Chariot Oil & Gas Limited announced that its wholly owned subsidiary, Enigma Oil & Gas Exploration (Pty) Limited, has commenced drilling the first well, 1811/5-1, of its 4 to 5 well drilling program offshore Namibia. Drilling operations began this morning on the Tapir South prospect using the Maersk Deliverer (UDW semisub) drilling rig, with Chariot as Operator.
The prospect has a 25 percent Chance of Success and a mean un-risked prospective resource potential of 604 million barrels of oil. In the event of success, the results of this well will significantly increase the Chance of Success on certain of the Company’s other prospects within the Tapir Trend.
Tapir South (1811/5-1) will be only the second well ever to be drilled in the Namibe Basin. It is located 49.7 miles (80 kilometers) offshore Namibia in the Company’s northern block 1811A, in which Chariot has a 100 percent equity interest. The well is being drilled to an estimated total vertical depth subsea of 16,732 feet (5,100 meters) and, as announced following the Placing of March 20, 2012, this will now include extended drilling time to ensure that one of the deeper identified targets is drilled and fully evaluated. This deeper target is believed to be a carbonate section, age equivalent to the reservoir in recent sub-salt discoveries in the on-trend Kwanza basin offshore Angola. The drilling and logging operations are expected to take approximately 70 days and a further announcement will be made when the well results are known.
The Tapir South prospect is part of the Tapir Trend where three prospects have been identified on a large ridge formed by a rotated fault block containing the potential carbonate target, draped by deep marine sediments with turbidite sandstone levels forming a stack of overlying targets. Tapir South is the southernmost of three culminations on the ridge and forms a focal point for charge migration from an adjacent basin in which excellent oil prone source rocks are believed to be present and currently generating oil.
The second well to be drilled in the Chariot exploration program, Kabeljou (2714/6-1), targeting the Nimrod prospect is now likely to spud earlier than previously reported. The Operator has informed Chariot that it now expects to secure a drilling unit in 3Q 2012.
“We are very pleased to announce the spud of our Tapir South well in the northern license area which marks that start of a 4-5 well drill program running through to the end of 2013. The results of this first well will be invaluable to furthering our knowledge and understanding of the Namibe basin. Owing to the additional funding raised last month we can now fully explore the deeper targets within the prospect and we look forward to updating the market with the well results in due course,” commented CEO Paul Welch.
