Petronas announces gas discoveries in Malaysia, Indonesia and Australia

KUALA LUMPUR, Malaysia -- Petronas has announced 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 250 km northwest of Bintulu, in a water depth of 108 m. It was drilled to a total depth of 2,029 m and encountered 247 m 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 2,521 m and intersected more than 976 m 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.

Petronas holds 42.85 percent equity in the Jabung Block. Overall, Petronas is present in seven blocks in Indonesia, where it operates three of the ventures. SKK Migas, the government authority managing the activities of Production Sharing contractors in Indonesia, has been supportive of the joint venture’s exploration efforts in the block.
Meanwhile in Australia, the Evans Shoal North-1 appraisal well in the Evans Shoal gas field in the Timor Sea has been successfully drilled to the target depth of 3,955 m. The field is located in the NT/P 48 exploration permit in the North Bonaparte basin, which is about 300 km northwest of Darwin. 

A production test of the well, which is located in 111m water depth, flowed gas at a maximum facility constrained rate of 30 million standard cubic ft per day. The partners in the NT/P48 joint venture are Shell (operator; 32.5%), Eni (32.5%), Petronas (25%) and Osaka Gas (10%). The well is operated by Eni on behalf of the joint venture.
