Te Upper Bampo limestone formation has been tested over the interval 7785 feet true vertical depth (TVD) to 7853 feet TVD and has flowed gas at a rate of 25 million scfd through a 52/64 inch choke. Initial sampling indicates that the gas contains approximately 15 per cent carbon dioxide. Te gross resource estimate for the Matang structure remains in line with the pre-drill estimate of 100-400 billion cubic feet (Fig. 1). “We are pleased that this successful well test has confirmed Matang as an important discovery coming as it does on the back of exploration successes in the UK and Norway,” noted ceo Simon Lockett.
Lockett was referring to the successful well test of the Luno II discovery on PL 359 in the southwestern flank of the Utsira High in the Norwegian North Sea (Premier equity 30 per cent). Te production test achieved an average flow rate of 2044 barrels of oil per day of good quality (36 degrees API) crude oil through a 48/64 inch choke, with a gas to oil ratio of 1012 scf/barrel. Premier estimates gross resources across the Luno
II structure to be in the range of 75-130 million barrels of oil equivalent (mboe) of which approximately 80 per cent are liquids. An additional 10-40mboe has been mapped immediately North of the discovery in a low risk Triassic prospect. Further appraisal work is planned by the joint
venture partnership prior to making development decisions. In a third announcement, Premier says that oil
production from the Huntington field in the UK Central North Sea commenced on 12 April. After an initial ramp up period, the field is expected to produce 25,000-30,000boe/d (gross). “Tis marks the first of four UK North Sea
projects from our development portfolio which will come on-stream over the next few years. We look forward to the field making a significant contribution to our worldwide production and cash flow growth,” commented Lockett. Finally, Irish oil and gas exploration and appraisal company Providence Resources has confirmed that drilling activities have now commenced on the 44/23-1 Dunquin exploration prospect in Frontier Exploration Licence (FEL) 3/04, off the west coast of Ireland. ExxonMobil Exploration and Production Ireland
(27.5 per cent interest) operates FEL 3/04 on behalf of its partners, Eni Ireland
(27.5 per cent interest), Repsol Exploracion Irlanda (25 per cent interest), Providence Resources (16.0 per cent interest) and Sosina Exploration (4.0 per cent interest). Drilling operations are expected to take several months to complete using the Eirik Raude semi- submersible drilling unit. ●
