DRILLING CHOKE AND WELL CONTROL

Choke Control is used when the pressures and fracture pressure gradients are very close with little room for error. With conventional drilling operations the possibility of a kick occurring while not circulating or losing returns while circulating can lead to costly non-productive time resulting in the inability to reach targets. Conventionally these events are addressed by adjusting the hydrostatic pressure through decreasing or increasing the mud weight. This requires both time and expense and the response may not be quick enough to produce the desired results. Choke Control Systems offered by RSSUS are built to provide accurate pressure and well control, especially in the case of a kick through loss of pressure.

Choke Control Panel

· Stainless Steel Skid with lid, lifting eyes & side panels.

· Dual hydraulic shear seal control valves for opening & closing the chokes.

· Air Over Hydraulic pump producing 4.4 l/min at 500 PSI & 1.9 l/min at 3000 PSI

· Emergency Hand pump for low and high pressure producing 0.05 l/min at 10000 PSI

· Bladder type Accumulator once charged to 3000 PSI holds enough volume to fully

open or close both Chokes.

· 5 Gallon reservoir with returns filter, sight glass & drain.

· Rotary valve for adjusting the opening and closing speeds.

· 6” Casing 1 pressure gauge, 0-10,000 PSI

· 6” Casing 2 pressure gauge, 0-10,000 PSI

· 6” Drill pipe pressure gauge, 0-7,500 PSI

· 4” Choke 1 position gauge, open – close

· 4” Choke 2 position gauge, open – close

· 2” Rig air pressure gauge, 0-160 PSI

· 2” Hydraulic Accumulator pressure gauge, 0-4,000 PSI

· Pressure Reducing regulator, 3000 PSI to 300 or 1500 PSI

· Pressure relief valve, set at 3,650 PSI

· Pressure Relief valve, set at either 340 PSI or 1,750 PSI
