Abstract
The present disclosure relates, according to some embodiments, to apparatus, systems, and methods of fracturing a geological structure including the application of kinetic energy (e.g., from high velocity frack fluid) to a subterranean structure. In some embodiments, the present disclosure relates to apparatus, systems, and methods for delivery of high velocity fluid to a well using a down hole valve and/or throttling system. The present disclosure relates to apparatus, systems, and methods of generating pressure using accumulators (e.g., high pressure accumulators) at the surface of a well.
Claims20
A method of kinetically fracking a subterranean structure, the method comprising:
- (a) providing a fracking string inside a perforated wellbore liner having an interior cavity, the fracking string having an interior channel and spaced-apart apertures connecting the interior string channel and the liner cavity, comprising the steps of:
- (i) providing a fracking fluid at a pressure of about 8,000 psi to about 15,000 psi, wherein the fracking fluid is substantially free of proppant;
- (ii) adding at least one proppant to the fracking fluid;
- and
- (iii) injecting the fracking fluid with proppant into the interior channel;
- (b) accelerating the fracking fluid in the interior channel in a downhole direction to a velocity of from about 10 to about 150 feet per second;
- and
- (c) abruptly decelerating fracking fluid flow.
