Multipole moment decomposition for imaging hydraulic fractures from remote elastostatic data
2007
Inverse Problems
Hydraulic fracturing involves the propagation of a fracture in brittle rock by the intrusion of a high pressure viscous fluid. There is considerable interest in identifying characteristics of these evolving underground fractures via the passive monitoring of remote elastostatic deformations. In this paper, we present a far-field multipole expansion procedure to identify the harmonic moments of the fracture. The harmonic moments are related to fundamental quantities such as fracture volume and
