UK-based explorer Ophir Energy has started drilling operations on the Padouck Deep-1 well on the Ntsina Block, offshore Gabon, using the Vantage Titanium Explorer drillship.
Padouck Deep-1 is the first well targeting the pre-salt play offshore in the North Gabon basin, although the play is regionally extensive elsewhere in Gabon and West Africa, said Ophir.
The prospect is estimated to contain mean recoverable resources of about 1billion bbl, with significant follow-on potential.
The well is in about 835m water depth and has a planned TD of 3500m (tvd subsea). Operations are expected to take about 45 days.
Ophir has a 40% operated interest in the block. Ophir’s share of the well cost is largely carried by partners Petrobras and OMV, subject to government approval of a farm-in by OMV.
Nick Cooper, CEO, said: “The Padouck Deep-1 well is the first of three potentially transformational wells being drilled back to back by Ophir in Gabon targeting substantial oil resources. Padouck Deep is one of two pre-salt wells that will be drilled in the current campaign where the total play potential is estimated at about 4billion bbl from currently defined leads and prospects.”
