The well, which was drilled to a total depth of 1,724m, encountered 38m of net hydrocarbon pay in Tertiary clastics, the secondary objective of the well.

According to the company, the pay section comprises a series of gas-bearing sandstones underlain by an oil-bearing reservoir.

The Tertiary reservoirs are of good quality, however pressure data and seismic mapping shows the in-place resource volumes encountered by the well are probably below levels needed for commercial development.

Salamander said that no oil shows were observed and only low levels of gas were recorded while drilling the primary objective, the Palaeozoic ‘buried hills’ play.

The company has subsequently plugged and abandoned the Cat Ba-1X well as a sub-commercial discovery.
