What does remote choke mean?

What does remote choke mean?

Remote Choke: A remote choke is a replica of a hydraulic-actuated choke such as a Cameron or Swaco. This choke can also be used in the well kill. operation. Kill and Choke Lines: Fully operational lines that can be used in circulation or well killing operation.

What is a drilling choke?

An arrangement of piping and special valves, called chokes. In drilling, mud is circulated through a choke manifold when the blowout preventers are closed; a choke manifold is also used to control the pressures encountered during a kick. See Choke, Blowout preventer.

What is choke pressure in drilling?

1. n. [Drilling] A high-pressure pipe leading from an outlet on the BOP stack to the backpressure choke and associated manifold. During well-control operations, the fluid under pressure in the wellbore flows out of the well through the choke line to the choke, reducing the fluid pressure to atmospheric pressure.

What does an automatic choke do?

The automatic choke is the main component that regulates the air/fuel mixture while the engine is being cranked. As the engine warms up, the automatic choke adjusts to the temperature change to regulate the fuel/air mixture to the proper ratio.

Where is the choke manifold located?

rig floor
Weatherford’s choke manifold is typically located on the rig floor and provides flexible and variable flow control and well shut-in capability upstream of the process and measurement equipment during well test operations.

What is choke performance?

Choke Performance Placing a choke at the wellhead means fixing the wellhead pressure and thus the flowing bottom-hole pressure and production rate. For a given wellhead pressure, by calculating pressure loss in the tubing the flowing bottom-hole pressure can be determined.

Can choke kills?

There is no reason for a person to die during the application of a chokehold. When properly applied, the choke hold causes unconsciousness in 10-20 seconds. No fatalities as a result of shime-waza have been reported in the sport of judo since its inception in 1882.

What is the purpose of choke manifold?

In oil and gas production a choke manifold is used to lower the pressure from the well head. It consist of a set of high pressure valves and at least two chokes. These chokes can be fixed or adjustable or a mix of both.

What is the definition of a remote choke panel?

Remote choke panel: A set of controls, usually placed on the rig floor, that is manipulated to control the amount of drilling fluid being circulated through the choke manifold. This procedure is necessary when a kick is being circulated out of a well. See choke manifold.

How is pressure controlled in a drilling choke?

Its function in the system is to ensure pressure control during drilling operations and during a kick (blowout). The pressure is controlled by modifying the relative position of the control elements, gate and seat, by moving the gate. To achieve this, the choke is fitted with a hydraulic actuator with double acting piston.

How many PSI does a superchoke choke handle?

The SUPERCHOKE high-pressure drilling choke control system handles 5,000 to 15,000 psi [345 to 1,034 bar] and is precision engineered for precise well control. Controls can be operated from either remote or onsite consoles.

How does a dual choke control system work?

The dual-choke control console also includes a separate valve that enables regulation of chokes from independent hydraulic systems during special applications. An operator has full command of both chokes without switching controls.
