The Perth-based mid-cap holds a 12% stake in the Enoch field, which is 250km northeast of Aberdeen, straddling the UK and Norwegian international boundary.

Once its Blane oil field comes onstream later this year, about 25% of Roc’s production will come from the North Sea, according to managing director John Doran.

“Enoch represents another production box ticked, this time in the North Sea,” he said.

“As a result, Roc’s company-wide production has kicked back into the 10,000-12,000bopd range.”

Enoch production is transported to and processed at the nearby Brae Alpha facility, about 15km northwest.

In warmer waters, the company says production from its troubled Chinguetti oil project fell further last month to just 17,600bopd from six wells including the recently completed infill development well.

Meanwhile in China, the company says its Zhao Dong C&D oil fields averaged 20,000bopd in May.

Development drilling that started in May will result in additional nine producers and six water injectors being drilled. This is expected to lift field-wide production to 25,000bopd.

In Angola, drilling of the company’s Massambala-1 well has been delayed due to heavy unseasonal rain over the last weeks.

The Roc Explorer rig is expected to spud the well within the next two weeks.

Refurbishment of the Simmons 80 rig in Dubai is almost complete and the unit is expected to be ready to start in Angola in July.
