Premier said in a trading update this week that overall production for the year to date has averaged 57,100 barrels of oil equivalent per day, with summer maintenance work already complete and output back to previous levels.

As a result, production remains ahead of full-year guidance of 55,000 boepd before any contribution from Solan, the company said.

Premier said it anticipates first oil from Solan in the final three months of 2015, in line with previous guidance.
