Abstract
Applying shock waves using a plasma pulse generation system or other comparable systems, including an acoustic/pressure oscillatory system, would help to enhance the complexity of the far field hydraulic fracture during fracturing shale formation. It would also help in avoiding pre-mature screen out. The critical factor to maximize the desired results is to apply the shock waves at the correct time. By combining shock wave technology with the newly developed fracturing pressure data analysis, it is possible to achieve maximum results.
Claims11
A method to influence real time propagation of a hydraulic fracture of a wellbore as injection of fracturing fluid occurs during a hydraulic fracturing treatment, the method comprising the steps of:
- commencing injection of fracturing fluid into a wellbore to initiate and propagate a hydraulic fracture;
- monitoring, as the injection of fracturing fluid occurs, hydraulic fracturing treatment pressure or one or more microseismic events generated by the propagating hydraulic fracture;
- analyzing pressure-time data or microseismic event data of the propagating hydraulic fracture;
- determining status of hydraulic fracture propagation from said pressure-time data or microseismic event data;
- creating one or more shock waves from electrical energy;
- and
- applying said shock waves into the injected fracturing fluid inside the wellbore, as the injection of fracturing fluid occurs, for the purpose of creating a longer propped hydraulic fracture and/or enlarging one or more natural fractures intersecting the hydraulic fracture, the number of applications of said shock waves and timing of each application of said shock waves determined by said status of the hydraulic fracture propagation;
- adding one or more metal filament, metal particles, or nanoparticles of element into the fracturing fluid to create one or more secondary shock waves by chemical thermite reaction for the purpose of enhancing far field hydraulic fracture complexity;
- and
- adjusting an amount and type of filament, metal particles, or nanoparticles to control amplitudes of pressure peaks of shock waves created by chemical thermite reaction and distance between pressure peaks of shock waves created by electrical energy and shock waves created by chemical thermite reaction.
