The Norwegian Barents Sea could hold 2.8 billion standard cubic meters (Bscm) oil equivalent (17.6 billion barrels), including 1.4 Bsmc to the southeast of the Svalbard archipelago, the country’s oil regulator said on April 25.

Seven years since its last assessment, additional drilling and data show the shale plays outshine the Marcellus and Utica, both of which were last assessed at the beginning of the decade.

 Reservoir characterization project shale results

Students at the Colorado School of Mines discussed promising results from a Wattenberg Field study area at the Reservoir Characterization Project spring meeting in Golden, Colo.

The find confirms the upside for the field “in the order of 10 to 30 MMboe,” Lundin Petroleum said in a news release.

As part of a day of presentations to analysts and investors, Hurricane said it had upgraded its recoverable resource estimate for the Lancaster Field to 593 million barrels from 200 million in a 2013 assessment.

The Snoek well, southeast of the Liza discovery, hit high-quality oil-bearing sandstone reservoirs, the company said.

Earlier this month the major said it had found “meaningful” reserves of oil offshore Mexico after becoming the first international oil company to drill a well in the country following a 2013 reform to open up the sector to investors.

Hurricane Energy’s Halifax well has encountered a hydrocarbon column of at least 1,156 m (3,792 ft), supporting its view that the prospect is linked to the Lancaster Field to form a single large hydrocarbon accumulation, the company said in a news release March 27.

The company plans to perform a three- to six-month extended production test starting in third-quarter 2017, following the completion in April of a light oil resource volume assessment, to help determine the commerciality of the discovery.

The first DST flowed from an 18 m interval at a maximum rate of about 4,500 barrels of oil per day on a 60/64-in. choke. For the second DST, an additional 8.5-m zone was added, and the well flowed at a maximum rate of 4,200 bbl/d.

To better gauge resource potential, ExxonMobil said the discovery is being evaluated with two sidetracks drilled. A well test is underway.
