Blowout Preventer Applications Across the Well Lifecycle

As the ultimate well control safety barrier, API Spec 16A & 16RCD certified Blowout Preventer (BOP) systems are engineered to deliver reliable pressure containment under extreme thermal, high-pressure, and sour service (H2S/CO2) conditions. From deep-well drilling to live-well interventions, our blowout preventer assemblies safeguard personnel, prevent environmental contamination, and minimize non-productive time (NPT) across all operating phases.

BOP Drilling Operations

Drilling Operations

During drilling operations, sudden formation pressure surges or gas kicks demand immediate, high-integrity pressure containment. API 16A certified Ram and Annular BOP stacks rapidly seal the wellbore around drill pipes, collars, or open holes, allowing operators to safely circulate out influxes under full control.

Key Benefits:

  • Continuous pressure control up to 25,000 Psi
  • Rapid dynamic shut-in to prevent catastrophic blowouts
  • Full compatibility with standard drill string sizes and Kellys
  • Minimized NPT during kick tolerance management
BOP Well Completion

Well Completion

Tubing running, packer setting, and wellbore cleanout expose the well to fluctuating formation pressures. Reliable blowout preventers maintain secondary barrier isolation while completion hardware is landed, ensuring seamless and hazard-free transitions to production.

Key Benefits:

  • Safe annulus pressure isolation during tubing installation
  • High-integrity sealing against completion fluids & chemical spacers
  • NACE MR0175 / ISO 15156 compliant for sour completions
  • Reduced operational risk during multi-stage completion
BOP Well Testing & MPD UBD Operations

Well Testing & MPD/UBD Operations

Flowback testing, reservoir evaluation, and Managed Pressure Drilling (MPD / UBD) require continuous surface pressure control. Integrating API 16RCD Rotating Control Devices with standard BOP stacks guarantees dynamic sealing on rotating drill strings and precise return diversion.

Key Benefits:

  • Dynamic sealing up to 17.5 MPa with high-speed rotation (120 r/min)
  • Dependable shut-in performance for high-rate flowback testing
  • Seamless tie-in to choke/kill manifolds and mud-gas separators
  • Reliable surface containment for air, foam, and heavy mud systems
BOP Production & Well Intervention

Production & Well Intervention

Workover, wireline, coiled tubing, and live-well intervention demand constant pressure control without killing the well. Specialized intervention BOPs and stripper systems provide a secure pressure barrier to protect wellsite assets during maintenance and workover routines.

Key Benefits:

  • Secure barrier control during live-well coiled tubing/wireline operations
  • Continuous containment during workover and tubing replacement
  • Corrosion-resistant alloy (CRA) clad options for high-H2S/CO2 wells
  • Enhanced field reliability with PR2 performance verification

FAQs about Blowout Preventer

A Blowout Preventer (BOP) is a specialized high-pressure valve system installed at the wellhead to prevent uncontrolled kick fluids (crude oil, natural gas, or drilling mud) from escaping during drilling, completion, or workover operations. It operates by rapidly sealing the annular space around the drill pipe, shearing the drill string, or completely closing off an open wellbore under emergency conditions.

Our API Spec 16A & 16RCD compliant BOP systems support standard working pressure ratings of:2,000 Psi / 3,000 Psi / 5,000 Psi (Low to Intermediate Pressure)10,000 Psi / 15,000 Psi / 20,000 Psi / 25,000 Psi (High Pressure & HPHT)Main bore sizes range from 7-1/16” to 21-1/4”, accommodating diverse well control stacks and casing programs. Custom pressure configurations are available upon request.

Yes. Our BOP bodies, rams, and internal components can be manufactured in compliance with NACE MR0175 / ISO 15156 standards (Material Class DD, EE, FF, HH). We also offer internal Corrosion Resistant Alloy (CRA) clad inlaying (such as Inconel 625) for extreme H2S and CO2 sour environments.

Every BOP stack undergoes 100% rigorous factory acceptance testing (FAT), including:

  • Ultrasonic & Magnetic Particle Non-Destructive Testing (NDT)
  • Full-body Hydrostatic Shell Test & High/Low Pressure Seat Test (up to 25,000 Psi)
  • Hydraulic Locking & Operating Function Verification
  • PR2 Performance Level Verification & Certified Mill Test Reports (MTRs) to EN 10204 3.1/3.2.

Absolutely. Our BOPs, drilling spools, and rotating control devices (RCDs) are built to standardized API flange, stud, or clamp-type end connections. They seamlessly integrate with standard API 6A casing heads, choke & kill manifolds, and third-party BOP control units (accumulator skids).
