Tethys Oil reports successful exploration well onshore Lithuanian
STOCKHOLM, Sweden -- Tethys Oil has completed the drilling of the Tidikas-1 exploration well on the Raseiniai license onshore Lithuania, the Stockholm-based company announced Wednesday.
The well encountered a combined oil column of almost 50 m in two different limestone formations and flowed oil to surface during drill stem tests. The well will now be put on a long-term production test.
Tidikas-1 was drilled vertically to the Cambrian sandstone, at a measured depth of 1,413 m, and cores were taken from Silurian and Ordovician limestones, marl and dolomites. Tidikas-1 was the second well drilled in 2015 on the license.
The Bedugnis-1 well, which was completed in August, was drilled vertically to a total measured depth of 1,067 m and recorded oil shows while drilling, but no oil flowed to surface. Both wells were targeting Silurian reefs and carbonate features mapped by an 80 km2 3D seismic study completed in 2014.
Active petroleum system
“We are quite encouraged by the well results so far. There are now clear indications that an active petroleum system exists within the Raseiniai license. We are looking forward to the results of the long term production tests from Tidikas-1 and the analysis of the cores from both Tidikas-1 and Bedugnis-1,” Magnus Nordin, managing director of Tethys Oil, said.
The location of further wells on the Raseiniai license will be determined after more information has been gained through the long-term production test of the Tidikas-1 well and the analysis of the cores.
The Raseiniai license covers 1,535 km2 onshore Lithuania. Tethys Oil has a 30% indirect interest in the license.
