The Torus insert safety valve enables single-trip, rigless deployment of production-enhancement equipment with an American Petroleum Institute (API) 14A-tested safety valve. The valve—which enables passage of through-tubing coiled tubing, capillary lines, or cables—provides fail-safe protection while allowing faster, more economical operations to extend the productive life of existing wells. Although installing electrical submersible pumps, gas-lift systems, velocity strings, and chemical-injection systems are common approaches to boosting production, maintaining a well barrier during installation and the subsequent production phase is complex and cost-prohibitive. This is because traditional safety valves with flapper-style closure mechanisms require an unobstructed inside diameter for operation. Consequently, a rig has to be mobilized to install these valves deeper in the well below the production enhancement equipment, driving up costs and health, safety, and environmental risks and often delaying operations. By use of a patented sliding-sleeve design to control flow instead of a flapper mechanism, the Torus valve maintains functionality during installation and production while providing a permanent conduit through its center. The valve allows operators to carry out rigless insert string installations in wells that require a qualified safety valve, reducing operational expenses by an average of 50%.
