About 400 employees work in the company, of whom 62 have university-level education and 100 have pre-university education. During the past 32 years of operations, exploration has continued with 20,000 km of seismic line geophysical investigation, identifying 21 prospective structures for further exploration and deep drillings. A total of 218 deep drill-holes and 171 structural holes have been drilled, resulting in the discovery of 19 oil fields, 10 of which are commercially significant. The company estimates a 7.9 million tons potential production from existing wells. In 1990, test oil production was started from separate wells and up to 1st January 1996, 0.46 million tons of oil had been recovered. Starting in 1996, AB Geonafta has carried out oil sales in Lithuania and oil exports were started in 1995. Oil exploration activities are performed in the Plunge Licence Area. On special orders, drilling operations are carried out by the company to investigate the reserves of geothermal energy in Devonian and Cambrian water-bearing horizons. Sealed structures suitable for gas storage are explored and drilling is begun.

In 1993-95, two joint ventures with foreign partners, UAB Genciu Nafta and UAB Minijos Nafta, were established for oil prospecting, exploration and production in the awarded Licence Areas.

At present AB Geonafta carries out the following activities:
