New deeper exploration frontiers in Bass Basin

Abstract

The Bass basin is the sister basin to the Gippsland. Both are extensional
basins in southeast Australia between Tasmania and the mainland, and
both occupy areas in excess of 60,000 km^. The Bass and Gippsland
basins were resurveyed seismically by the Bureau of Mineral Resources to
provide regional correlation and to penetrate seismic energy barriers
caused by Eocene coals.

Analyses of these recent good quality deep seismic data, existing seismic
data, and well information including thermal maturity, source rock
richness, porosity, and permeability suggest that the Bass basin is not fully
analogous to the Gippsland basin. Though stratigraphy is similar, there is
a paucity of significant secondary faulting in Bass basin to act as paths for
migration of hydrocarbons to thermally immature levels, as is the case in
the Gippsland basin. Consequently, in spite of minor oil and gas in the
thermally immature section, the hydrocarbon potential of Bass basin
could be substantially limited to thermally mature levels.
