Use of closure area and resources per unit area for assessing undiscovered petroleum resources in part of the Cooper Basin, South Australia

Abstract

Undiscovered petroleum resources may be assessed using a computer program that simulates drilling each trap in a play end estimates the size of each potential discovery by multiplying together estimates of area of closure (Ad.,) and resources per unit area (V~). There are several ways of determining values for A~ and VA so that the method can be widely applied. As an example, the sales gas potential of pert of the Cooper Basin in South Australia is assessed using statistical projections of Ioglinear models to determine values for A~. and VA.A discontinuity in these particular date appears to result from an improvement in the quality and density of the seismic surveyinsb demonstrating that an assessment based on widely spaced or poor-quality seismic surveys can underestimate sales gas potential.

Acoustic facies on the inner Kara Sea Shelf: Implications for Late Weichselian to Holocene sediment dynamics

“…Studies of raised beaches concentrating on Novaya Zemlya (Forman et al, 1995(Forman et al, , 2004Zeeberg et al, 2001) reported only moderate uplift of maximally 20 m during the Holocene. This implies that isostatic rebound of the Kara Sea coast is less than eustatic rise and the maximum thickness of any ice on the shelf and adjacent coastal plain is unlikely to have exceeded about 500 m (Lambeck, 1995;Lambeck, 1996;Svendsen et al, 2004).…”
