Managed Pressure Drilling, Underbalanced and Overbalanced Drilling & Pressure Control

Overview Library

Pressure control technologies and engineering expertise

M-I SWACO provides the most advanced technologies and engineering expertise to help operators ensure wellbore stability and pressure control in overbalanced and underbalanced drilling applications in challenging downhole environments. Our managed pressure drilling approach includes innovative products to meet challenging controlled pressure drilling needs. Our services and field-tested engineering know-how help ensure proper dynamic annular pressure control that allows operators to reduce non-productive time, promote safety and cut costs.

Advanced pressure control solutions

Controlling pressure while drilling is crucial for operators facing narrow pressure margins, unstable boreholes and uncertain pressures that can raise safety risks and increase non-productive time and costs. M-I SWACO utilizes an engineering approach called @balance services to assess anticipated drilling conditions and identify solutions as part of our advanced pressure control services.

Innovative products and services

Our @balance services help prevent, detect and mitigate potential well control events and optimize wellbore stability through innovative engineering and services for drilling pressure control, kick detection, fluid separation, and nitrogen gas applications. Technologies include state-of-the art drilling chokes, choke manifolds, gas flow measurement systems, separators, and pressure and fluid management systems.
