Accurate, Precise Control for MPD & UBD Applications
Proactive and reactive pressure control services for managed pressure drilling and underbalanced operations include a wide selection of chokes, stand-alone manual control or automated dynamic control systems, and engineered plans and procedures. Control solutions are tailored for each application based on the degree of control required.
Reactive and proactive pressure control
For purely reactive control over a wide pressure margin, manual and digital consoles are available that control one or more stand-alone chokes. Dynamic systems are available for applications requiring proactive pressure control over a narrow margin. Proactive control services include an integrated system of chokes, valves, pumps, and alarms to manage the annulus pressure within a given set of narrow limits during every phase of drilling.
Pressure control solutions can be further tailored with a selection of chokes, including automated gear and piston chokes, M-I SWACO e-chokes and high-pressure autochokes, and small-footprint manifolds rated for high-pressure, high-flow, and severe H2S conditions.
Pressure control in multiple environments
Drilling pressure control service performance has been proven in severely depleted onshore and deepwater reservoirs; high-angle multiphase MPD and UBD wells; horizontal shale gas wells, HPHT and geothermal reservoirs; and drilling with casing, cementing, and closed-loop pressure control with wired drillpipe.
The dynamic annular pressure control system is a benchmark automated MPD system. It is the first to incorporate a real-time hydraulics model capable of simultaneously controlling multiple chokes and a backpressure pump to provide a singular level of field-proven performance, accuracy, and response.
The low-pressure autochoke console (LPAC) is a unique, easy-to-use, and simple-to-install digital control console that includes a touchscreen human machine interface that provides precise pressure control in MPD and UBD operations.
Drilling and well control chokes include industry leading high pressure M-I SWACO chokes for well control, and managed pressure, underbalanced, and coiled tubing drilling. These include the AUTOCHOKE, 10K SUPER CHOKE, and eCHOKE, all known for their robust, fast-acting performance and their precise ability to control fluid flow at pressures up to 20,000 psi.
Easy to operate single or dual autochoke control units come with a choice of either standard pressure gauges or state-of-the-art digital gauges for low and high pressure applications.
