U.K.-headquartered Hurricane Energy said the Lincoln Crestal well off the Shetland Islands has produced oil to the surface, but information on initial well results have not been released.

Responding to speculation about a flare on the Transocean drilling rig, the company confirmed in a news release that a drillstem test at the well, also known as 205/26b-14, produced oil to the surface, which resulted in a flare. Hurricane said the well was shut-in to enable a planned pressure buildup test.

The company said it plans to update the market on initial well results, including flow rates and oil type, after the testing phase is complete.

Lincoln Crestal is the second of three wells planned for 2019 as part of a work program for the Lincoln and Warwick assets with partner Spirit Energy.
