Abstract

The Bass Basin is a moderately explored Cretaceous to Cainozoic intracratonic rift basin on Australia's southeastern margin, underlying the shallow seabed between Tasmania and the Victorian mainland (Bass Strait; Figure 1). The basin contains proven commercial reserves of gas and condensate that are soon to be developed (Yolla gas field, Origin Energy Resources Ltd-operated BassGas Project). Other discoveries in the basin include the White Ibis and Pelican gas fields. To date, the 32 wells drilled have targeted Upper Cretaceous to Middle Eocene reservoirs within fault blocks and anticlinal structures. The targeted succession comprises interbedded fluvio-deltaic and lacustrine sandstones, siltstones and shales. The principal source rocks in the Bass Basin are interbedded coals (ranging from 5 to 25 m thick) and lacustrine shales of early Palaeogene age. Geochemical analyses show these source rocks have generated liquid and gaseous hydrocarbons, with the coals being the dominant source for the liquids (Boreham et al., 2003).
