LONDON – The semisub Maersk Deliverer has started drilling the 1811/5-1 well on the Tapir South prospect offshore Namibia.
This is the second well ever drilled in the Namibe basin. The location is 80 km (49.7 mi) offshore in northern block 1811A.
The well is being drilled to an estimated TVD subsea of 5,100 m (16,732 ft). One of the deeper identified targets is thought to be a carbonate section, equivalent in age to the reservoir in recent subsalt discoveries in the on-trend Kwanza basin offshore Angola to the north.
Drilling and logging should take around 70 days.
Operator Chariot Oil & Gas (AIM:CHAR) assesses prospective resources at 604 MMbbl.
Tapir South is part of the Tapir Trend where Chariot has identified three prospects on a large ridge formed by a rotated fault block containing the potential carbonate target. This is draped by deep marine sediments with turbidite sandstone levels forming a stack of overlying targets.
The second well in Chariot’s exploration program, Kabeljou (2714/6-1), will target the Nimrod prospect. Operator Petrobras expects to secure a drilling unit in 3Q 2012.
