Claim 0:
1. A method for determining change in stress in a reservoir formation, comprising:
inducing a pressure pulse in a first well hydraulically connected by a first fracture to the reservoir formation, the pressure pulse inducing tube waves in the first well;
determining a stress-related attribute of the first fracture from tube wave reflection events detected in pressure measurements made in the first well as a result of the inducing the pressure pulse;
determining fluid pressure in the first well;
pumping an hydraulic fracture treatment into the reservoir formation through a second well spaced apart from the first well; and
repeating the inducing and determining the stress related attribute and the determining fluid pressure to estimate changes in the stress-related attribute with respect to time resulting from the pumping the hydraulic fracture treatment through the second well.
