Dual Porosity Biot-Barenblatt Model

Dual porosity Biot-Barenblatt poroelastic model is analyzed. P-wave reflection at an impermeable interface between elastic and dual-porosity media is investigated. Asymptotic low-frequency analysis of the planar p-wave reflection coefficient from a hydrocarbon reservoir shows that the frequency-dependent component is proportional to the square root of the reservoir fluid mobility. Frequency-dependent seismic attribute analysis has been applied for mapping of high fluid mobility zones of oil-saturated reservoirs. As the obtained asymptotic scaling links reservoir rock and fluid properties with seismic attributes, it has a great potential for hydrocarbon exploration and production.
