About the company:

Nanyang Erji Petroleum Equipment Group Co., Ltd. was originally established as Nanyang Petroleum Machinery Plant of Henan Petroleum Exploration Bureau of Sinopec Group (the former No. 2 Petroleum Machinery Plant of the Ministry of Petroleum Industry). On June 26, 2004, the company underwent a restructuring, converting from a state-owned enterprise to a limited liability company, and later transformed into a joint-stock company on January 18, 2016.

Nanyang Erji is a nationally recognized localization base for major technical equipment, a localization base for light oil drilling rigs, a national innovative enterprise, a high-tech enterprise, and a high-tech enterprise of the Torch Program. The company boasts several institutions, including the National Petroleum Vehicle Equipment Standardization Department, National Certified Enterprise Technology Center, Academician Workstation, and Postdoctoral Research Workstation.

Nanyang Erji’s product offerings include 12 series and over 200 varieties of drilling equipment, including truck mounted drilling rigs, skid mounted modular drilling rigs, tractor mounted drilling rigs, workover rigs, and logging equipment. In the 1990s, the company was at the forefront of the development of portable drilling equipment, characterized by rapid transportation and automation.

Nanyang Erji’s early development of a 3000m truck mounted drilling rig earned it the second prize of the National Science and Technology Progress Award. The company’s 4000m truck mounted drilling rig and 4000m trailer mounted drilling rig meet the high-end needs of users for large tonnage self-propelled drilling equipment and provide advanced equipment for industrial drilling.

The company is also committed to researching and developing unconventional oil and gas equipment and exploration and development equipment that meet the special environmental needs of oceans, deserts, tidal flats, rainforests, and low temperatures (polar regions). It continues to improve the mechanization and intelligence of its equipment. For example, Nanyang Erji has developed a full hydraulic coalbed methane drilling rig, a series of low-temperature drilling rig products that meet the environmental requirements of -45℃ to -60℃ and have been exported to high-end markets such as Russia and Canada, a small module helicopter hoisting rig for tropical rainforest environments, a car trough integrated rig, and a vehicle mounted (towed) rig without strings to meet the special customization needs of users.

Presently, while maintaining its leading position in the industry, Nanyang Erji is actively providing engineering technical services in oilfield drilling, cementing, logging, and other areas. The company aims to grow from a domestically advanced oil drilling and production equipment manufacturer to an international advanced oil and gas complete equipment system integration and service provider.
