In brief

On 13 August 2025, the Ukrainian government approved the tender terms, process and timeline for the two oil and gas areas in Western Ukraine, the Mezhyhirska (M) and Svichanska (S) blocks, located near the EU countries bordering Ukraine (Poland, Slovakia and Romania).

Resolutions of the Cabinet of Ministers of Ukraine Nos. 975 and 982 replaced the April 2025 approvals for the tenders of these two blocks. The tenders, framed under the provisions of the PSA Law and the Agreement between the Government of Ukraine and the Government of the United States of America on the Establishment of a United States – Ukraine Reconstruction Investment Fund ("Minerals Deal"), appear to be among the first steps Ukraine has taken in implementing the Minerals Deal.

Production sharing agreement (PSA) bids must be submitted independently for each block. Bids will be assessed separately for each block according to a set of detailed criteria. The most importance will be given to commercial proposals as to the production sharing split, minimum work program, experience in similar projects and industry track record, etc. The tender participation fee will be approximately USD 12,000.

The key baseline parameters for each tender are summarized in the table below.
