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...-

RB 81/00093 South-East water resources. Coonawarra groundwater investigation, progress report no. 1.
Coonawarra is important viticultural area. Its establishment was possible because of low salinity groundwater and suitable soil. Since 1970 groundwater levels have shown no significant decline due to irrigation and no increase in salinity. A pollution...-

RB 93/00051 Otway Basin hydrogeological investigation. Phase 2 - Groundwater residence times.
Stable isotopes (deuterium, carbon-13 and oxygen-18) and radiocarbon (carbon-14) have been used in conjunction with chemical data to evaluate recharge mechanisms, groundwater residence time and palaeohydrology within the confined Dilwyn Formation sand...-

RB 95/00017 Gas sampling from water bores in the northern Gambier Basin, South Australia.
In January 1993, 15 water bores in the South-East were sampled for headspace gas. 7 of these bores provided sufficient gas for compositional analysis of hydrocarbons. Methane values ranged from 25% to 92% of the total gas for these bores, with...-

Preliminary evaluation of the source rock potential of the Eumeralla Formation in Chama 1A and Geltwood Beach 1, Otway Basin.
Organic petrology, total organic carbon (TOC), Rock-Eval pyrolysis and preliminary biological marker data are summarised to provide an assessment of the source rock potential of the Eumeralla Formation in the subject wells. The findings are as...-

Preliminary report on the biomarker geochemistry of rock extracts from Chama 1A and Geltwood Beach 1: comparison with some Otway oils and coastal bitumens.
Organic geochemical analyses were carried out on 6 rock sample pyrolysis extracts from Chama 1A and 7 from Geltwood Beach 1 to determine whether the Crayfish and/or Eumeralla formations in these wells could be a source for the asphaltites and bitumens...-

RB 00728 Gravity interpretation of the western Otway Basin between Cape Jaffa, SA, and Warrnambool, Victoria.
From Bouguer anomaly maps of the western onshore portion of the Otway Basin, a residual gravity map has been constructed, from which the subsurface geological structure is interpreted to give good agreement with known geology. The area is one of...-

Vertical groundwater recharge to the Tertiary confined sand aquifer, South-East, South Australia.
Groundwater flows mainly through two major aquifer systems: a regionally unconfined aquifer, and an underlying confined aquifer. The two aquifers are separated by a low permeability confining bed (or aquitard). Determining the degree of hydraulic...-
