Emperor Energy Ltd., Sydney, said new amplitude versus offset (AVO) analysis of Kipper and Golden Beach sands overlying its Judith gas field in permit Vic/P47 in Bass Strait indicates the potential for additional gas play across the permit and the field.
Analysis was carried out with new fully processed 3D seismic data run on the two potential reservoir sands that lie above the Judith gas sands that currently comprise Judith field prospective resources.
Results indicated strong AVO response in the Kipper sand as well as three zones within the Golden Beach sands.
The results correlate against reservoir gas in the nearby ExxonMobil-operated Kipper-1 well where the Kipper and Golden Beach sands are the principal reservoirs in Kipper field.
Initial calculations of rock volumes indicate the four intervals have the potential to contain significant gas in place to add to the existing P50 unrisked prospective gas resource of 1.226 tcf within the permit area, Emperor said.
The company is now working on new gas in place calculations prior to upgrading prospective resources.
Emperor’s focus is the development of Judith field 40 km offshore from the Orbost gas plant in eastern Victoria. The objective is to establish a sales gas capacity of 80 terajoules/day (28 petajoules/year) over a minimum of 15 years.
