Iran claims a major oil discovery in the southern part of the Caspian Sea. A semisub operated by Khazar Exploration and Production Co. drilled the well, intersecting a 24-30 m (79-98 ft) thick oil layer. Early estimates suggested 8-10 Bbbl in place.

East Africa

Operators have amassed three more potentially giant discoveries in the Rovuma basin/Rovuma delta play. Off Tanzania, BG Group/Ophir Energy notched a fifth successive deepwater gas find, and is testing a new play fairway in the deeper Cretaceous section. Mzia-1 in block 1 intersected two gas-bearing columns in stacked reservoir intervals holding potential resources of 3.5 tcf, with potential upside in an untested shallower potential reservoir interval. The location is 45 km (28 mi) offshore and 45 km (28 mi) from the median line with Mozambique, in a water depth of 1,639 m (5,377 ft).

Anadarko says its Golfinho discovery, 20 mi (32 km) northwest of its Prosperidade complex of gas fields in Area 1 off Mozambique, could hold 7-20 tcf recoverable. Gas was encountered in two Oligocene fan systems geologically distinct from the Prosperidade accumulations. The latest find is closer to land, (10 km/6.2 mi offshore), in 3,370 ft (1,027 m) of water. After completing the well, the drillshipBedford Dolphin was due to drill the Atum-1 prospect for the consortium.

Eni's run continues with Coral 1 in offshore Area 4, estimated to contain 7-10 tcf, pushing total Area 4 reserves to a potential 47-52 tcf. Coral 1 encountered 75 m (246 ft) of gas pay in Eocene sand, 26 km (16 mi) southeast of the Mamba South 1 discovery. Eni plans at least five more wells to delimit Area 4's resources.
