Deb 15 well located in the Debeslavetska Exploration licence spudded-in on 28th November 2014 and drilling down to 404m was completed on 26th December 2014. The main targets in this unexplored area were initially the productive levels in the Badenian sequence (levels from B1 to B4) and possible sandy levels in the Cretaceous. The trapping mechanism in the Badenian is mainly stratigraphic, potentially in combination with structural pinching out forms, where sand levels are encompassed in a shale sequence.

Analysis continues but so far the results suggest that the level B1, where the biggest DHI and AVO anomaly was highlighted, was not encountered due to the sub-optimal well surface location (driven by logistics due to temporary moratorium on industrial uses of agricultural areas), while B2 was found reduced and truncated against the erosional channel surface running in the northern part of the field, probably just in opposition to the Cretaceous limestone. The B3, B4 and B5 intervals were found to be overlapping with water-bearing Cretaceous limestone, encountered earlier than forecast.
