Salamander Energy plc reported that the G4/50-4 exploration well, targeting the Rayong prospect in the Kra Central sub-basin, Block G4/50, Gulf of Thailand, has been drilled to a total vertical depth subsea of 6,198 feet (1,889 meters).
The well encountered a 390 feet (119 meter) section of excellent quality P20 Miocene sandstones, the primary target on depth prognosis. However, following the completion of a logging and sampling program, these sandstones were found to be water-wet.
In the deeper Permian carbonate target the well encountered a 112 feet (34 meter) section of Ratburi limestone which was not deemed to be of reservoir quality.
The well has been plugged and abandoned and the Atwood Mako (400' ILC) is now mobilizing to drill the Surin prospect in the Western Central sub-basin.
