Managed Pressure Drilling (MPD)
Precise wellbore pressure control to drill narrow margins safely and efficiently.
Overview
Managed pressure drilling (MPD) precisely controls the annular pressure profile so you can drill safely through narrow pore-pressure / fracture-gradient windows. Returns are taken through a rotating control device (RCD) and routed to our four-phase separator and 5,000-psi automated choke manifold, where real-time data lets us hold a constant bottom-hole pressure, detect influxes early and react within seconds.
Key benefits
- Drill previously undrillable narrow-margin wells
- Early kick detection and dynamic well control
- Reduced non-productive time and casing strings
- Mitigation of lost circulation and ballooning
Typical applications
- Narrow pore-pressure / fracture-gradient windows
- Depleted reservoirs and HPHT wells
- Fractured carbonate formations
Equipment we run for this service
A self-sustaining, field-proven spread — owned, maintained and operated by our own crews.
Rotating Control Device (RCD)
Seals the annulus while the drill string rotates and safely diverts returns to the separator — the heart of every underbalanced and managed-pressure operation.
Choke Manifold
A 4", 5,000-psi double-gut manifold with a PLC-controlled automated choke and remote-operated valves that sets and holds the precise backpressure used to control the well.
Four-Phase Separator
Closed-loop surface vessel that cleanly separates gas, oil, water and solids from the returns, handling up to 30,000 bbl/day of fluid and 40 MMscf/day of gas. Built to ASME VIII and ABSA standards.
Flare Stack
A 45 ft hydraulically raised flare stack with electronic igniter and propane pilot that safely burns off produced gas during underbalanced and managed-pressure operations.
Data Monitoring System
Continuous real-time monitoring of injection and choke pressures, gas and fluid flow rates, choke position and fluid gain/loss — giving the crew full visibility and early kick detection.
Accumulator Unit
A 42-gallon, nitrogen-backed hydraulic accumulator (0–1,500 psi) that powers well-control functions and the RCD, providing fast, reliable actuation when it matters most.
Air Compressors
The primary high-volume air supply that powers the whole system, delivering the volume needed to lift cuttings and drive the hammer. A fleet of Atlas Copco and Sullair units.
