Australian independent Carnarvon Petroleum has been awarded two nearshore shallow-water exploration blocks in Western Australia that contain an existing oil discovery.

The Perth-based company said Blocks EP509 and TP29 are adjacent to each other and lie south-west of Barrow Island in less than 50 metres of water depth, "and within a prolific region of the Barrow sub-basin".

The Pepper-1 discovery well, drilled by Wapet in 1970, sits within the awarded blocks.

Carnarvon’s modern integrated petrophysical analysis of Pepper-1 estimates a live hydrocarbon column within the Jurassic Dupuy reservoir.
