On 27 November 2017, UAB Diseta, the sole operator of the Kudirka-Kybartai contract in the southern part of the country, finished drilling vertical appraisal Kudirka 1. The well was drilled to the final total depth of 774 m in the Silurian series. Subsequent tests over two intervals - 757-766 m and 757-774 m - yielded water and the well was abandoned. Kudirka 1 was started on 30 October 2017, using the LTO 600 drilling unit from LOTOS Geonafta. The well is located close to the border with the Kaliningrad district, within the Kirsiu Depression, tectonic unit of the Baltic Syneclise. The well had a planned final depth of 770 m, targeting the Upper Silurian reefal structure.
