AIM: The 1992 Western Atlas Seismic Survey programme was aimed primarily at confirming the closure of the Investigator strong lead, a large, complex Lower Cambrian carbonate play situated at the southern end of the Marsden Trend, and secondly was...

Port Julia 1A was recently drilled by BHP Minerals in EL 1112 to investigate a bullseye magnetic anomaly, but failed to realise its mineral-related objective. The well was fully cored through the Cambrian Coobowie Limestone, Moonan Formation and...

The Stansbury Basin is a relatively unexplored Cambrian sedimentary basin in South Australia. Good quality seismic data has defined a large untested prospect, the Investigator prospect, which has the potential to contain 200 to 300 mmbbl of oil, or...

The Heatherdale Shale and the stratigraphically younger Karinya Shale are transgressive units within the Lower Cambrian of the Karinya Syncline. Black muds of the Heatherdale Shale were deposited in an outer ramp setting of the Stansbury Basin under...

A Houston, Texas, consultant's offshore operational weather risk background data provided to the PEL 53 licensees on: Estimates of extreme wind and wave conditions for four locations in Investigator Strait for 10 and 50 year return periods; Wind and...

Field examination of common asphaltite occurrences on Kangaroo Island beaches has concluded that they are relatively recent strandings of unknown origin and age. Their presumed sea floor mode of transport indicates a likely nearby source within the...

This study has shown that significant dolomite formation has occurred during early diagenetic stages in the Early Cambrian carbonate sequence of Yorke Peninsula. Relict depositional textures indicate that the sequence consists of tidal flat...

This report critically reassesses the biomarker geochemistry of the crude oil show encountered in the Wilkatana 1 well, using new analytical data, then compares its molecular composition with that of other Australian Cambrian oils, and discusses the...

19 selected drillcore plug samples taken from Cambrian dolomitic limestone and sandstone potential reservoir beds in 4 Stansbury Basin wells, were analysed for their permeability to air and helium injection porosity, at ambient conditions. However,...

17 samples of Early Cambrian Mount McDonnell Formation shallow marine mudstone outcropping on the northern coastline of Kangaroo Island near Hummocky Point were analysed geochemically to determine their source rock richness and thermal maturity, and...

AIM: The 1993 Troubridge Shoals Seismic Survey programme, of shallow water/shelf transition zone coverage on the southwestern and western sides of Gulf St Vincent, was designed to tie the extensive offshore seismic data of recent vintage to the...

Geothermal modelling has been carried out at 9 locations in or around the Stansbury Basin, at the request of Canyon Australia, with the aim of examining the basin's thermal history and deducing a likely time of petroleum generation. A total of 20...

Special seismic processing of three offshore seismic lines in south-western Gulf St Vincent was undertaken for Canyon by a Houston, Texas - based consultant, who performed a high resolution velocity analysis using the pre-stack migrated data, followed...

Report summarises the stratigraphic, sedimentological and organic geochemical data so far assembled for the Heatherdale Shale where it outcrops on the Gulf St Vincent coastline south of Adelaide, with the aim of: - establishing the location and...

A detailed study of the stratigraphy, sedimentology and thermal history of the Heatherdale Shale, the youngest unit of the Early-Mid Cambrian Normanville Group (Fleurieu Peninsula, South Australia), was undertaken to elucidate its petroleum source...

Interpretation of airborne geophysical data covering the Gulf St Vincent region has utilised predominantly 1964 vintage gravity and aeromagnetics that have been digitised off original Beach Petroleum contour maps, plus limited well log and seismic...

AIM: To acquire regional seismic information about deep basinal structuring and pre-Mesozoic sedimentary history beneath the central portions of the SA gulf waters and their linking shelfal strait, in order to help promote the region's untested...
