The method and system describes monitoring and modeling the hydraulic fracturing of a reservoir. The microseismic events caused by hydraulic fracturing on a reservoir are captured by sensor arrays. The data captured by the sensor arrays are then analyzed to determine the source radius, and seismic moment tensor of microseismic events caused by the hydraulic fracturing. This information is then combined with a seismic velocity model to arrive at a discrete fracture network showing at least the orientation, source radius, and source mechanism of each microseismic event. This discrete fracture network is then used to determine the stimulated surface area, stimulated volume, and point of diminishing returns for the hydraulic fracturing process. Hydraulic fracturing engineers can use the algorithms to monitor the well and/or determine well completion. |
