Pressure-balanced drilling choke
Achieve easier, more precise well pressure control.
Engineered for low-surface-pressure MPD and underbalanced drilling up to 1,500 psi, the LOW-PRESSURE AUTOCHOKE 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 drilling 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.
