Transgex SA is a Romania-based energy and geological engineering company primarily engaged in the exploration, exploitation, and commercial distribution of geothermal resources, as well as specialized drilling and technical services. Founded in 1959 and headquartered in Oradea, Bihor County, Romania, the company operates across the Western Plain of Romania, serving municipal district heating networks, industrial clients, commercial facilities, and residential consumers. Transgex SA organizes its core operations into geothermal energy supply, well drilling, and geological engineering services. The company's portfolio of products and services includes the extraction and distribution of geothermal water for direct space heating and domestic hot water preparation; the operation and maintenance of geothermal production wells, reinjection wells, and secondary heat-exchange substations; deep and medium-depth well drilling services for energy and hydrogeological applications; hydrodynamic testing, flow rate monitoring, and well logging; comprehensive hydrogeological and geophysical studies; geological reservoir modeling and data processing; and turnkey engineering, procurement, and construction (EPC) solutions for geothermal heating infrastructure, alongside greenhouse agricultural heating operations utilizing low-enthalpy geothermal energy. In recent strategic developments, Transgex SA entered into an agreement in 2026 to divest its oil and gas drilling business line—including its Bentec 350 AC drilling rig, associated field equipment, specialized personnel, and active drilling service contracts with operators such as SNGN Romgaz SA and OMV Petrom—to Foraj Sonde Videle SA for 9.5 million euros. This divestment marks a major strategic realignment aimed at phasing out conventional hydrocarbon drilling to concentrate capital and operational resources exclusively on renewable geothermal water exploitation, sustainable thermal energy supply networks, and green transition initiatives across Bihor and Satu Mare counties.
