Abstract

Systems and methods of the present disclosure generally relate to monitoring, evaluating, and controlling fracture geometry during a hydraulic fracturing operation, in real time. A method comprises measuring a signal representing a condition in a wellbore; inputting the signal into a model for estimating a dimension of a dominant fracture; determining the dimension of the dominant fracture; determining a target dimension for the dominant fracture; and minimizing a difference between the dimension of the dominant fracture and the target dimension in real time, by adjusting at least an injection pressure or flow rate of a hydraulic fracturing fluid into the wellbore.

First claim

What is claimed is:

1 . 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.

2 . The system of claim 1 , wherein the system controller is further configured to input the signals into the model comprising at least one resistor, inductor, or capacitor.

3 . The system of claim 1 , wherein the system controller is further configured to input the signals into a poro-elastic inversion.

4 . The system of claim 1 , wherein the system controller is further configured to select slurry rate data and borehole heel pressure data.

5 . The system of claim 4 , wherein the system controller is further configured to interpolate and align the slurry rate data and the borehole heel pressure data with respect to time.

6 . The system of claim 5 , wherein the system controller is further configured to select a local window for the slurry rate data and the borehole pressure data for processing.

7 . The system of claim 6 , wherein the system controller is further configured to determine a matching filter between the slurry rate data and the borehole pressure data.

8 . The system of claim 7 , wherein the system controller is further configured to invert parameters from the model based on the matching filter and a response of the model.

9 . The system of claim 8 , wherein the system controller is further configured to obtain operational indicators from inverted parameters.

10 . The system of claim 9 , wherein the operational indicators are indicative of a hydraulic fracturing operation.

11 . The system of claim 10 , wherein the system controller is further configured to control the pump based on the operational indicators.

12 . The system of claim 1 , wherein the system controller is further configured to input the signals into the model comprising a first resistor, a second resistor, an inductor, and a capacitor.

13 . The system of claim 12 , wherein the first resistor represents a friction pressure and close pressure for the dominant fracture.

14 . The system of claim 13 , wherein the second resistor represents a net fracture pressure.

15 . The system of claim 14 , wherein the model further comprises a voltage and a current.

16 . The system of claim 15 , wherein the voltage represents a measured pressure.

17 . The system of claim 16 , wherein the current represents a slurry flow rate.

18 . The system of claim 1 , wherein the system controller is further configured to select a local window for slurry rate data.

19 . The system of claim 1 , wherein the system controller is further configured to select a local window for borehole pressure data.

20 . The system of claim 1 , wherein the system controller is further configured to select a local window.
