ABSTRACT

Rock physics relationships are an essential element in the evaluation and modeling of seismic attributes for hydrocarbon exploration. Integration of lab- and well-based data is essential in the development of rock physics models with predictive capability. Our integrated workflow for seismic petrophysics includes detailed petrologic characterization, incorporation of fundamental rock properties controls, rigorous petrophysical evaluation, and the use of a core-calibrated rock physics model. Results from a recent integrated study in the Gulf of Mexico yield further validation of the modulus-based model (Kittridge et al., 2004) and provide essential insights into the transition to consolidated sandstone behavior. The new modulus model is different from existing relationships for clean sandstone and we suggest possible causes.
