The five-month facilities upgrade program involved more than 100,000 man-hours of work offshore by local contractor Unithai, with the accommodation bargePosh Bawean hosting more than 200 personnel.
Ophir adds that the sub-surface part of the project concluded at the end of last year with drilling of a new water disposal well and the workover of the existing water disposal wells.
The project has increased the design capacity of the water handling and disposal system from 50,000 b/d to 75,000 b/d.
Currently production is ramping up as the new system is brought onstream and tested. On Sunday theBualuang field was producing 9,700 b/d of oil at a water disposal rate of 64,000 b/d, an increase of 1,400 b/d of oil compared to production in late August prior to commissioning of the new facilities.
Capex for the campaign was $20 million.
