Real-time diversion control for stimulation treatments using fiber optics with fully-coupled diversion models

A system comprising:

• at least one processor;
• and
• a memory coupled to the processor having instructions stored therein, which when executed by the processor, cause the processor to perform a plurality of functions, including functions to:
• obtain real-time measurements from a plurality of fiber-optic data sources at a well site during a stimulation treatment being performed along a portion of a wellbore within a subsurface formation, the real-time measurements including Distributed Acoustic Sensing (DAS) measurements, Distributed Temperature Sensing (DTS) measurements, and Distributed Strain Sensing (DSS) measurements;
• determine fracture growth and stress within the subsurface formation surrounding the portion of the wellbore as the stimulation treatment is performed, based on the real-time measurements and a fully-coupled diversion model, the fully-coupled diversion model including a wellbore model and a geomechanical model of the subsurface formation;
• determine an amount of diverter for a diversion phase of the stimulation treatment to be performed along the portion of the wellbore, based on the fracture growth and the stress within the subsurface formation;
• and
• perform the diversion phase of the stimulation treatment by injecting the amount of diverter into the subsurface formation via at least one injection point located along the portion of the wellbore.
