Recently formed North Sea heavyweight Harbour Energy expects production to come in at the lower end of its guidance range this year following a period of heavy maintenance as well unplanned stoppages and under-performance at key assets, while full-year capital spending is set to remain unchanged.

The independent, which began trading on 1 April after private equity backed player Chrysaor completed a reverse takeover of UK-listed Premier Oil, earlier set a guidance range for 2021 of between 200,000 and 215,000 barrels of oil equivalent per day on a pro-forma basis and 185,000 to 200,000 boepd on a reported basis.
