Automatic and precise high-pressure control at 3,000 psi, 10,000 psi, and 15,000 psi

The AUTOCHOKE choke is ideally suited for pressure-intensive underbalanced drilling (UBD) and managed pressure drilling (MPD) applications. It automatically regulates casing pressure under all conditions, including during mud pump startup or shutdown and when making and breaking drillpipe connections.

LOW-PRESSURE AUTOCHOKE precision drilling choke console

The LOW-PRESSURE AUTOCHOKE console is engineered for low-surface-pressure MPD and UBD up to 1,500 psi. The console provides accurate control of the AUTOCHOKE pressure-balanced drilling choke within a range of ±50 psi. The console enables operators to seamlessly transition between multiple AUTOCHOKE chokes while simultaneously controlling two units. Under normal operation and once the backup devices are charged, both chokes maintain pressure for more than 2 h after loss of rig air and up to 1 h after loss of rig power.
