Brief description

Geoscience Australia (GA) has produced a folio of 32 wells across the central and southeast regions. 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, and both were designed as resource for exploration in the offshore Otway Basin.

Statement:

Well composites were produced using Schlumberger’s Techlog software package. The information used for the well folio were primarily extracted from well completion reports (WCRs) and destructive analysis reports (DARs), and the digital data are maintained in Geoscience Australia’s databases. These data include well header information, formation evaluation logging, cuttings, sidewall core and drill core lithology, organic geochemical data, oil and gas shows, and stratigraphy. To ensure uniformity across wells, geological names from Geoscience Australia’s Australian Stratigraphic Unit Database (https://www.ga.gov.au/data-pubs/datastandards/stratigraphic-units) were used and geological names from the original data sources were replaced where necessary. Well lithologies were interpreted and petrophysical analyses undertaken to characterise potential reservoir and source rock units. Organic geochemical, including total organic carbon (TOC) content from LECO and pyrolysis data, as well as organic petrological data were compiled to evaluate source rock quality and thermal maturity. Further details are provided in the metadata statement.
