Abstract:
1. A method for determining the location and height of an induced fracture in a subterranean formation comprising: (a) obtaining a pre-fracture data set resulting from: (b) hydraulically fracturing the subterranean formation to generate a fracture with a slurry comprising a liquid and a proppant in which all or a fraction of such proppant includes a thermal neutron absorbing material, the proppant having a thermal neutron capture cross-section of at least about 90 capture units; (c) obtaining a post-fracture data set by: (d) comparing the pre-fracture data set and the post-fracture data set to determine a location of the proppant; and (e) correlating the location of the proppant to a depth measurement of the borehole to determine the location and height of the fracture.
