Gippsland basin

As a first example, we consider the diagenesis of clastic sandstones in the Gippsland basin, southeastern Australia, basing our model on the work of Harrison (1990). The Gippsland basin is the major offshore petroleum province in Australia. Oil production is from the Latrobe group, a fluvial to shallow marine sequence of Late Cretaceous to early Eocence age that partly fills a Mesozoic rift valley.

Amy Berger helped me write Chapter 10 (Surface Complexation), and Chapter 31 (Acid Drainage) is derived in part from her work. Edward Warren and Richard Worden of British Petroleum s Sunbury lab contributed data for calculating scaling in North Sea oil fields, Richard Wendlandt first modeled the effects of alkali floods on clastic reservoirs, and Kenneth Sorbie helped write Chapter 30 (Petroleum Reservoirs). I borrowed from Elisabeth Rowan s study of the genesis of fluorite ores at the Albigeois district, Wendy Harrison s study of the Gippsland basin, and a number of other published studies, as referenced in the text.

We will apply and test this predictive technology in a basin where the sequential carbonate reactions have been well documented (Bodard et al. 1984 Yin and Surdam 1985 Yin 1988) the Gippsland Basin, Australia.

Our interpretation of Fig. 24 is that there should be a significant dolomite dissolution event in the Gippsland Basin at a present-day depth from approximately 1200 to 2800 m. Over this depth interval, the log (AP/K) values are negative and dolomite typically is undersaturated. Points A, B, C, and D correspond to layers presently at 1500, 2800, 3600, and 4800 m depth. The next step in this discussion is to evaluate the quality of the porosity anomaly prediction for the 1200 to 2800 m present-day depth interval.
