Analysis and evaluation of interwell seismic logging techniques for reservoir characterization. [Quarterly report], January 1--March 31, 1993

The objective of this three-year research program is to investigate interwell seismic logging techniques for indirectly interpreting oil and gas reservoir geology and pore fluid permeability. This work involves a balanced study of advanced theoretical and numerical modeling of seismic waves transmitted between pairs of reservoir wells combined with experimental data acquisition and processing of measurements at controlled sites as well as in full-scale reservoirs. This reservoir probing concept is aimed at demonstrating unprecedented high-resolution measurements and detailed interpretation of heterogeneous hydrocarbon-bearing formations. Technical progress for the past quarter is summarized for Task 3, data processing and analysis of geological and petrophysical analysis of the interval from 800 to 1100 feet in five wells at the Gypsy Test Site.
