Introduction to Well Remediation
In the oil and gas industry, maintaining and restoring well integrity is crucial for sustaining production levels. When safety valves fail in wells, operations can be severely impacted, leading to production losses and potential safety risks. Schlumberger's GEM-Valve retrievable wireless subsurface safety valve system offers an innovative solution to address these challenges.
Restoration of Wells
The GEM-Valve system is designed to restore both operating and shut-in wells that have encountered safety valve issues. By enabling operators to fix downhole safety valve problems, this system helps in regaining control over production and optimizing well performance. This intervention not only brings financial benefits to operators but also helps in maintaining hydrocarbon production levels.
Key Features of GEM-Valve System
One of the key features of the GEM-Valve system is its wireless operation, which allows for surface control of the safety valve without the need for hydraulic control lines. This feature offers flexibility and reliability in managing subsurface safety shut-in equipment, ensuring regulatory compliance and efficient production of oil and gas wells. Moreover, the fail-safe normally closed system ensures the safety and integrity of the well at all times.
Operational Advantages
Operators can benefit from the GEM-Valve system in various ways. By installing this system as a temporary safety valve solution, production deferral can be eliminated while planning for workover interventions. In cases where a permanent solution is required, the GEM-Valve system helps in avoiding significant workover repair costs, especially for old producing wells in mature fields. This cost-effective approach makes it a compelling choice for operators looking to maximize production efficiency.
Industry Compliance and Certifications
The GEM-Valve system is API certified and monogrammed, ensuring that it meets industry standards for safety valves. Its ability to control multiple valves from a single surface panel adds to its operational efficiency and ease of use. Additionally, the system's tolerance to downhole flow and pressure variations makes it a reliable solution for preventing undesired valve closures, a common issue with traditional remediation methods.
