Salamander has completed the Angklug-1 well as an oil and gas discovery. Drilled by the HAKURYU-5 semisub, the well reached a true vertical depth of about 9,350 feet (2,850 meters), encountering 75 to 89 feet (23 to 27 meters) of net gas pay in a high-quality Lower Pliocene sandstone unit at a depth of 6,070 feet (1,850 meters).
Log evaluations have indicated that the formation has porosity of up to 30% and permeability of around 50 millidarcies. A drill stem test was performed, which flowed at a constrained rate of about 24 MMcf/d without any indication of CO2 or H2S. Strong gas shows were also uncovered in the deeper section of the well. The well encountered a gross 840 feet (256 meter) section of inter-bedded sandstones and shales of Upper Miocene age, thought to contain a net 394 feet (120 meters) of oil-bearing sandstones. However, sampling and pressure testing revealed the sandstones were too tight, having low permeability, and are not considered net pay.
The operator will now conduct additional technical work to evaluate both the resource potential of the discovery, and the large inventory of prospects within Salamander's acreage. The Bontang PSC is located in the Kutei basin, East Kalimantan, Indonesia, and is operated by Salamander Energy.
