Integrated Characterization Workflow to Assess Diagenesis Impact on the Petrophysical and Petroacoustic Properties of Carbonate Reservoirs

摘要

The characterization, modeling and production of many carbonate reservoirs pose significant challenges due to multiscale geological heterogeneities resulting from the combination of sedimentary and diagenetic processes. This paper proposes an integrated geological, petrophysical and petroacoustic workflow designed to derive correlations between the petrophysical and petroacoustic signature of key reservoir facies and their microstructure. The ultimate objective of this workflow is to provide a reservoir model populated with petrophysical and petroacoustic properties consistent with geological description. First results obtained on a well-preserved Oligo-Miocene succession of mixed carbonate-siliciclastic facies outcropping in the South-East of France have been used as a guiding line to discuss the successive workflow steps and their interrelations.
