Petroleum System of Evans Shoal Gas Field, northern Bonaparte Basin, Australia

Evans Shoal Gas Field comprises the wells Evans Shoal-1and Evans Shoal-2 .Our study aimed to determine the hydrocarbon potential of the main source rock in the study area and analyze the petroleum systems and guide future hydrocarbon exploration and development. The methods used encompass BasinMod techniques using mathematical methods. Analysis of the source rock potential helped to identify th...

Feasibility of time-lapse gravity monitoring of producing gas fields in the Northern Carnarvon Basin, Australia

Figure 1. Model of P-wave velocity (above) and density (below) verses gas saturation for a sandstone reservoir with a porosity of 25%. The velocity was modelled using Gassmann’s equation (1951) with the Reuss average moduli of the fluids. For a gas saturated reservoir, a decrease in gas saturation causes a negligible change in the P-wave velocity for saturations above 20% and more significant c...

Estimating pore pressure in the Cooper Basin, South Australia: sonic log method in an uplifted basin

The use of sonic log data to analyse overpressure in the Cooper Basin, South Australia is complicated by the occurrence of Tertiary uplift in the basin. Uplift and overpressure are both associated with anomalous porosity/depth relationships: the former being witnessed by overcompaction and the later by undercompaction. Hence uplift may mask overpressure effects on log data. A normal compaction ...
