Introduction to Subsurface Safety Valves
Schlumberger, with its Petrel line of subsea safety valves, has been at the forefront of innovation in the oil and gas industry since the late 1950s. These safety valves play a critical role in preventing uncontrolled flow in wells in case of catastrophic damage to wellhead equipment. The fail-safe closure of these valves ensures the security of the well while maintaining the ability to produce from it. Petrel's SSVs surpass industry standards, exceeding requirements for pressure integrity, leakage acceptance criteria, and slam closure outlined in ISO 10432 and API Spec 14A.
Advanced Technologies in Safety Valve Design
The Petrel safety valves feature advanced technologies like GeoGuard™ DW for deepwater applications, SlimTech™ for gas environments, Integrity™ for high-pressure/high-temperature settings, and Recovery™ for wireline retrievability. These valves are equipped with multizone seal technology that enhances reliability and performance, ensuring robust operation even in demanding conditions.
Setting-depth Flexibility and Actuation Options
Petrel offers a diverse portfolio of API Spec 14A–certified SSVs with operational flexibility to meet various challenges in the industry. With multiple actuation options available for different setting depths, Petrel valves ensure safe and reliable operation across a wide range of applications. Whether for shallow-set, deepset, or ultradeepset scenarios, Petrel's SSVs provide the necessary actuation mechanisms for optimal performance.
Proven Performance and Validation
Petrel's multizone seal technology has undergone extensive validation to ensure reliability, longevity, and performance. Using a transparent piston bore, the design team can monitor the seal's dynamic and static performance in real-time, simulating downhole pressure and temperature conditions. The GeoGuard and Integrity SSVs, incorporating this technology, are validated to API Spec 14A V1-R and V1-HR, providing a seal of quality and performance.
Enhancing Completion Efficiency with Petrel Safety Valves
In conclusion, Petrel's innovative subsurface safety valves are pivotal in ensuring the security and efficiency of well completions in the oil and gas industry. With a focus on technological advancement, reliability, and industry-leading performance, Petrel continues to set the standard for safety valve solutions that safeguard people, the environment, and valuable assets in the oil and gas sector.
