- Combined analysis of different logs in quantification of exhumation and its implications for hydrocarbon exploration, a case study from Australia A. Mavromatidis Ciencias de la Tierra Compaction Density log Neutron log Eromanga basin Adjusted sonic log Exhumation in the Eromanga Basin of South Australia and Queensland has been quantified using the compactionmethodology. The standard method of estimating exhumation using the sonic log has been modified andthe adjusted sonic, the bulk density and neutron logs, have been used to estimate exhumation. Additionally theuse of a single shale has not been adopted, and seven units, ranging in age from Cretaceous to Jurassic havebeen analysed. All units yield similar results; and burial at depth greater than currently observed is the mostlikely cause of overcompaction. The use of the adjusted sonic, bulk and neutron logs have been justified. Thisstudy has major implications for hydrocarbon exploration since predicted maturation of source rocks will begreater for any given geothermal history if exhumation is incorporated in maturation modelling. 2006 artículo científico 1695-6133 https://www.redalyc.org/articulo.oa?id=50540302 en http://www.redalyc.org/revista.oa?id=505 Geologica Acta: an international earth science journal application/pdf Universitat de Barcelona Geologica Acta: an international earth science journal (España) Num.3 Vol.4
