Maurel & Prom : Positive Technical Results in OMTI-1 in Gabon

PARIS - Drilled on the north of Onal in Gabon, the OMTI-1 well, reached the basement at a depth of 2 203 m. Between 1 300 and 2 100 m, it encountered 500 m cumulated of good quality reservoirs, 85 m from which put in evidence oil saturation. Samples have been taken and show a 38degrees API oil.

The well is currently stopped until technical solutions are available for testing, owing to the salt water content. At this stage, no conclusion may be reached about the commercial discovery.

These results confirm the potential of the north part of the Omoueyi Permit (Maurel & Prom operator, 100%) and reinforce the Group to continue exploration in this zone with the drilling of OMSN-1 well. The drilling will be conducted in the next days to be concluded in mid-October
