Anadarko nets second Mozambique discovery
Anadarko’s latest exploration well off Mozambique has found oil in the Ironclad structure.
LONDON -- Anadarko’s latest exploration well off Mozambique has found oil in the Ironclad structure.
According to partner Cove Energy, this is the first documented discovery of liquid hydrocarbons offshore East Africa. Ironclad-1 was drilled by the Belford Dolphin 110 km (68 mi) south of the partners’ Windjammer gas discovery. The aim was to evaluate the potential of an extensive Cretaceous deepwater fan complex comprising two lobes in the southern part of the permit.
Cove says the well penetrated 38 m (124 ft) net of oil and gas-saturated sands in the upper fan lobe. Oil was confirmed by geochemical analysis of rotary side wall cores extracted from the well bore. There were also substantial gas shows throughout the drilled Cretaceous section. The well was drilled to a TD of 5,304 m (17,519 ft), after intersecting a total of 205 m (672 ft) of Cretaceous age sediments.
Future analysis will focus on delineating areas likely to have good reservoir porosity and permeability, allowing commercial exploitation.
The rig will now transfer to a location east of Windjammer to drill the Barquentine prospect, an operation expected to take around six weeks. Thereafter, the partners will look to drill at least two more exploratory wells.
Cove’s CEO John Craven said of the result: “This is very promising not just for the Cretaceous fan systems, where over 80 sq km of closure have been mapped, but for additional nearby prospects already identified elsewhere in the Offshore Area 1 block.”
