Hydraulic fracturing in kerogen-rich unconventional formations

A system for hydraulic fracturing comprising:

• a control system comprising one or more processors;
• and
• a non-transitory computer-readable medium storing instructions executable by the one or more processors to perform operations comprising:
• receive a first value representative of a volume of kerogen breaker in a fracturing fluid;
• determining a discrete fracture network (DFN) comprising:
• a description of a number of fractures, wherein each fracture is characterized by one or more of length, width, height, and orientation that are estimated based on a hydraulic fracture model;
• and
• predicted effects of the volume of kerogen breaker represented by the first value on initiation and propagation of the fractures and sustainability of the fractures during hydrocarbon extraction;
• determining a first hydrocarbon production volume value, by a geomechanical model based on the DFN;
• determining a second hydrocarbon production volume value, by a reservoir model based on the DFN;
• determining an third estimated hydrocarbon production volume based on the determined first hydrocarbon production volume value and the determined second hydrocarbon production volume value;
• adjusting, by an adjustment module, the first value based on the determined third estimated hydrocarbon production volume;
• controlling, by the control system, a valve to adjust a volume of kerogen breaker in the fracturing fluid based on the adjusted first value;
• and
• providing, based on the controlling, the adjusted volume of kerogen breaker in the fracturing fluid to a hydrocarbon reservoir in a subterranean zone, wherein shale stiffness and strength properties in the hydrocarbon reservoir are modified based on the adjusted volume of kerogen breaker such that the third estimated hydrocarbon production volume is predictive of a volume of hydrocarbon extracted from the hydrocarbon reservoir based on the modified shale stiffness and strength properties in the hydrocarbon reservoir.
