Petroleum geochemistry of the Otway Basin, and the significance of coastal bitumen strandings on adjacent southern Australian beaches. Volumes 1 to 5 source rock studies.
The standing of crude oil on the beaches of southern Australia was first recorded approximately 150 years ago. This material, known locally as coastal bitumen, was used by the early maritime visitors and settlers to caulk their vessels and is the...-

PEL 32: Pretty Hill Sandstone core-to-log analysis project.
Conventional log analysis of the Pretty Hill Sandstone for Katnook 2 and Ladbroke Grove 1 has not reliably quantified gas-bearing from water-wet zones. This has led to 2 major problems: firstly, log interpretation has been unable to provide...-

New palynology of the Laira Shale in Katnook 1, 2 and 3, Banyula 1, Laira 1, Ladbroke Grove 1 and Kalangadoo 1, Otway Basin, South Australia.
New palynology has confirmed the pattern of algal maxima associated with high gamma ray well log response within the Laira Shale, and indicates that there are 3 major and regionally correlatable 'hot shale' horizons, plus a less obvious one, within...-
