Faroe Petroleum Plc said Sept. 17 it made an oil discovery in the main bore of the Boomerang exploration well in the Norwegian Sea.

The exploration well (6406/12-4) was drilled on the Halten Terrace, about 33 km (21 miles) southwest of the Njord Field and 1.7 km (1 mile) southeast of the Pil discovery well (6406/12-3 S).

The objective of the main wellbore was to test the hydrocarbon potential in the southwest segment of the Upper Jurassic Boomerang prospect close to the Pil discovery. The primary reservoir targets with upper Jurassic reservoirs anologus to the Pil, Bue and Draugen field reservoirs.

The main wellbore encountered a 26 m (85 ft) gross Upper Jurassic Intra-Spekk/Rogn sandstone. Preliminary analysis from wireline logs, pressure and fluid sampling shows that the well has encountered sandstones with good reservoir properties and moveable oil. Preliminary estimates of recoverable volumes in the discovery range between 13-31 MMboe.

The secondary objective of the main wellbore was to investigate the extent, thickness and properties of Upper Jurassic Melke reservoir rocks, as well as the extent and level of the Pil oil-water contact. Hydrocarbons were confirmed above the Pil oil-water contact in an 80 m gross interval of Melke age sandstone of varying reservoir quality and the main Pil reservoir sandstone was encountered within the water let, as planned, giving important appraisal information for the Pil development.

The exploration side-track 6406/12-4 A was drilled into the southern segment of the Boomerang prospect with the main objective testing the hydrocarbon potential in the Upper Jurassic sandstone of the Spekk and Melke formations. The well encountered about 530 m gross thickness of Jurassic sandstones with poor reservoir quality and reached a total vertical depth of 3,800 m (12,467 ft) below sea level. The well had indications of hydrocarbons but the presence of moveable hydrocarbons was not proven.

The Boomerang well will now be plugged and abandoned and the rig will be moved about 6 km to the northeast to drill the Blink prospect (6406/12-5 S). Blink is an independent structural and stratigraphic prospect. The well will target analogous Upper Jurassic reservoirs to Pil, Bue and Draugen.

The drilling campaign is being operated by VNG Norge AS (30%) using the Transocean Arctic semi submersible drilling rig with partners Spike Exploration Holdings AS (30%), Pure E&P Norway AS (15%) and Faroe (25%).
