Since October 1997, the exploration activity is carried out in 8 blocks located in Transylvania, Muntenia‑Oltenia and Moldova, subject to the Concession Agreement approved by Government Decision No. 23/2000.

Currently, exploration activities are performed under Addendum No. 6 (approved by GD No.1011/22.09.2021 to the Concession Agreement for petroleum exploration-development-production approved by GD No.23/2000, with a validity term of 6 years (10.10.2021 – 9.10.2027). The approved minimum work program includes 36 wells with a total length of 92,000 m and 1,000 km2 3D seismic for all eight blocks, with the total value of the program of USD 195 million.

Main exploration drilling works performed in 2023 are:

  • drilling exploration wells:
    - two wells are finalised, both in conservation, testing gas;
    - one well tested and abandoned after tests;
    - two exploration wells awarded by tender procedure and another six wells in progress to procure drilling works;
    - thirty four wells in various stages of preparation for drilling procurement;
  • ongoing procurement and processing of 3D seismic data for exploration-development-production blocks RG.01 Transilvania Nord and RG.02 Transilvania Centru, covering an area of approximately 700 km2.

Exploration works are designed and prioritised based on technical-economic principles, to increase the hydrocarbon resources and reserves portfolio and to maximise the potential of the eight exploration-development-production blocks licensed by ROMGAZ.

The table below shows the evolution of the reserves replacement ratio between 2013-2023:

2023 production

Reserves replacement ratio is influenced by the improvement of the final recovery factor, by promoting probable and possible reserves and by investments in the infrastructure necessary for streaming in experimental production of new exploration discoveries.
