PhD Project:

Sedimentology and Sequence Stratigraphy of the Early Triassic Rewan Group, Bowen Basin

Commenced: 1994

Supervisor: Dr Nick Lemon, Dr Neville Alley (PIRSA)

Project support: Industry

Scholarship support: The University of Adelaide

Outcrop, wireline log, biostratigraphy, core and seismic data were integrated in this study of the Rewan Group in the Bowen Basin to achieve an understanding of the depositional systems involved. The major objective is to clarify the sedimentology and stratigraphy of the Early Triassic sand bodies and identify potential reservoirs.

Detailed outcrop stratigraphic work and core logging was carried out in Queensland. Seismic data had been interpreted and at an earlier stage of the project, in an effort to use seismic sequence stratigraphy to interpret depositional facies. This direction was abandoned because quality of the data did not allow such an approach. However, some aspects from this earlier work will be integrated into the overall sequence stratigraphic interpretation, resulting in an improved depositional model for the Rewan Group.

A major aspect from this study has been the understanding of continental sequence stratigraphy. A new model has been proposed and was presented in June 2000 at the Sprigg Symposium in Adelaide, and in July 2000 at the AAPG Regional Conference in Istanbul.
