New gas discoveries made in S’wak, Indonesia and Australia


KUCHING: New gas discoveries have been uncovered in three of Petronas’ upstream ventures in Sarawak, South Sumatra in Indonesia and Australia.

The Pegaga-1 well in Block SK320, offshore Sarawak, which has been drilled to a total depth of 2,029 metres and encountered 247 metres 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 and further drilling will be conducted to determine the volumes of discovery and gas quality.

This discovery proves that there is still hydrocarbon potential in the Sarawak Basin.

Petronas, together with its Production Sharing Contractors, is actively exploring the basin through exploration drillings in both shallow and deep water areas.

They are also acquiring new seismic, electromagnetic and gravity data to unlock the undiscovered potential of the areas.

Several oil and gas multinationals have been successful in their recent exploration drilling in Sarawak with several notable discoveries such as NC3/NC8, B14, Tukau Timur Deep, Kuang North and Kasawari.

These exploration efforts have opened up several new hydrocarbon play-types in the basin.

Meanwhile in Indonesia, PetroChina which is the operator and Petronas’ partner in the onshore Jabung Block in Sumatra has made a gas discovery through the NEB Base-1 well.

The discovery is significant as it confirms the presence of hydrocarbons in anew exploration play consisting of fractured granite in the block.

The NEB Base-1 has been drilled to a depth of 2, 521 metres and has intersected more than 976 metres of granitic basement of Pre-Tertiary age.

The well has been temporarily suspended and planning for testing operations are in progress, including acidisation of the fractures to enhance hydrocarbon flow rates.

In Australia, the Evans Shoal North-1 appraisal well in the Evan Shoal gas field in the Timor Sea has been successfully drilled to the target depth of 3, 955 metres.

A production test of the well, which is located in 111 metres water depth, flowed gas at a maximum facility constrained rate of 30 million standard cubic feet per day.
