Downhole customization of fracturing fluids for micro-fracturing operations

A system for real-time optimization of micro-fracturing operations, the 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 functions including functions to:
• monitor downhole operating conditions during a micro-fracturing operation along a portion of a wellbore within a subterranean formation, based on downhole measurements collected by sensors of a downhole formation tester communicatively coupled to the computer system and disposed within the wellbore;
• determine injection parameters for a fracturing fluid to be injected from a bulk storage chamber of the downhole formation tester into the subterranean formation, based on the downhole operating conditions;
• transmit to a controller of the downhole formation tester, signals for customizing the fracturing fluid using one or more fluid additives stored within corresponding fluid storage chambers of the downhole formation tester, based on the injection parameters;
• and
• control, using control signals transmitted to the controller of the downhole formation tester during the micro-fracturing operation, injection of the customized fracturing fluid from the downhole formation tester into an area of the subterranean formation surrounding the portion of the wellbore.
