Abstract

A method for performing a fracturing operation in a subterranean formation of a field. The method includes obtaining, during the fracturing operation, distributed optical fiber data from a downhole sensor of a treatment well in the subterranean formation, and determining, based on the distributed optical fiber data, an active perforation location from a number of pre-determined perforation locations of the treatment well. The active perforation location is a location of fluid flow into the subterranean formation during the fracturing operation. The method further includes generating, based at least on the active perforation location, a fracturing model for the subterranean formation, and performing, based on the fracturing model, modeling of the fracturing operation to generate a modeling result.

2. The method of claim 1 , further comprising:

determining, based at least on the distributed optical fiber data, a micro-seismic event location of the fracturing operation.

3. The method of claim 2 , further comprising:

obtaining, during the fracturing operation, monitoring well data from at least one downhole sensor of a monitoring well in the subterranean formation, wherein determining the micro-seismic event location is further based on the monitoring well data.
