Bass Oil plans drilling activity in south Sumatra basin

Bass Oil, Melbourne, has identified expansion opportunities west of Indonesia’s onshore Bunian oil field in south Sumatra basin and plans to start a drilling programme later this year with one firm well and an additional two contingent wells.

As part of its first major new work in the area since the beginning of the COVID-19 pandemic, the company plans to drill the Bunian-6 well in the undrilled southwest part of the field and a third well to appraise the Bunian 3P extension area.

The company expects to hold production steady through 2021 with drilling aimed at boosting production in 2022.

The expansion drilling programme is aimed at building daily output from about 500 b/d from four production wells within the Tangai Sukananti KSO licence which hosts Bunian and Tangai oil fields and follows a comprehensive integrated reservoir study over the past year updating static and dynamic reservoir models following drilling of the Bunian-5 development well.

The study identified a number of production and reserve growth opportunities, including drilling the Tangai-5 development well updip of existing producers, identifying major extension of Bunian field to the west, possible extension of Bunian field with appraisal and development drilling, and modelling K reservoir in Bunian to improve recoveries and reduce development costs through application of horizontal drilling techniques.

Bass is operator in the license with 55% working interest.
