The effect of chemical and physical processes on the acoustic properties of carbonate rocks

Stanford University, Stanford, USA

Corresponding author: tvanorio{at}stanford.edu

Carbonate rocks have major economic significance; 60% of the world's oil reserves lie in carbonate reservoirs and the potential for additional gas reserves is huge. However, the relationship in carbonates between measured geophysical data and rock properties is complex, due to the large variety of textures that arise during postdepositional diagenesis and to the chemical processes (i.e., dissolution and replacement by newly formed phases) that characterize carbonate-forming minerals. Most experimental and theoretical rock physics research has focused on siliciclastic and shaly rocks. However, applying insights gained from clastics to carbonates is rarely straightforward, and thus is questioned in the literature.
