Patents by Inventor Kevin Wutherich

Kevin Wutherich has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11326421
    Abstract: A perforating gun system with at least one gun. Each of the perforating guns have charges disposed in a gun carrier that are angled to the longitudinal axis of the gun to achieve a predetermined proppant transport profile into clusters within a stage in a well casing. The perforation tunnels may also have burrs on each side of the casing and acts in initially aiding proppant transport during fracture treatment. A method of tuning a cluster to achieve a desired fracturing treatment based on a feedback from another cluster includes selecting a hole diameter, a hole angle for creating an angled opening, a discharge coefficient, and a proppant efficiency. Moreover, a method of improving perforation charge efficiency.

  • Patent number: 9725987
    Abstract: A method of performing a stimulation operation for a subterranean formation penetrated by a wellbore is provided. The method involves collecting pressure measurements of an isolated interval of the wellbore during injection of an injection fluid therein, generating a fracture closure from the pressure measurements, generating transmissibility based on the fracture closure and a mini fall off test of the isolated interval during the injection, obtaining fracture geometry from images of the subterranean formation about the isolated interval, and generating system permeability from the transmissibility and the fracture geometry. The method may also involve deploying a wireline stimulation tool into the wellbore, isolating an interval of the wellbore and injecting fluid into the interval with the wireline stimulation tool. The fracture geometry may be obtained by imaging the formation, and fracture geometry may be obtained from core sampling.
