Equalizing assemblies can be used in conjunction with lock mandrels to assure optimal subsurface flow and pressure control down the wellbore on wireline worksites. Pressure control is one of the most important factors of maintaining a productive and safe wireline site. Western Pressure Controls understands the needs of oil and gas workers, and those looking to ensure the long-term safety of the industry. That is why we offer a variety of equalizing assemblies, in two styles, to suit the specifics of any wireline site.

Our equalizing assemblies come in two styles: Baker and Otis.

Baker-style Equalizing Assemblies

B-choke assemblies
B-choke assemblies are used to provide restriction of flow in gas wells, and to control and eliminate hydrates or sand bridges from far along up the well. Our b-choke assemblies are available with choke beans. You can also choose back-up rings instead of the standard o-rings. As is required, they are available in different no-go sizes.

G-equalizing assemblies
When required to hold pressure from both above and below, this blanking tool could be the right choice, when assembled with the S, W, or Z lock (depending on what type of landing profile the plug is to be set into). This tool comes with two types of fishneck prongs: one suitable for W and Z locks, the other for S locks. The standard packing is nitrile Kevlar, but other types are available upon request.

Otis-style Equalizing Assemblies

A-choke assembly
When used in conjunction with the x/xn locks, this assembly allows for limiting flow to a predetermined quantity, while maintaining the option for pumping down the tubing, if required. The choke bores on this assembly are drilled to your specifications.

X-equalizing assembly
Attached to an X or XN locking mandrel, the px-equalizing assembly allows for pressure differentials to be held above or above. This assembles with the corresponding size of lock needed; parts 1 and 2 are interchangeable.

T-choke assembly
This assembly allows for continuous flow upwards at a controlled rate. With the t-choke assembly, you retain the ability to pump down the wellbore. Additionally, kobes plugs are available with this assembly in the case of a restricted orifice.
