Offshore Otway Basin core logs (metadata statement and data package)

<div>Gas production from the Inner Otway Basin commenced in the early 2000s but the deep-water part of this basin remains an exploration frontier. Ground-truthing of depositional environments (DE) and gross depositional environments (GDE) is an important contribution to play-based exploration in the Otway Basin. This digital dataset consists of core logs and core photographs of approximately 700 m of core from 19 wells across the entire offshore basin. Observations recorded in the logs include lithology, modal grain size, stacking patterns, carbonate mud percentage, bioturbation index, and DE/GDE intervals. Cubitt et al. 2023 describes how core-based DE/GDE interpretations were applied to wireline log signatures with interpretations made from TD to the base Cenozoic in 38 wells across the basin.&nbsp;DE and DE tracks are included in the well composite logs compiled by Nguyen et al (2024).</div>

Resource lineage

Statement

Well core logs were produced using Mount Sopris’ WellCADTM and wireline logs were analysed with Schlumberger’s TechlogTM software package. The data presented in the well core logs were from Geoscience Australia’s well core analysis and well log analysis. Data extracted from well completion reports (WCRs) include well header information, wireline logging and conventional drilled core descriptions. Well completion reports are available from the National Offshore Petroleum Information Management System (NOPIMS) http://www.nopims.gov.au.
