Patent number: 10138725Abstract: An apparatus and method for providing a time delay in injection of pressured fluid into a geologic formation. In one aspect the invention is a toe valve activated by fluid pressure that opens ports after a predetermined time interval to allow fluid to pass from a well casing to a formation. The controlled time delay enables casing integrity testing before fluid is passed through the ports. This time delay also allows multiple valves to be used in the same well casing and provide a focused jetting action to better penetrate a concrete casing lining.Type: GrantFiled: August 31, 2015Date of Patent: November 27, 2018Assignee: GEODYNAMICS, INC.Inventors: Kevin R. George, Philip M. Snider, David S. Wesson

Patent number: 10119377Abstract: A dedicated hydraulic line for transmission of a signal device capable of generating one or more unique signals to one or more tools within a subterranean well. Each tool can be equipped with a reader device for receiving signals from and transmitting signals to the signal device. Each reader device can control operation of the tool associated therewith if the reader device is programmed to respond to signals received from the signal device. Hydraulic fluid used to operate the tool can be conveyed via the dedicated hydraulic line or a separate hydraulic line. A separate hydraulic line can be used to reset the tool. Where the tools include sliding sleeves, the tools can be used to hydraulically fracture subterranean environs at spaced apart locations along a well bore in any desired sequence and without removing the tools from the well during the fracturing process.Type: GrantFiled: April 14, 2008Date of Patent: November 6, 2018Assignee: Weatherford Technology Holdings, LLCInventor: Philip M.

Publication number: 20180073341Abstract: Processes and systems for inhibiting the flow of fracturing fluid through one or more subterranean wells offset from the subterranean well being fractured. A fracturing fluid is injected under pressure via a first well penetrating and in fluid communication with a subterranean region of interest so as to fracture the subterranean region. A second fluid is positioned within one or more second subterranean wells penetrating and in fluid communication with the subterranean region. Each second well is equipped with a standing valve that is seated by the second fluid in each second well. The pressure of the second fluid may be monitored and the pressure applied to the second fluid at the surface may be increased upon determining an increase in pressure during the monitoring step.Type: ApplicationFiled: November 14, 2017Publication date: March 15, 2018Applicant: PETROVATIONS LLCInventors: Philip M.

Patent number: 9803455Abstract: A shaped charge comprising a case, a liner positioned within the case, and an explosive filled within the case. The liner is shaped with a subtended angle ranging from 100° to 120° about an apex, a radius, and an aspect ratio such that a jet formed with the explosive creates an entrance hole in a well casing. The jet creates a perforation tunnel in a hydrocarbon formation, wherein a diameter of the jet, a diameter of the entrance hole diameter, and a width and length of the perforation tunnel are substantially constant and unaffected with changes in design and environmental factors such as a thickness and composition of the well casing, position of the charge in the perforating gun, position of the perforating gun in the well casing, a water gap in the wellbore casing, and type of the hydrocarbon formation.Type: GrantFiled: April 7, 2017Date of Patent: October 31, 2017Assignee: GEODYNAMICS, INC.Inventors: Wenbo Yang, Philip M Snider, John T Hardesty, David S Wesson

Patent number: 9752406Abstract: A wellbore plug isolation system and method for positioning plugs to isolate fracture zones in a horizontal, vertical, or deviated wellbore is disclosed. The system/method includes a wellbore casing laterally drilled into a hydrocarbon formation, a wellbore setting tool (WST) that sets a large inner diameter (ID) restriction sleeve member (RSM), and a restriction plug element (RPE). The RPE includes a first composition and a second composition that changes phase or strength under wellbore conditions. After a stage is perforated, RPEs are deployed to isolate toe ward pressure communication. The second composition changes phase to create flow channels in the RPE during production. In an alternate system/method, the second composition changes phase or strength thereby deforming the RPE to reduce size and pass through the RSM's. The RPEs are removed or left behind prior to initiating well production without the need for a milling procedure.Type: GrantFiled: June 5, 2015Date of Patent: September 5, 2017Assignee: GEODYNAMICS, INC.Inventors: John T.
