Enquest has applied to the UK authorities to drill a single well into an undeveloped fault block at its Don field in the northern North Sea to move ahead with a development that the independent operator is calling Don North East.

EnQuest said it is planning to start drilling a single well — 211/18a-JB — which is classed as an exploration/development well in about May 2020, with first oil expected in the third or fourth quarter of 2020.
