On 28 December 2017, UAB Diseta, the sole operator of the Kudirka-Kybartai contract in the southern part of the country, finished drilling vertical new-field wildcat Vilkupiai 1. The well, drilled to the final depth of 805 m in the Minja Formation (lower part of the Pridoli Stage of the Late Silurian period), was tested over three horizons â all of them yielded minor oil shows and the well was suspended. Vilkupiai 1 was started on 1 December 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 was targeting the Upper Silurian reefal structure (primary target) at a depth of 761 m and, optionally, the cambrian sandstone series at a planned depth of 1.238 m. Vilkupiai 1 was terminated after reaching the primary target.
