Modeling hydraulic fracturing induced fracture networks as a dual porosity system

A system for calibrating fracture networks, comprising:

• a fracture network characterization tool configured to:
• estimate an average fracture width of a fracture network using one or more of net fracturing pressure, Poisson's ratio, shear modulus and fracture height;
• determine microseismic event envelope and base intensity data using a three-dimensional geomodel comprising microseismic event data;
• determine hydraulic fracturing treatment (HFT) fracture intensity of post-hydraulic fracturing treatment (post-HFT) based on the average fracture width and HFT volume data;
• calibrate the base intensity data to the HFT fracture intensity to obtain calibrated HFT fracture intensity;
• determine a proppant transportation and distribution scenario;
• and
• generate a dual porosity reservoir model based on the calibrated HFT fracture intensity and the proppant transportation and distribution scenario;
• and
• a surface unit comprising a processor and configured to:
• perform field operations based on the dual porosity reservoir model.

A computer readable storage medium storing instructions for calibrating fracture networks, the instructions when executed causing a processor to:

• estimate an average fracture width of a fracture network using one or more of net fracturing pressure, Poisson's ratio, shear modulus and fracture height;
• determine microseismic event envelope, microseismic event intensity, and natural fracture intensity using a three-dimensional geomodel comprising microseismic event data;
• determine hydraulic fracturing treatment (HFT) fracture intensity of post-hydraulic fracturing treatment (post-HFT) based on the average fracture width and HFT volume data;
• calibrate the base intensity data to the HFT fracture intensity to obtain calibrated HFT fracture intensity;
• and
• generate a dual porosity reservoir model based on the calibrated HFT fracture intensity.
