Serica Energy said production is now back on track after the Erskine field was interrupted by a blockage earlier this year.
The company said it had strong production in January and February averaging over 3,200 barrels of oil equivalent per day.
After production was interrupted by a blockage in downstream condensate it came back online and is now performing at more than 2,700 barrels of oil equivalent per day.
Work is also continuing on optimising the Columbus development plan in conjunction with other asset owners in the area.
Serica said the net loss for the first half of the year was $2.8million as a result of the field shut-in.
Cash at the end of this month was $13.1million after second stage payment to BP and ongoing Erskine costs.
