A critical safety device installed on oil and gas wells to prevent uncontrolled release of formation fluids during drilling operations.
Technical details and manufacturing context for Blowout Preventer (BOP)
| Parameter | Typical range | Notes & selection driver |
|---|---|---|
| Rated Working Pressure | 14–140 MPa | Higher pressure ratings require heavier construction.API 16A |
| Nominal Bore Size | 179–540 mm | Must match wellhead and casing size.API 16A |
| Temperature Rating | -29–121 °C | Outside range elastomers may fail.API 16A |
| Sealing Element Life | 50–200 cycles | Depends on mud type and pressure. |
| Closing Time | 5–30 s | Faster closure reduces kick volume.API 16A |

The primary function is to seal, control, and monitor the wellbore to prevent uncontrolled release of formation fluids, thereby preventing blowouts during drilling, completion, and intervention operations.
Rated working pressure typically ranges from 14 to 140 MPa, and temperature rating from -29 to 121 °C, per API 16A. These values must be verified for the specific model and application.
The BOP is controlled remotely from a control panel (accumulator unit) on the rig floor, using hydraulic or mechanical force to actuate the sealing elements.
Relevant standards include API 16A for pressure ratings, bore size, temperature, closing time, and hydraulic operating pressure, and API 16D for control system pressure. Always verify compliance with the manufacturer.
