Inversion Method to Estimate Fracture Propagation Velocity and Fracture Volume with Cross-Well Distributed Fiber-Optic Strain Data before Fracture Hit

Systems and methods are provided to obtain fracture parameters of a hydraulic fracturing operation using strain data obtained before a fracture hit. A system may include a strain sensor and processing circuitry. The strain sensor may be disposed downhole in a monitoring well and may obtain strain data while a fracture caused by a hydraulic fracturing operation propagates from a treatment well toward the monitoring well before a fracture hit occurs in the monitoring well. The processing circuitry may perform an inversion based on the strain data to estimate fracture parameters associated with the propagation of the fracture before the fracture hit.
