The Mabounda-1 (EZMAB-1D) and Niembi-1 (EZNI-1D) exploration wells on the EZANGA permit in Gabon were drilled on independent structures to a total depth of 2,060 metres and 2,425 metres, respectively.

24 hour-duration tests were run on each of the two wells with the following positive results:

The Grès de base test on the EZMAB-1D well showed a stabilised eruptive flow of 1,002 bopd of anhydrous oil with a degree API of 28°. The surface pressure is stabilised at 9 bars.

The test at the Lower Kissenda summit on the EZNI-1D well showed a stabilised eruptive flow of 1,162 bopd of anhydrous oil, with a degree API of 35°. The surface pressure is stabilised at 40 bars. The other hydrocarbon impregnated reservoirs at the Upper Kissenda and at the base of the Lower Kissenda, with different pressure system, will be tested later.

These new oil discoveries made by Maurel & Prom in Gabon confirm the exploration themes in the sedimentary basin being carried out in the south-west part of the Onal field.

Maurel & Prom works on a project to connect the two wells to the Onal production centre located not far away and will present to the Direction Générale des Hydrocarbures the field development plan for the fields.

Maurel & Prom, the operator, owns 100% of the Ezanga exploration permit and 80% of the production licences. The state of Gabon owns 20% of the interests in these production licences.
