SYDNEY, Australia -- Conductor casings for the nine development well slots in the Maari field have now been completed with first oil production expected in February, according to Horizon Oil.
The 24-in. (61-cm) conductor casings were completed to a depth of 260 m (853 ft). The conductors will provide for five oil production wells, three water injection wells, and one spare location.
The jackupEnsco 107 is batch drilling the three production wells with 16-in. (41-cm) casing to a depth of about 900 m (2,953 ft). After that, each well will be drilled to programmed total depth, equipped for production, and turned to the FPSO, which is moored close by.
Earlier, ten 30-in. (76-cm) "stove-pipes" were installed in the seabed below the platform base.
Oil production will ramp up towards the expected initial gross rate of 35,000 bbl of oil as the five horizontal development wells are progressively drilled, the company says.
