Salamander Energy has failed to hit commercial pay in well Cat Ba-1X (101-CB-1X), in Block 101-100/04 offshore northern Vietnam.
Well 101-CB-1X reached a total depth of 5,656 feet (1,724 meters), encountering 125 feet (38 meters) of net hydrocarbon pay in Tertiary clastics, the second objective of the well. Salamander says the pay section involves a series of gas-bearing sandstones underlain by an oil-bearing reservoir. Wire-line logs and pressure data revealed that the Tertiary reservoirs are of good quality, however, pressure data and seismic mapping indicate the in-place resource volumes encountered are not commercially viable.
Oil shows were not observed and only low levels of gas were recorded while drilling the primary objective, the Palaoezoic ‘buried hills’ play. Therefore, the well was plugged and abandoned as a sub-commercial discovery.
