Total and Apache have made a material oil discovery with the Maka Central-1 well on Block 58 offshore Surinam, in Guyana.

The Maka Central-1 well was drilled by a water depth of about 1,000 meters and encountered more than 123 meters net pay of high-quality light oil and gas rich condensate net pay, in multiple stacked reservoirs in Upper Cretaceous Campanian and Santonian formations, according to Total.

The companies will conduct further drilling and testing will be carried out to appraise the resources and productivity of the reservoir.

“We are very pleased with this first significant oil discovery, made just after our entry into Block 58. The result is very encouraging and proves the extension of the prolific world-class Guyana Cretaceous oil play into Surinam waters,” said Kevin McLachlan, senior vice president Exploration at Total. “We are optimistic about the large remaining potential of the area still to be discovered and will test several other prospects on the same block.”

The Maka Central-1 exploration well was drilled by Apache as operator with 50 per cent working interest and with Total as the JV partner with 50 per cent working interest.

“We are very pleased with results from Maka Central-1. The well proves a working hydrocarbon system in the first two play types within Block 58 and confirms our geologic model with oil and condensate in shallower zones and oil in deeper zones. Preliminary formation evaluation data indicates the potential for prolific oil wells. Additionally, the size of the stratigraphic feature, as defined by 3-D seismic imaging, suggests a substantial resource,” said John J. Christmann, Apache CEO and President.

“Block 58 comprises 1.4 million acres and offers significant potential beyond the discovery at Maka Central. We have identified at least seven distinct play types and more than 50 prospects within the thermally mature play fairway. In partnership with Total, we look forward to advancing both exploration and development of discoveries on the block,” Christmann added.

The next exploration well will be drilled on the Sapaka West-1 prospect and the operatorship will be transferred to Total after completion of a third exploration well.
