Exploration and Production

Ever since crude oil was first discovered in Slovakia’s Záhorie region, geological data has been acquired and researched and much progress has been made in gaining technical knowledge and experience. These are the foundations for NAFTA’s operations, forming a critical part of its unique know-how and behind its success in geological and drilling projects. We see the specific use of geological data obtained, for example, in understanding of the earth’s geological composition or in searching for sources of geothermal energy.

NAFTA is currently the most important player in Slovakia’s oil and gas exploration and production sector.

We have long been active mainly in the Vienna Basin, Danube Lowland and the Eastern Slovak Lowland, where the country’s most important regional hydrocarbons are located. In order to continue production and remain strong in this specific sector, NAFTA has expressed interest in concentrating in future on exploration in other regions in Slovakia, too.

The company’s main priority in everything we do is operational safety and minimizing the impact of our activities on the environment and local communities.

What exploration is NAFTA doing?

The first step is exploration work, mainly taking geophysical 2D/3D seismic measurements. Results from these measurements provide knowledge about the geological structure of the rock and soil environment, which can also be used for other purposes, such as searching for sources of geothermal energy and drinking water.

Based on the interpretation of these seismic measurements, the next step is to drill exploration wells.

What are the benefits from exploration?

  • Local sources of natural gas
  • Cooperation in identification of drinking water sources
  • Cooperation in identification of geothermal water sources
  • Collaboration in various municipal projects

Attention centered on the environment

NAFTA takes a responsible approach toward shutting down sites of our operations in Slovakia, including wells, drilling centers and parts of them through cleanups, biological reclamation and reintegration into the surrounding nature. 

NAFTA operated a mud pit in Moravany between 1984 and 2006, where production waste from its drilling was deposited. Subsequently, we embarked on successfully closing it and reintegrating the land into the countryside. Work to close down the mud pit was completed in July 2019.

Exploration projects in Slovakia are bringing also international cooperation and investments. We are partnering in the Trnava and Topoľčany Exploration areas with Vermilion Energy and in the Eastern Slovak Lowlands with Aspect Energy.

NAFTA is using its many years of hydrocarbon exploration and production experience even beyond Slovakia’s borders.

Its successful start of foreign activities began with the company entering into Ukraine, where it operates since 2016.

NAFTA has been slowly developing in the country and engaging in public tenders. For instance, last year we were successful n a tender for two PSA projects - Grunivska and Okhtyrska. Both licenses enabled us to obtain new exploration and production opportunities in Ukraine.

NAFTA is constantly seeking further foreign activities and joint ventures where it could apply the geological knowledge and expertise it has gained from many years of experience. We are focusing on opportunities in Central and Eastern Europe as well as in the Balkans.
