Publication number: 20180187514Abstract: A ball valve is disclosed that includes a valve housing, a first seat surface having a first inner diameter and a first outer diameter, and a second seat surface having a second inner diameter and a second outer diameter. The second inner diameter is larger than the first outer diameter, and may be separated by a channel. A resilient seat surface may be disposed within the channel. The valve further includes a ball that is rotatably movable within the housing and that contacts at least one of the first seat surface and the second seat surface to form a seal.Type: ApplicationFiled: April 20, 2016Publication date: July 5, 2018Applicant: Halliburton Energy Services, Inc.Inventors: Peter Derek Walter Inglis, Ralph Harvey Echols, III

Patent number: 9726004Abstract: A wellbore system can include a completion assembly having a completion string. The system can also include a service string that can be positioned within an inner diameter of the completion string. A location-sensing component can be positioned on the completion string or the service string. A communication link communicatively coupled with the location-sensing component can transmit signals representing a stimuli detected by the location-sensing component. A stimuli-producing device can output the stimuli that is detected by the location-sensing component. A stimuli-producing device can be positioned on the other of the completion string or the service string.Type: GrantFiled: November 5, 2013Date of Patent: August 8, 2017Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Ralph Harvey Echols, III, William Mark Richards

Patent number: 6722427Abstract: The inventions provide apparatus and methods for radially expanding a tubular deployed in a subterranean well by moving an expansion tool axially through the well. An expansion tool apparatus may have wear faces attached to at least a portion of the outer periphery of a mandrel for contacting the interior surface of the pipe, tube, or screen during expansion. According to another aspect of the invention, an expansion tool has a controlled egress seal between the outer surface of the tool and the inside surface of the expandable tubular. According to another aspect of the invention, an automatically variable diameter expansion tool is provided having a variable diameter cone, which expands, and contracts based on input from one or more sensors. According to another aspect of the invention, an apparatus and method for expanding a length of screen assembly in a subterranean wellbore is provided.Type: GrantFiled: October 23, 2001Date of Patent: April 20, 2004Assignee: Halliburton Energy Services, Inc.Inventors: John C. Gano, Kenneth L. Schwendemann, Darrin N. Towers, Ralph Harvey Echols, Perry Carter Shy

Publication number: 20030047311Abstract: A multi-zone packing system having unique features that allow for remote operation, thereby eliminating the need to raise and lower a work string and crossover tool to various zones of interest during a frac pack, gravel pack or related completion procedure. The squeeze pack system has a crossover tool or port collocated with each zone of interest and remotely operated closing devices to allow for the setting of each packer and the packing job to be performed with minimal or no movement of the work string.Type: ApplicationFiled: September 5, 2002Publication date: March 13, 2003Inventors: Ralph Harvey Echols, Phillip T. Thomas, Travis T. Hailey
