This represents the thickest penetration to date in the Bualuang field and a preliminary net pay count in this interval is c. 25 meters.
Operations
Three additional sandstones were encountered above the T4 reservoir and were found to be oil-bearing, with some seven meters of net pay over this interval. At the deeper objective below the T4 reservoir, eight meters of net oil pay was intersected in the T2 oligocene syn-rift section. Crude oil samples have been taken from this interval and analysis shows this to be 33 degree API oil, while the main T4 reservoir on the Bualuang field is 27 degree API.
On completion of wireline logging and fluid sampling the BA-11P well was plugged and steered into the top of the T4 reservoir as well BA-11H, the first horizontal producer on the Bualuang field.
The BA-11H well, along with the other horizontal producer, BA-12H, were completed in a crestal area of the field and consist of 250 meter horizontal sections in a target zone 2-3 meters below top reservoir. Both wells have now been brought on-stream and tested at over 18,000 barrels of oil per day (bopd). The two wells are now being choked back to produce at a rate of c. 14,000 bopd as we manage the reservoir to optimize reserves recovery.
The Kambuna field development, offshore North Sumatra, Indonesia continues to progress. The gas sales agreement with Pertiwi was signed in May 2009 and the remaining gas sales agreement with PLN is expected to be signed in the coming weeks. The multi-phase pipeline from the field to the processing facilities onshore at Pangkalan Branden has been completed. The early production system continues to be fitted out and assembled in Batam ahead of transportation to the Pangkalan Branden site. Production is expected to start up around the mid-year.
Portfolio Development
In March 2009 Salamander Energy announced that it had signed production sharing contract (PSC) for block 31, offshore southern Vietnam. Salamander Energy is the operator of the PSC with a 60% working interest.
Block 31 covers an area of over 5,000 square kilometers and is adjacent to and outboard of Salamander Energy’s operated block Cuu Long River Delta 01 (DBSCL-01) PSC. Recently acquired 2D seismic data across the acreage indicates the presence of a high quality oil-prone lacustrine source rock and multiple play types. The company is continuing to process this data with a view to drilling in first quarter 2010.
