Sept 24 (Reuters) - North Sea-focused oil producer EnQuest ENQ.L maintained its full year production forecast on Wednesday after reporting a first-half loss after tax, partly hurt by Britain's windfall tax and declining output.
The company posted a loss after tax of $173.5 million, for the six months ended June 30, compared with a $30.3 million profit last year, after booking a $123.9 million non-cash adjustment related to the windfall levies.
