The discovery of oil reserves in the Bashkirian was not included in the earlier resource and reserves review, as earlier exploration had aimed at the Bobrikovskiy and Tournaisian horizons.
The metamorphic clasts strongly resemble local basement rocks exposed as belts between conglomeratic domains in Isle Madame, indicating that these deeper crustal rocks were unroofed within the former basin in the late Tournaisian, resulting in redirected drainage patterns.
The well was drilled as a deviated directional oil production well for the Tournaisian reservoirs using the same technology as in side-tracked well 24.

The section was located on the northeastern margin of Laurussia during the late Famennian-Tournaisian and comprises the stratigraphical interval from the latest Famennian praesulcata Zone through the late Tournaisian crenulata Zone, being 16.5 m thick (Zhuravlev et al.
