JAKARTA: Salamander Energy Plc concluded appraisal of the Tutung gas-condensate discovery through the drilling of the Tutung Alpha-3 (TA-3) appraisal well.
The Tutung discovery is located in the Bontang PSC, East Kalimantan, Indonesia. The TA-3 well is currently being suspended, while work continues on the submission of a Plan of Development for the Tutung gas-condensate accumulation, which will incorporate the TA-3 well results, citing the press release in the company’s official site.
The TA-3 well was spudded on 25th March 2012 and drilled to a total depth of 3,351 metres true vertical depth sub-sea (mTVDSS) using the MB Century-28 land rig, on Monday, May 28, 2012.
The well was targeting Middle Miocene sandstones of the Pulubalang formation. The TA-3 well found stacked sequences of deltaic sandstones in the target section on depth prognosis.
These sandstone intervals were evaluated using logging while drilling log data and wire-line pressure testing and gas and fluid sampling. Sandstones within the target formation were found to be gas-bearing, and individual units of up to 15 metres gross thickness were encountered.
The Tutung discovery is located in the Bontang PSC and is approximately 37 km northeast of the producing Sangatta field. Salamander is the operator of the Bontang PSC and has a 100% equity interest.
Salamander has built an extensive exploration portfolio across Indonesia, Thailand, Lao PDR and Vietnam, citing the information from the company’s site.
Production currently comes from three assets, Bualuang Oil Field, Gulf of Thailand, Sinphuhorm Gas Field, Northeast Thailand, Kambuna Gas and Condensate Field, Offshore North Sumatra.
Based on the annual report in 2011, oil production of Salamander dropped 1,700 barrels oil per day (boepd) to 18,600 boepd from 20,300 boepd in the previous year. The company’s oil production from Indonesia was 3,829 boepd last year, coming from SES, ONWJ and Kambuna. (t03/msw)
