Tap Oil Limited advises that the onshore exploration well, Mawar-1 in Block M, Brunei Darussalam spudded today.

Mawar-1 is the first well to be drilled in an initial two well exploration program in Block M, where Tap is the operator of the block. It is the first well to be drilled in Block M since 1988 and is the first well drilled by the Block M Joint Venture for the Brunei National Petroleum Corporation (PetroleumBRUNEI).

Tap Chief Executive Officer, Peter Stickland, said the Company has been looking forward to getting the bit in the ground and drilling our first well in Brunei, Block M.

'Mawar-1 has significant oil potential at low-to-moderate risk due to the offset well control and interpretation on modern 3D seismic data,' Mr Stickland said.

'Brunei's established infrastructure means Tap will be able to quickly monetise any commercial discovery,' he said.

The Mawar-1 prospect was identified as being prospective for oil during interpretation work on the 3D seismic data acquired by the joint venture in 2009. The prospect is a fault compartment identified within the Belait Anticline and pre-drill mapping indicates a prospect size up to nine million barrels of oil.

Given the drilling history within the Belait trend, the Mawar-1 well is considered to be low-to-moderate risk. The well is 30kms south of the giant Seria oil field, which includes an oil refinery and terminal and the Brunei liquefied natural gas (LNG) facility.

Mawar-1 is being drilled as a deviated well to test multiple sandstone objectives within the Mid-Late Miocene Belait formation. The well is designed to a total depth of approximately 1,300m below the drill floor.

The well is being drilled by the MB Century Rig 104 and is expected to take approximately 28 days to drill and evaluate on a trouble free basis. In the case of a discovery, the well is likely to be suspended pending testing by another rig designed for that purpose.
