15,000-psi choke for kick control, well testing
The M-I SWACO 15K CHOKE is among the most widely used and respected well killing and high pressure control drilling chokes in the industry. The 15,000-psi choke has been used effectively top control kicks, well testing and well clean-up operations. It is designed and manufactured for hydrogen sulfide service and abrasive fluid applications.
Three methods of operation:
-
Normal operations – activation is rig air operated.
-
If rig air is lost – activation is manual with hydraulic pump located on remote control skid.
-
If hydraulic lines are severed – activation is manual with bar provided on indicator head.
Features and Benefits:
-
Built To Handle the Pressure – The 15K CHOKE is precision- engineered for precise well control under harsh and demanding conditions.
-
Unique Choke Plate Design – Heavy duty diamond lapped tungsten carbide plates are honed to a flatness measured by light bands and feature unique half-moon shaped orifices. Rotation of the actuator fork allows finite regulation of the size of the opening from full open to full close.
-
Positive Closure – A 17°-dead band overlap beyond the full close position is designed to ensure closure even if the plates become worn following extended exposure to abrasive laden fluid flow. Pressure drops or surges will not affect the quality of the seal in the plate-to-plate design. In fact, the seal improves under pressure.
-
Tungsten Carbide Wear Sleeves – Tungsten carbide wear sleeves increase in-service life. Extended wear sleeves are available to absorb effects of abrasive downstream turbulence especially during underbalanced drilling operations.
-
Versatile – Ideal for onshore and offshore applications. Controls can be from either remote or on-site consoles.
