The survey is expected to further define the reservoirs in five producing oil fields, including the Talgeberry, Mulberry, Gimboola, Cranstoun and Endeavour.

It will address additional 1P and 2P reserves and 4.7 million bbls of 3P undeveloped reserves within these producing fields, which cover potential oil zones in the Birkhead, Wyandra, Murta and Westbourne Formations.

The survey will also provide data to identify and map at least 10 remaining undrilled structures and address a possible 4.37 million bbls of oil.

Santos is the operator. Drillsearch Energy holds a 10% working interest in the Tintaburra Block.
