and adjust your setpoint value according to actual well conditions.
