Results from Cairn’s SNE-6 appraisal well offshore Senegal have confirmed connectivity with its SNE-5 well, proving oil of similar quality, the company said in a news release.

The gas find, located west of the Teranga discovery and south of Tortue, is estimated to hold 15 trillion cubic feet of natural gas.

The company said the latest independent analysis of reserves at the field showed 523 million barrels (MMbbl) of oil could be recoverable, more than double the amount assessed in 2013.

Anadarko, the operator, said the well hit 79 m to 110 m (260 ft to 360 ft) net of natural gas pay.

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.

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.
