Abstract

Vast areas of Australia’s sedimentary basins have not been properly explored for oil and gas. The areas are generally remote from-population centres so that exploration, particularly seismic, is expensive. In these circumstnaces gravity exploration if properly applied has a great deal to offer. It is therefore appropriate to attempt to disseminate an understanding of gravity interpretation to encourage its proper application.

The basic theme of this workshop manual is the nature of gravity anomalies amenable to interpretation and their causative geology in a sedimentary basin environment. An interpretation procedure that is known to work well and an example of its application in the Perth basin are described to complete this work.
