Positive exploration results for Niembi-1D (EZANGA)

ONAL's first horizontal well is a success (EZANGA)

Maurel & Prom announces two positive results for the Ezanga permit as part of the new exploration and production sharing contract signed with the Gabonese Republic in February 2014.

Niembi-1D - EZANGA - Exploration, 100%, MAUREL & PROM operator

The exploration well Niembi-1D (ENZI-1D) was drilled 6 km south of the fault of the ONAL field in the huge, unexplored sedimentary basin that is forming downstream of the field.
The well reached its final depth of 2,425 m in the metamorphic sourcerock.
Reservoirs of the upper and lower Kissenda were recorded in this well and electric well logs indicate that they are all saturated in hydrocarbons. The fluid gradients obtained from pressure meters confirm that it is crude oil. The combined heights of the Kissenda reservoirs is 17 metres, with 15-20% porosity.
A 7" tube will be sunk and cemented into place to enable production tests to be conducted. Once Niembi-1D has been completed, the drilling rig will be moved to the location of the next exploration well, Mabounda-1, to continue with the analysis of the reservoirs and evaluation of the potential offered by this new area.

Drilling EZANGA's first horizontal well - Production, 80%, Maurel & Prom operator

Maurel & Prom drilled the 1502-H well in the Grès de base formation in the ONAL field.
The drain is located at a depth of 945 m over a horizontal length of 268 m, 185 m of which is in the reservoir.
Production tests conducted on the well showed a steady oil flow rate of 750 bpd. Full-scale production at this well is set for mid-December 2014.
The success of this horizontal well, the first in a series of seven wells planned for 2015, and the work being done to improve the efficiency of the water injection programme, both contribute to measures put in place to considerably increase production from these fields.
