Malaysia's state-owned Petroliam Nasional Berhad (Petronas) announced Thursday new gas discoveries in three of its upstream ventures in Malaysia, Indonesia and Australia.
The first discovery is via the Pegaga-1 well in Block SK320, offshore Sarawak, which is operated by Mubadala Petroleum through a Malaysian affiliate. Petronas Carigali Sdn Bhd, a subsidiary of Petronas, has a 25 percent interest in the block.
The Pegaga-1 well is located about 155 miles (250 kilometers) northwest of Bintulu, in a water depth of 354 feet (108 meters). It was drilled to a total depth of 6,657 feet (2,029 meters) and encountered 810 feet (247 meters) of gas column.
The well flowed gas to the surface and pressure data indicates the possibility of a substantial gas column still not penetrated by the well. The operator plans to conduct further drilling to determine the volumes of the discovery and the gas quality.
Pegaga-1 is the second successful gas well for the joint venture partners in Block SK320 after the M5-2 well drilled in 2012.
In Indonesia PetroChina, which is the operator of and Petronas’ partner in the onshore Jabung Block in Sumatra, has made a gas discovery through the NEB Base-1 well. This discovery is significant as it confirms the presence of hydrocarbons in a new exploration play consisting of fractured granite in the block.
PetroChina has drilled the NEB Base-1 well to a depth of 8,271 feet (2,521 meters) and intersected more than 3,202 feet (976 meters) of granitic basement of Pre-Tertiary age. The well has been temporarily suspended and planning for testing operations is in progress, including acidisation of the fractures to enhance hydrocarbon flow rates.
