Description:

The annular blowout preventer is responsible for sealing the space around the drill pipe (annular space). It achieves that by regulating the airflow to prevent mud, ensuring that the system operates efficiently. The annular BOP is usually placed on top of the BOP stack for efficient airflow control in the system.

An annular blowout preventer is a large valve designed to seal, control, and monitor oil and gas wells. These BOPs have elastomeric sealing, a valve resembling a large rubber donut, which mechanically squeezes inward to seal the drill string, casing, open hole, or pipe. The valve rotates during drilling to maintain a seal around drill pipes.

The annular blowout preventer performs several functions in drilling operations. It seals the annular space between the tubing, casing, and drill pipes. It also helps maintain the seal when the casing, tubing, or drill pipes are out of the drill hole. Unlike the RAM blowout preventers, the annular BOPs can seal various pipes of different sizes.

When working with moving parts in drilling operations, you need dependable equipment you can trust. Our annular blowout preventers’ spherical design allows proper sealing of open holes on various pipe sizes. Annular blowout preventers (BOPs) also provide reliability in high-pressure situations.

Use our annular BOPs at the top of BOP stacks for improved well pressure control during drilling and workover operations. Ideal where space is a priority, the straightforward design and operating system have been proven and accepted for safe operation in all oil and gas areas in the world. Its five main components (lower housing, upper housing, piston, adapter ring, and packing element) allow for easy maintenance and reliability. Stripping of drill pipes, tubing, and wireline through the packing element can also be accomplished at lower pressures.

Features & Benefits of Annular BOPs

Steel inserts prevent extrusions of the rubber and feed inward to close on any pipe or tubular in the wellbore.

Replaceable bearings are used in the operating system to prevent metal contact of moving parts.

Adapter ring located below the upper housing prevents contamination of the operating system during packing element replacement.

Wedged cover upper bearing is also available.

Available in all standard bore pressure ratings

Special rubber materials available for non-standard environments.

Applications:

Annular Blowout Preventers (BOPs) are critical components in well control systems, designed to prevent the uncontrolled release of hydrocarbons during drilling and completion operations. Here are some key applications of annular BOPs:

1. **Well Shut-In During Drilling Operations:** Annular BOPs are used to seal the annular space between the drill string and the wellbore during drilling. This allows for well shut-in to control pressure and prevent the uncontrolled release of fluids or gas.

2. **Kick Control:** In the event of a kick (the influx of formation fluids into the wellbore), annular BOPs are activated to close the wellbore annulus, isolating the well from the formation fluids and enabling the drilling crew to regain control.

3. **Secondary Well Control:** Annular BOPs provide a secondary means of well control in conjunction with other blowout preventers such as ram BOPs. They serve as a backup system to prevent blowouts in case primary control methods fail.

4. **Pressure Testing:** Annular BOPs are used to perform pressure tests on the wellbore and casing to ensure the integrity of the well's barriers and the equipment downhole.

5. **Casing and Tubing Operations:** During casing and tubing operations, annular BOPs are employed to secure the wellbore annulus, allowing for the installation or removal of casing, tubing, or other downhole equipment.

6. **Wellhead Maintenance:** Annular BOPs are utilized during wellhead maintenance operations, providing a means to isolate the wellbore and control pressure while performing maintenance tasks.

7. **Surface Testing:** Annular BOPs are involved in surface testing procedures to evaluate the integrity of the wellbore and downhole equipment, ensuring compliance with safety and regulatory standards.

8. **Well Abandonment:** When permanently abandoning a well, annular BOPs play a role in maintaining well control during the plugging and abandonment operations.

9. **Drilling Through Depleted Zones:** Annular BOPs are used when drilling through zones with lower pressure, helping to control the wellbore and prevent influxes.

10. **Subsea Operations:** In subsea drilling and completion activities, subsea annular BOPs are employed to perform the same functions as their surface counterparts, ensuring control over the well in underwater environments.

Annular BOPs are versatile and crucial components in well control systems, providing a flexible means of sealing the wellbore annulus under various operational conditions and contingencies.
