China Vigor Energy Technology Co., Ltd.

China Vigor Energy Technology Co., Ltd. is a Chinese manufacturer of downhole completion tools and oilfield tubular products, holding API Monogram certifications under API Spec 11D1 (Packers and Bridge Plugs, license 11D1-0245), API Spec 5B (Threading, Gauging, and Thread Inspection, license 5B-0369), and API Spec Q1 (Quality Management System, registration Q1-5390). The company specializes in the design, manufacture, and quality-controlled threading and inspection of downhole isolation tools and oil country tubular goods (OCTG) for the petroleum and natural gas industry. Core product lines include mechanically set and hydraulic set packers, bridge plugs, cement retainers, and API-threaded casing and tubing products. The API 5B certification covers casing and tubing thread machining, gauging, and thread inspection in compliance with API Spec 5B, which governs dimensions, tolerances, and marking requirements for API threads used in oilfield casing and tubing connections. The API 11D1 certification authorizes the company to stamp the API Monogram on packers and bridge plugs meeting the performance, material, and testing requirements of that specification, covering permanent, retrievable, and inflatable packer types. The API Q1 registration confirms that the company operates a certified quality management system meeting the petroleum industry's stringent requirements for manufacturing organizations. China Vigor Energy Technology is positioned as a lower-cost supplier of API-certified completion tools and tubular threading services, primarily targeting operators and service companies active in China's onshore oil and gas basins as well as export markets in the Middle East, Southeast Asia, and other regions where Chinese-made API-stamped downhole tools are commonly procured.
