According to partner Faroe Petroleum, main bore 6406/12-45 was drilled in the southwest segment of the Upper Bookmerang prospect, 1.7 km (1 mi) southeast of last year’s Pil oilfield discovery. It encountered a 26-m (85-ft) gross Upper Jurassic intra-Spekk/Rogn sandstone with good reservoir properties and moveable oil, thought to be in the range 13-31 MMboe.
Analysis confirmed hydrocarbons above the Pil oil-water contact in Melke-age sandstone, and the well also encountered the main Pil reservoir sandstone within the water leg, as planned, providing important appraisal information for the Pil development
A subsequent side-track, 6406/12-4A, was drilled into Boomerang’s southern segment, intersecting poor-quality Jurassic sandstone reservoir, but with no evidence of moveable hydrocarbons.
Both wells were on the Halten Terrace, 33 km (20.5 mi) southwest of the Njord field.
After completing P&A operations, Transocean Arctic will transfer 6 km (3.7 mi) to the northeast to drill the Blink (6406/12-5S) exploratory well, target Upper Jurassic reservoirs thought to be analogous to Pil and the nearby Bue and Draugen fields.
