Title: Continuous monitoring of crosswell seismic travel time

Conference ·
OSTI ID:923194

In two separate shallow field experiments, at two distancescales, we have used continuous monitoring to estimate the effect ofbarometric pressure on crosswell travel time and thereby calibrated thestress sensitivity of the rock volume between the wells. In a 3 mexperiment we found a stress sensitivity of 10-6/Pa while in a 30 mexperiment the sensitivity was 5 x 10-8 /Pa. Results from a deeper (1km), 2 month experiment at the San Andreas fault observation boreholeswill be presented if analysis is completed.
