Serinus Energy announced on 15 July 2021 that the Sancrai-1 exploration well had discovered gas. Continuous formation gas shows were recorded over 20 metres of gross pay over four sand intervals from the measured depths of 855 metres to 875 metres. At this drilling interval the measured total gas ranged from 5.5% to 11.1% with an estimated average porosity of between 23% and 27%. Open-hole petrophysical analysis undertaken during the drilling operations further confirmed this gasbearing Pliocene sand zone.

The Company subsequently perforated the well in three zones to test the Pliocene sand zone prior to completing the well. However, the testing programme was unable to record the flow of gas in the selected zones. The Sancrai-1 exploration well will be suspended pending further technical studies to better understand the Sancrai structure and evaluate the options available, given the high total gas readings during drilling.
