The objective of this project has been to identify, locate, and characterize in-situ fractures using downhole and surface seismic methods, the goal being to estimate the permeability of these fractures from the way that seismic waves interact with them. The work proposed under the renewal of this grand for the period of 1993--1996 included four specific areas of research. First was the use of full waveform acoustic logs and shear wave logs to characterize in-situ fractures. The second was the use of laboratory ultrasonic scale models to verify the effects of fractures and anisotropy on acoustic and shear logs. Third, the authors proposed to study methods of monitoring hydrofractures with passive seismic techniques. Finally, the authors planned to study the effect of rough fracture surfaces on fluid flow.
