So far, an oil column of about 70mt with approximately 38mt of net pay was encountered in carbonate reservoirs in the Albian section. Thermobaric effects associated with volcanism in the area contributed to optimize the permo-porosity properties of the reservoirs.

The drilling in the Albian section is still in progress and the well OGX-6 will be drilled up to a final depth of approximately 3,600mt, the company said.

More than 50mt of reservoir rock cores have been collected at this well in order to analyze characteristics of the reservoirs and to aid in the appraisal and development of future projects. These sample cores and logs indicate a strong correlation between the Albian reservoirs of OGX-6 (Etna), OGX-3 (Waimea), and OGX-2 (pipeline). The Etna prospect is located 8.5km to the northeast of the Waimea prospect and is structurally indicates 400mt above the Waimea reservoir.

Paulo Mendonca, general executive officer of OGX, said: “Our review of this data indicates that these accumulations may be connected and that the recently discovered oil province may, in fact, extend to the north of the BM-C-41 block, confirming its very significant petrolific potential. New data will be collected and new wells will be drilled in order for us to better map the prospects identified in this province.”

The OGX-6 well is located in the BM-C-41 block and is situated approximately 82km off the coast of the state of Rio de Janeiro at a water depth of approximately 137mt.
