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...

Highlights of the above 4 parts of the report include: 1) A brief review of the Palaeozoic, Mesozoic and Cainozoic tectonic history. 2) The limited amount of useable seismic, aeromagnetic and gravity data hampers structural definition of the basin....

The aim was to derive a new method for the evaluation of porosity and water saturation for Pretty Hill Sandstone reservoirs, Otway Basin. Over 350 core plugs were measured for ambient and overburden porosity and permeability, and absolute grain...

A promotional brochure for vacant offshore Otway Basin petroleum exploration acreage, designed for release overseas to potential corporate bidders, prior to gazettal of the area for permit applications in November 1992. Area S92-1 covering 4736 square...

Two samples from Killarney 1 were analysed to determine whether basement (meta-sediments and/or meta-volcanics) are present in the lower part of the well. The samples contain palynofloras correlative with the F. wonthaggiensis Zone (the upper part)....

Contains a report describing how MESA estimated the initial pressure and gas-in-place of the Pretty Hill Sandstone reservoir in the Katnook Field.

In order to examine the prospectivity of EPP 23, for which they assumed the operatorship by a 65% farm-in in August 1990, BHP Petroleum have examined well palynological and geochemical data in and around the permit and have interpreted over 600 km of...

This compilation of available geological and geophysical data pertaining to PEL 27, and open file plus traded data from adjoining tenements, assembled in June 1992, was instigated by the PEL 27 joint venture to provide a comprehensive basis on which...

Comprises details of the operations, field acquisition, results and interpretation of the seismic survey. The survey aimed primarily to map five basement features (Beachport, Lake Eliza, Lucindale, Camelback and Mount Hope). Results indicated these to...

EPP 24 lies in the north-western corner of the Otway Basin, offshore from Robe, South Australia. The permit geology is dominated by sediments of the Early Cretaceous Otway Group. A tectonic hinge-line called the Chama Terrace runs obliquely from...

During its permit tenure the BHP/Esso joint venture carried out 6 seismic surveys and drilled 4 exploratory wells in attempting to ascertain whether commercial hydrocarbon deposits existed within the area. Although the geological prognoses...

There is no abstract created for this record

Comprises details of the operations, field acquisition, results and interpretation of the seismic survey. A total of 158 km were recorded comprising 70 km 6-fol CDP, 71 km 12-fold and 17 km of tapered coverage below 6 or 12-fold; an additional 8 km of...

Thirty samples from the Tertiary, Cretaceous and pre-Cretaceous were examined for organic matter type and abundance and maturation level. The source potential of the Lower Cretaceous is fair to good, but the deepest part of the Eumeralla Formation...

Technical data related to the Banyula 1 well proposal, dealing with environmental protection, geological, drilling engineering and associated work practice methods.

Exploration activity in the permit has included: - the SA 18-81 Marine Seismic Survey (see Env 4286); - the SH 18-81 CH geochemical sniffer survey (see Env 4506, vol 1); - a seabottom site investigation prior to drilling Breaksea Reef 1 (see Env...

AIM: To locate and provide modern seismic control over areas, prospective on the basis of gravity and existing seismic data, where the Pretty Hill Sandstone could be in a favourable structural position, and to provide additional regional control....

This study concentrates on the correlation of lithostratigraphic units, establishing a model for the likely source rock maturity pattern, and elucidating the structure, seal and reservoir relationships. The Early Cretaceous Otway Group is considered...

Contains a report on seismic modelling of the Pretty Hill Sandstone section in the well,and a regional petrological review of this formation centering on Sawpit 1 data, plus some brief faxed comments regarding the well palynology.

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...
