KOSUN Machinery

What KOSUN Machinery does

KOSUN Machinery Co., Ltd. (Xi'an KOSUN Machinery Manufacturing Co., Ltd.) is a privately held Chinese manufacturer of solids control and drilling waste management equipment for the oil and gas industry, founded in 1992 and headquartered in Xi'an with 251–500 employees. The company designs, manufactures, and integrates modular solids control systems (including Arctic variants for -40°C operation and Mobile skid-mounted variants), core separation equipment such as shale shakers, DC Series and Black Rhino decanter centrifuges, VC700 vertical cuttings dryers, mud cleaners, desanders, desilters, vacuum degassers, and centrifugal and submersible pumps, plus drilling waste management systems, HDD horizontal directional drilling mud recovery systems, TBM tunnel boring slurry treatment systems, and supporting accessories (shaker screens, centrifuge drums, hydrocyclones). Technology differentiation rests on purpose-engineered mechanical separation — for example, vertical cuttings dryers achieving oil-on-cuttings below 5% and Hi-G dryers reducing liquid/oil content to about 10% (w/w) — and the Black Rhino premium line targeted at North American and European specifications.

KOSUN makes money primarily through one-time equipment sales to oilfield operators and drilling contractors, supplemented by OEM production for Chinese drilling rig builders (Sichuan Honghua, Shandong Kerui, Yantai Jereh), equipment leasing under both dry-lease and wet-lease (with operators) terms, and professional services including operator training, equipment maintenance, and technical support. Revenue is quote-based and not publicly disclosed. The company reaches customers through a multi-channel motion: direct enterprise field sales via global offices, major industry exhibitions (CIPPE in Beijing, NEFTEGAZ in Moscow), an Alibaba storefront for SMB reach, and a network of country-level agents.

The company's served market is oil and gas drilling (its primary vertical) plus secondary use cases in HDD trenchless construction, TBM tunneling, and environmental remediation (via the KOSUN ECO sub-brand). Named anchor customers include CNPC, Sinopec, and CNOOC in China, Russia's Lukoil, and Oman Petroleum Projects. Internationally, KOSUN operates wholly-owned subsidiaries and branches in Kazakhstan (Aktobe factory since 2008, first overseas branch), Russia, the United States, and Indonesia, with products recognized in over 60 countries and certified to API, ISO, ISO14001/ISO18001, CE, and Russian export standards.
