Abstract

Systems and methods 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, to obtain inverted parameters, from a model based on resistance, inductance, and capacitance, wherein the signals are inputs for the model;
control the pump based on the estimate of the dimension of the dominant fracture or operational indicators;
select slurry rate data and borehole heel pressure data; and
interpolate and align the slurry rate data and the borehole heel pressure data with respect to time.

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 a local window for the slurry rate data and the borehole heel pressure data for processing.

5. The system of claim 4 , wherein the system controller is further configured to determine a matching filter between the slurry rate data and the borehole heel pressure data.

6. The system of claim 5 , wherein the system controller is further configured to invert the parameters from the model based on the matching filter and a response of the model.

7. The system of claim 6 , wherein the system controller is further configured to obtain the operational indicators from the inverted parameters.

8. The system of claim 7 , wherein the operational indicators are indicative of a hydraulic fracturing operation.

9. The system of claim 8 , wherein the system controller is further configured to control the pump based on the operational indicators.

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

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

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

13. 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;
control the pump based on the estimate of the dimension of the dominant fracture or operational indicators; and
input the signals into the model comprising a first resistor, a second resistor, an inductor, and a capacitor, 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 13 , wherein the system controller is further configured to obtain the operational indicators from the inverted parameters.

19. The system of claim 18 , wherein the operational indicators are indicative of a hydraulic fracturing operation.

20. The system of claim 19 , wherein the system controller is further configured to control the pump based on the operational indicators.
