Choke valves are used to control flow rate and reduce pressure for processing of produced fluids farther downstream. Effective chokes reduce the likelihood of damage to downstream equipment, support longer lasting production timespans, and alleviate stress from field operators by keeping them away from the wellhead.
Our chokes are also economical and provide the lowest total cost of ownership in the industry. As a global manufacturer and supplier of chokes for the oil and gas production market, we can provide a fit-for-purpose solution for any application.
Selecting the proper trim for your application and environment is crucial and can help avoid expensive damage such as erosion and corrosion. We offer the following geometries:
Our external sleeve trim enables an effective impingement process that efficiently dissipates energy and reduces velocity using the latest in fluid-management dynamics.
The use of micron-grade carbide and proven binding agents provides durability, controllability, and repeatability to best support your well management program even when faced with “sand producers.”
Our plug and cage trim is frequently used when high flow and controllability are needed for injection or conventional oil and gas production. Features include submicron grade carbide, metal bonnet seal, threadless body, fully guided cage trim, and high Cv capacity.
Our stacked disc is designed with a semi-circular porting pattern that offers longer wear life. These chokes are primarily used for two types of service:
Intermitter trim synchronizes with artificial lift which gives operators the ability to use choke body in service and convert it to handle gas lift applications without in-line removal of choke body or replacing with another value type.
Our dual stage low flow trim is used with methanol and ethylene glycol (MEG) injection or service applications. This trim functions well in specialized service with very high temperatures.
Our needle and seat trim provides a robust solution for severe conditions during drill outs, flowback, sand dumping, and early production where plug parts and debris may be present. With the use of NOV's micron-grade carbide and proven binding agents this trim provides durability, controllability, and repeatability to best support your well management program even when faced with the most challenging applications.
Our most economical offering for only positive style chokes, bean and caged bean trim is used for static pressure control with the bean often used to create back pressure and the caged bean performing well during high pressure drops.
With high quality products and considerate service, we will work together with you to enhance your business and improve the efficiency. Please don't hesitate to contact us to get more details of choke manifold.
