Jereh Group

Jereh Group, formally known as Yantai Jereh Oilfield Services Group Co., Ltd., is a Chinese industrial group headquartered in Yantai, Shandong. The company is principally associated with oilfield services and the manufacture of equipment used in drilling, well stimulation, production, fluid handling, and related energy operations. It is also known by the shorter names Jereh Oilfield Services and Yantai Jereh. The group’s public-market identity is linked to Shenzhen Stock Exchange ticker 002353. The business began in 1999, when Sun Weijie, Wang Kunxiao, and Liu Zhenfeng established Yantai Jereh Equipment Co., Ltd. The original activity centered on trading imported mining accessories rather than the broad industrial portfolio associated with the group today. Jereh subsequently expanded from equipment distribution into engineering, manufacturing, and oilfield-service capabilities. This shift gave the company a more integrated role in the energy sector, allowing it to supply equipment and services to operators and contractors rather than functioning solely as a trading intermediary. Jereh established American Jereh Corporation in 2008, marking an important step in its international development. Its overseas work has included equipment and service activity in markets outside China, including the United States, Kuwait, and Venezuela. The company’s equipment entered the U.S. market as early as 2007 through an automated slurry mixing skid, illustrating the group’s effort to commercialize specialized oilfield systems internationally. Jereh has been described as one of China’s largest domestic oilfield-equipment and service providers, with a particularly strong position in shale-drilling equipment. The company became publicly listed on the Shenzhen Stock Exchange in 2010. Public ownership provided a platform for continued investment in equipment manufacturing, international projects, and adjacent environmental and energy technologies. Its later development has not been limited to conventional oilfield services. In 2015, Jereh established Jereh Environmental Technology Corporation, whose activities focus on oilfield-sludge treatment, sludge dewatering, and soil remediation. This expansion connected the group’s energy-sector expertise with environmental management and industrial waste-treatment needs. In 2021, Jereh established Jereh New Energy Technology Co., Ltd. to enter the anode-material field for lithium-ion batteries. The move reflects a broader diversification strategy in which an established oilfield-equipment group seeks opportunities in environmental technology and new energy while retaining its core industrial identity. Jereh’s business therefore spans both conventional energy infrastructure and selected technologies associated with industrial remediation and energy transition. International projects have included a contract awarded by Kuwait Oil Company for Jurassic Production Facilities 5. The project concerns testing, processing, and handling wet and sour hydrocarbon well fluids from Kuwait’s Jurassic fields. In Venezuela, Petróleos de Venezuela ordered 970 sets of Jereh oilfield equipment in January 2013 for the company’s first oil and gas service business, with the reported order value stated in the reference material as US$178 million. These projects demonstrate Jereh’s participation in technically demanding production environments and its ability to supply equipment at substantial scale. Today, Jereh Group is best understood as an industrial and energy-services brand rather than a consumer-facing name. Its positioning rests on engineering capability, equipment manufacturing, project execution, and international service delivery. The group’s core reputation remains tied to oilfield equipment and services, while environmental treatment and lithium-battery anode materials represent important adjacent areas of development.

Jereh Group traces its origins to 1999, when Sun Weijie, Wang Kunxiao, and Liu Zhenfeng founded Yantai Jereh Equipment Co., Ltd. in Yantai, China. The initial business traded imported mining accessories. Over time, the company moved beyond trading and developed manufacturing and service capabilities for the oil and gas industry, eventually becoming known as Jereh Oilfield Services and later as Jereh Group. The group’s expansion was driven by the growing demand for specialized drilling and production equipment. Jereh developed a position in oilfield equipment and became particularly associated with shale-drilling systems. Its internationalization began before the creation of its American subsidiary: an automated slurry mixing skid entered the U.S. market in 2007. In 2008, the company formally established American Jereh Corporation, providing a platform for overseas commercial activity. Jereh became listed on the Shenzhen Stock Exchange in 2010 under ticker 002353. The listing marked a transition from a privately established equipment company into a publicly traded industrial group. Its international project portfolio subsequently included work in the Middle East and Latin America. A notable Kuwait project involved a contract from Kuwait Oil Company for Jurassic Production Facilities 5, covering the testing, processing, and handling of wet and sour hydrocarbon well fluids from Jurassic fields. In Venezuela, PDVSA ordered 970 sets of Jereh oilfield equipment in January 2013 for its oil and gas service business. The company diversified into environmental services in 2015 by establishing Jereh Environmental Technology Corporation. This business focused on oilfield-sludge treatment, sludge dewatering, and soil remediation, extending Jereh’s industrial capabilities into pollution control and environmental management. The move was strategically related to the group’s oilfield background because drilling and production generate complex liquid and solid waste streams requiring specialized treatment. In 2021, Jereh created Jereh New Energy Technology Co., Ltd. to enter the lithium-ion battery anode-material market. This initiative broadened the group’s portfolio beyond fossil-fuel infrastructure and reflected the increasing importance of battery materials and energy-transition technologies in China’s industrial economy. Jereh’s development can therefore be divided into several stages: an initial mining-accessories trading business; a transition into oilfield equipment and services; international expansion through overseas subsidiaries and projects; diversification into environmental treatment; and entry into lithium-battery materials. The group remains principally identified with oilfield equipment and services, but its corporate structure and investment direction encompass a wider range of industrial and energy technologies.
