UAB Minijos Nafta of Lithuania’s Skomantai-1 well on the Gargzdai license onshore Lithuania found oil with subcommercial porosity in Cambrian sandstone and logged a thick shale section overlying the Cambrian and will be suspended for future work on the shale section.

Total depth is 2,431 m. The rig is moving to another location on the license to drill a sidetrack in the Cambrian sandstone, said Tethys Oil AB, which has a 25% indirect interest in the license through an agreement with Odin Energi AS.

Extensive data were gathered on the shale section. Electric logs were recorded and seven cores with a total combined length of 63 m were taken. The cores are being sent to a laboratory for analysis of various properties, including natural fracture, induced fracturing potential, porosity, permeability, source rock quality, and maturity.

The Gargzdai license produces more than 600 b/d of oil. In addition to Gargzdai, Tethys holds in Lithuania interests in the nonproducing Rietavas and Raiseiniai onshore licenses.
