Abstract
The Tuna Field in the Gippsland Basin southeastern Australia hosts Late Cretaceous fluvial siliciclastic oil and gas reservoirs that have proved difficult to correlate seismically. Previous correlations of the reservoir facies have been achieved using a combination of well data (wireline log, cuttings and core) and qualitative palynological data. This study integrates new detailed facies and palynological analyses that improve reservoir correlation across the Tuna Field. Specifically, investigation of the Campanian sections in Tuna-1 and Tuna-4 wells has resulted in a revision of the age assigned to the strata. In addition, the facies analyses of these two wells, supported by wireline log in..
