Bimini wildcat reaches total depth

Total depth: Apache-operated wildcat wraps drilling ops in GOM

Apache and Anadarko Petroleum have reached total depth on the Bimini exploration well in the Garden Banks area of the Gulf of Mexico.

Bimini, which is operated by Apache on a 50-50 stake with Anadarko, reached a permitted depth of just under 23,000 feet late last month, sources said. It was drilled with the Diamond Offshore semi-submersible Ocean Onyx in about 900 feet of water.

Industry chatter suggests the well did not make a commercial discovery, though early results are not clear. One source said Apache was "plugging" the well, though it was not known if the well would also be abandoned.

Apache did not comment, saying it generally announces well results with quarterly disclosures.

Anadarko also declined to comment, saying it does not plan to release results on individual wells, "whether they are discoveries or dry holes", until its quarterly update comes out.

Bimini, which was spud in January, had a pre-drill resource estimate of about 220 million barrels of oil equivalent, according to energy investment bank Tudor Pickering Holt. The well tested a Miocene-aged sub-salt three-way closure.

It was drilled in Garden Banks Block 213 in the Anadarko-operated Power Play field, not far from the US independent's Conger field and Baldpate compliant tower platform. The prospect was said to be on trend with the Llano and Cardamom fields to the south-west.

Anadarko had seen potential to tie back Bimini to existing infrastructure.

Apache announced plans last month to divest substantial portions of its US Gulf portfolio in an effort to focus more onshore. It sold minority stakes in the Anadarko-operated Lucius and Heidelberg developments as well as a number of exploration leases.

Bimini is one the company retained in the sale to Freeport-McMoRan. Apache acquired the prospect when it bought out Mariner Energy in 2009.
