Abstract
Summary
The effect of pressure was tested on to a joint ultrasonic and resistivity datasets for 67 shaly reservoir sandstones classified into four groups according to clay distribution. We investigated the role of pore-filling and load-bearing clay on the pressure-sensitivity of the relationships between resistivity and velocity (G1), resistivity and attenuation (G2), and velocity and attenuation (G3).The results give useful information for joint property model development for improved hydrocarbon reservoir characterization.
