✦ Synopsis

Experimental data on acoustic wave propagation through oil shale, summarized in a previous paper', were used to develop a semi-empirical model. This model predicts the variation of pressure, effective compressional wave velocity, effective density and acoustic impedance with depth for a modified insitu oil shale retort. Results from computer simulation of a variety of retort conditions establish the possibility of employing seismic propagation and reflection techniques for mapping of pyrolysis fronts in in-situ oil shale process beds. Such techniques are potentially free from uncertainities associated with proximate sensing of temperature profiles in these beds.
