    We implement a collection system and run processing plants, and we ensure that extraction processes are sustainable, safe, and transparent even before beginning operations, in line with the most stringent standards.
  • Production

    When the facilities are ready to begin extraction operations, our teams get to work in order to use the reservoir's resources to their full potential. In addition to extracting oil and gas, we constantly perform maintenance tasks and transport hydrocarbons under the strictest conditions.

Projects that guarantee sustainable growth

We have onshore and offshore projects in a total of 28 countries.
