Leishen Energy Group is a small China-based oil and gas equipment and services company focused on the upstream sector. Leishen's two core products are reciprocating compressors — used to boost pressure in gas wells, inject gas into oil reservoirs, and move gas through pipelines — and wellhead safety control systems, which automatically shut wellhead valves in hazardous conditions. Leishen claims to be the only Chinese manufacturer of ultra-high pressure reciprocating compressors (up to 52MPa), and its wellhead safety systems carry UK Bureau Veritas certification. Other products include flexible composite pipes, heating systems, gas sampling systems, and skid-mounted pressure control equipment. Leishen sells primarily to large state-owned Chinese oil companies, particularly PetroChina's Northwest Oilfield operations. Beyond equipment sales, Leishen leases compressors to oilfield operators and provides ongoing maintenance, spare parts, and technical personnel support — the company claims to be the largest natural gas compressor rental provider in Southwest China. Leishen also operates an LNG liquefaction plant and a CNG refueling station in Chengdu, selling gas to industrial customers and trading natural gas to fill production gaps. A fourth segment provides digitalization and IT integration services for oilfield management. Leishen's operations are concentrated in Sichuan Province, with customers in Northwest and Southwest China, and the company has begun exporting to Pakistan and Indonesia, with stated ambitions to expand into the Middle East.
