What Shengji Group does

Shengji Group (also operating as Shengji Petro) is a privately-held Chinese oil and gas equipment manufacturer founded in 1964 in Dongying, Shandong Province, with a headcount of 1,001-5,000 employees. The company designs, develops, manufactures, and services drilling and recovery equipment for the upstream oil and gas industry, organized into eight product platforms: conventional drilling and recovery equipment (OCTG, wellhead and X-mas tree, pumping units, sucker rod pumps, pressure vessels, and downhole tools); thermal recovery systems (steam boilers, thermal wellheads, vacuum insulated tubing/casing, and injection-production pumps); anti-corrosion and anti-abrasion products (HDPE/EXPE liner tubing, epoxy resin coated tubing, coated sucker rods, plated tungsten alloy tubing, anti-H2S equipment); multiphase flow meters; mechanized automated workover rigs; tertiary/EOR equipment (polymer injection, microbial displacement, modular mobile profile control); drilling and completion tools (liner hangers, centralizers, packers); and engineering, installation, and maintenance services. Underlying technology spans proprietary materials (a UHMW-PE EXPE liner tubing formula first introduced in China by Shengji in 2003), high-spec mechanical design (equipment rated to 20,000 psi and 390°C), and intelligent control systems enabling remote monitoring.

The business model is direct B2B enterprise sales: equipment is highly customized per oilfield requirements, sold via quote-based engagements with technical sales engineers, supported by eight global subsidiaries and regional sales contacts. Revenue streams include one-time hardware sales (drilling and recovery equipment), recurring steam injection services (330,000 tons cumulative since 2011), and engineering/maintenance services for installation, commissioning, and offshore platform upkeep. The customer base is concentrated among major international oil companies and national oil companies — including CNPC, Sinopec, CNOOC, Shell, Chevron, PDVSA, Schlumberger, Halliburton, NOV, and ONGC — with documented deployments in Bahrain (Tatweer), Kazakhstan (COIC, Caspian Sea), Venezuela (MPE3), and the Sichuan Basin (Shell China). The company maintains an unusually comprehensive certification stack (API 5CT, 6A, 11AX, 11E, 16A, Q1; ISO 9001/14001/45001; ASME S/U; CE; multiple DNV PR2 ratings), holds more than 100 patents in thermal wellhead and X-mas tree technology, and conducts R&D in partnership with China University of Petroleum and more than 10 research institutes.
