Abstract

Geoscience Australia (GA) has produced a folio of 32 wells across the central and southeast regions of the Otway Basin. This folio covers the areas from Normanby 1 on the Normanby Terrace, through the Shipwreck Trough and Nelson Sub-basin, to Whelk 1 in the southeast. Composite logs for each well in the folio include wireline logs, petrophysical analysis, interpreted lithology, organic geochemical data, organic petrology data, and sequence stratigraphic markers. This folio also includes core-based depositional environment (DE) and gross depositional environment (GDE) interval interpretations which were used to constrain wireline interpretation of DE/GDE away from core control. The folio includes the digital data package used to construct each well composite. The new folio complements a recently published folio of northeast offshore Otway Basin wells, with both designed as resources to support exploration in the offshore Otway Basin.

Keywords: biostratigraphy, depositional environment, gross depositional environment, hydrocarbon prospectivity, lithology, offshore, organic geochemistry, Otway Basin, petrophysical analysis, well data.
