Real-Time Fracture Monitoring, Evaluation And Control

A method for real-time monitoring and evaluation of fractures during a hydraulic fracturing operation, the method comprising:

• selecting slurry rate data and borehole heel pressure data;
• interpolating and aligning the slurry rate data and the borehole heel pressure data with respect to time;
• determining a matching filter for the slurry rate data and the borehole pressure data;
• inverting parameters of a model that is based at least on resistance, inductance, and capacitance, wherein the parameters are based on the matching filter and a response of the model;
• obtaining operational indicators from an inversion of the parameters;
• and
• controlling a slurry flow rate into a wellbore based on the operational indicators for the hydraulic fracturing operation.

A hydraulic fracturing system comprising:

• a frac tank;
• a pump in fluid communication with the frac tank;
• a sensor configured to measure a property in a wellbore;
• and
• a system controller in communication with the pump and the sensor, the system controller configured to:
• receive signals from the sensor and estimate a dimension of a dominant fracture propagating from the wellbore;
• invert parameters from a model based on resistance, inductance, and capacitance, wherein the signals are inputs for the model;
• and
• control the pump based on the estimate of the dimension of the dominant fracture or operational indicators.
