During pump tests of water wells in completed within fractured rock aquifers, the amount of drawdown to the standing water level frequently increases linearly with the square root of pumping time. Long-term, however, the drawdown will depend on the...

Late in 1976, the Mintaro Slate and Flagstone Company approached the South Australian Department of Mines seeking assistance to enable it to improve the efficiency of its operation and so enable it to operate more profitably in the face of competition...

Geophysical and geological surveys and drilling in the Northern Adelaide Plains of South Australia have located a Tertiary palaeochannel incised within Proterozoic bedrock. Present data indicate favourable reservoir and seal conditions for the...

This Department received a request from the E. & W.S. to drill a replacement hole for their No. 1 well at Melrose, known as Dickson's Bore which-had partially failed. Failure was caused by sand entry into the hole and subsequent pump damage. Poor...

New production water well was drilled to 71 metres.

The purpose of petroleum well log evaluation is quantitative determination of the possible presence of hydrocarbons. This necessitates making calculations of porosity and water saturation for many intervals within the well, using various log...

Exploration for a suitable underground gas storage target in the Northern Adelaide Plains was initiated in 1964. Prior to the present investigation, four other areas have been examined and rejected as target areas, mainly due to the shallow depth of...

Two production water wells were drilled during March-May, 1974. The wells are located about 1 km apart within the Coober Pedy town area, and both draw upon the Cadna-Owie Formation. Salinity is uniformly high in both holes, at 16,600 - 16,700 mg/l....

An assessment has been made of South Australia’s energy resources. Hypothetical and uneconomic resources have been assessed as well as those which are identified and economically recoverable. The conclusions which emerge are (1) there is a complete...

A geological mapping and drilling programme has shown that the making of a tunnel through Wylie Ridge is geologically feasible. The route will pass through folded quartzite and siltstone, and the rock mass possesses various discontinuities which will...

Due to substantial funding by NERDDC of this project, over 850 new core plugs from 46 wells in the Cooper Basin in South Australia were analysed to provide a database for improvement of porosity and water saturation log analysis algorithms currently...

The Departments method for estimating and reporting gas reserves has been revised to include estimates of tight gas as well as providing more accurate estimates of conventionally recoverable gas reserves. This has included a new method for...

For the past 30 years or more, much of the town water supply for Orroroo has come from wells that are completed in the confined aquifer of the Walloway Basin. The unconsolidated, fine, silty sands of this aquifer become mobile and have led to a...

Aquifer storage and recovery (ASR) is being developed as a solution to provide an emergency town water supply in a location where blue- green algae make River Murray water unfit for domestic use during summer. Algae-free river water will be injected...

A public review of the Cooper Basin (Ratification) Act, 1975 and Indenture (the Ratification Act) has been initiated by the South Australian Government. The review fulfils obligations under the February 1994 CoAG Agreement for Free and Fair Trade in...

The Petroleum Division of Mines and Energy South Australia (MESA) engaged GPA Engineering to provide cost estimates to feasibility study level for processing and transporting products from new gas discoveries in the Cooper Basin, both on a stand-alone...

Aquifer storage and recovery investigations at well 6628-16623 drilled by MESA in The Paddocks wetland storm water treatment and holding site in the Salisbury Council area (Adelaide, South Australia) have been successfully completed. The work...

Recently imposed water resource management controls in the Angas - Bremer Irrigation Area have reduced the local irrigators' aggregate groundwater allocation to within the sustainable limits of the basin, primarily by conversion of their licences...

An aquifer storage and recovery scheme is being developed at Clayton township on Lake Alexandrina, South Australia, notably as a solution to provide a town water supply in a location where blue-green algae make River Murray water (extracted via the...
