The DBSCL01-TSL-1X well, the first exploration well in the basin, has been drilled to a total vertical depth sub-sea of 1,380mt. Following the completion of wire-line logging operations, the well has been plugged and abandoned as a dry hole. The well encountered both potential seals and high quality reservoir sandstones, which were water-wet in the Tertiary clastic section.
The PVD-1 jack up rig will now move approximately 25km south to drill the 31-Tom Hum Xanh-1X (THX-1X) exploration well in Block 31. This well is targeting an oil prospect with a mean gross pre-drill recoverable resource estimate of approximately 80mmbo.
James Menzies, chief executive of Salamander, said: “As the first exploration well in an undrilled basin, the Tom Su Lua prospect was viewed as high risk. Although a dry hole, the TSL-1X well confirmed certain elements of the play system in the Vin Chau graben.
“We now look forward to drilling the THX-1X exploration well, while we continue to analyze the valuable geological information provided by the TSL-1X well.”
