Patent number: 10107071Abstract: 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 control 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.Type: GrantFiled: November 11, 2015Date of Patent: October 23, 2018Assignee: Weatherford Technology Holdings, LLCInventors: Philip M Snider, Daniel G Purkis

Patent number: 9945211Abstract: A gravel pack assembly for a borehole has first and second joints and a foil. The basepipes of the joints connect end-to-end, and both of the basepipes having filters for filtering fluid passage from a borehole into bores of the basepipes. Transport tubes are disposed along the first and second joint, and a jumper tube expands across the connected ends of the basepipes and connects the transport tubes together. The foil encloses an area across the connected ends. The foil has an external surface defining an annulus thereabout with the borehole. The foil has end rings abutting the filters of the joints. At least a section of the foil leaks fluid from the borehole to the area enclosed by the foil, and at least a filter portion of the assembly filters the leaked fluid from the area to at least one of the first and second bores.Type: GrantFiled: January 22, 2015Date of Patent: April 17, 2018Assignee: Weatherford Technology Holdings, LLCInventors: Stephen McNamee, John S. Sladic, Stephen Reid, Andrew McGeoch, Matthew Manning, Daniel G. Purkis

Patent number: 7145471Abstract: A sequential hydraulic well control system provides actuator selection and operation utilizing pressure applied to hydraulic lines in a sequence. In a disclosed embodiment, an actuation control device of a well control system includes multiple pistons, at least one of which is included in a latch for selectively permitting and preventing displacement of another of the pistons. When one of the pistons displaces in response to pressure applied sequentially to hydraulic inputs of the control device, an associated actuator is placed in fluid communication with the inputs.Type: GrantFiled: April 14, 2000Date of Patent: December 5, 2006Assignee: WellDynamics, Inc.Inventors: Daniel G. Purkis, Michael A. Reid

Patent number: 7013980Abstract: A control system for use in controlling actuation of tools in a subterranean well. In a described embodiment, a control system includes a well tool, an actuator for the well tool and a control module interconnected between the actuator and first and second fluid lines. The control module is operative to meter a predetermined volume of fluid from the actuator to the second line in response to pressure applied to the first line.Type: GrantFiled: August 19, 2003Date of Patent: March 21, 2006Assignee: WellDynamics, Inc.Inventors: Daniel G. Purkis, Alfred R. Curington

Patent number: 6595292Abstract: A method and apparatus for use with two or more hydraulic conduits deployed downhole reduces a number of penetrations required through a well bulkhead for a given number of fluid paths extending therethrough. In a described embodiment, a fluid conductor includes multiple fluid paths extending therein. The fluid conductor is installed in an aperture formed through a bulkhead. Couplings are connected on opposite sides of the bulkhead to opposite ends of the fluid conductor. Multiple hydraulic lines are connected to each of the couplings.Type: GrantFiled: October 12, 2001Date of Patent: July 22, 2003Assignee: Halliburton Energy Services, Inc.Inventors: Daniel G.

Patent number: 6585051Abstract: A hydraulically operated fluid metering apparatus provides discharge of a known volume of fluid to an actuator of a well tool. In one described embodiment, the fluid metering apparatus is connected to a hydraulic input of a well tool actuator. Discharge of the known volume of fluid to the actuator input causes a piston of the actuator to displace a known distance, thereby producing a known increment of actuation of the well tool. The discharge of the known volume of fluid may be repeated to produce a desired total degree of actuation of the well tool.Type: GrantFiled: May 22, 2001Date of Patent: July 1, 2003Assignee: WellDynamics Inc.Inventors: Daniel G. Purkis, Michael A. Reid, Jimmie Robert Williamson, Jr.

Patent number: 6575237Abstract: A system for transmitting hydraulic control signals and hydraulic power to downhole well tools while reducing the number of hydraulic lines installed in the wellbore. Hydraulic control signals can be furnished at relatively lower pressures, and the hydraulic pressure within the line can be selectively increased over a threshold level to provide hydraulic actuation power. The system can provide multiple control paths through a few number of hydraulic lines to provide flexibility and verification of well tool operation. Closed loop hydraulic operation monitors well tool operation, and a combination of pressurized hydraulic lines can provide an operating code for selective downhole well tool control. Four hydraulic lines can provide independent control and actuation of seven well tools, and additional combinations can be constructed.Type: GrantFiled: February 12, 2001Date of Patent: June 10, 2003Assignee: Welldynamics, Inc.Inventors: Daniel G. Purkis, Brett W. Bouldin

Patent number: 6567013Abstract: A well control system and associated method of controlling well tools provides downhole well tool control without requiring the use of electricity or complex pressure pulse decoding mechanisms. In a described embodiment, a digital hydraulic well control system includes multiple well tool assemblies, with each assembly including a well tool, an actuator and an addressable actuation control device. Multiple hydraulic lines are interconnected to each control device. The hydraulic lines transmit addresses or codes to respective selected ones of the control devices, thereby selecting corresponding respective ones of the well tools for actuation thereof. Hydraulic lines are also used to actuate the selected well tools.Type: GrantFiled: February 22, 2000Date of Patent: May 20, 2003Assignee: Halliburton Energy Services, Inc.Inventors: Daniel G.
