Publication number: 20200318465Abstract: A perforating tool assembly may be modularized by providing modular charge segments to provide for multiple configurations of shaped charges without the requirement of excess inventory. The modular charge segments may comprise any number of modular charge holder segments and modular charge spacer segments which are configured to provide for different spacings and offsets of shaped charges disposed within the modular charge holder segments. The modular charge holder segments include slots and locking tabs to allow for the differing offsets between charges. The modular charge holder segments may comprise a slit that allows the modular holder segment to be flexed or deflected to permit the loading and downloading of shaped charges. The modular charge segments may comprise a plastic or rubber material to provide for safer deployment of shaped charges downhole.Type: ApplicationFiled: June 22, 2020Publication date: October 8, 2020Inventors: Scott Randall Von Kaenel, Richard Ellis Robey

Publication number: 20200263514Abstract: A system and method of controlling a dynamic time-pressure profile associated with a perforation event that includes extending a perforation assembly within a casing string; firing a perforation gun of the perforation assembly; measuring, using a sensor of the perforation assembly, pressure within the casing string, wherein the measured pressure forms the dynamic time-pressure profile; identifying a first measured pressure within the dynamic time-pressure profile; identifying, using a controller of the perforation assembly, a first difference between the first measured pressure and a first reference pressure; and adjusting, using a first pressure generator of the perforation assembly, the pressure in response to the first difference to control the dynamic time-pressure profile; wherein the sensor, the controller, and the first pressure generator provide a feedback control loop.Type: ApplicationFiled: January 27, 2016Publication date: August 20, 2020Inventors: Richard Ellis Robey, James Marshall Barker, Kuo-Chiang Chen

Publication number: 20200088013Abstract: An apparatus and method according to which a perforating gun includes a volume fill body. The volume fill body is positioned in the space between a charge tube and a carrier tube. The fill body occupies at least part, and sometimes all, of the free volume space between the charge tube and carrier tube thereby reducing the free volume space. In certain downhole applications, large free volume space can lead to significant reductions in wellbore pressure, causing dynamic underbalance, which is undesirable. The presence of the volume fill body prevents, or at least reduces, dynamic underbalance and its effects. Also, the volume fill body aligns the charge tube with the carrier tube, further assisting perforation.Type: ApplicationFiled: July 12, 2019Publication date: March 19, 2020Inventors: Brenden Michael Grove, Richard Ellis Robey, Christopher C. Hoelscher

Publication number: 20190368320Abstract: An apparatus comprises a first cluster of perforator guns positioned circumferentially around a central longitudinal axis at a first axial position, wherein the first cluster is configured in a closed position while the apparatus is being lowered to a perforator position in a wellbore. After the apparatus is lowered to the perforator position, the first cluster is to move to an expanded position such that the perforator guns are moved closer to a target that is to be perforated.Type: ApplicationFiled: April 19, 2017Publication date: December 5, 2019Inventor: Richard Ellis Robey

Patent number: 10415353Abstract: A perforating gun apparatus for use in a wellbore comprising at least one explosive component and a disintegration-resistant porous material. The disintegration-resistant porous material minimizes fluid shock propagation from a perforated reservoir resulting from the inrush of fluid and debris. A system and method of minimizing fluid shock propagation effects in a perforating gun apparatus using a disintegration-resistant porous material to attenuate fluid pressure waves during a perforation operation in a subterranean well.Type: GrantFiled: May 6, 2015Date of Patent: September 17, 2019Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Richard Ellis Robey, Allan Zhong, Wesley Neil Ludwig, Christopher C.

Publication number: 20190271214Abstract: An apparatus comprises a first cluster of perforator guns positioned circumferentially around a central longitudinal axis at a first axial position. The apparatus includes a second cluster of perforator guns positioned circumferentially around the central longitudinal axis at a second axial position. The first and second clusters are configured in a closed position while the apparatus is being lowered to a perforator position in a wellbore. After the apparatus is lowered to the perforator position, the first and second clusters are to move to an expanded position and the first cluster is to move axially such that the first cluster and the second cluster at least partially overlap.Type: ApplicationFiled: February 3, 2017Publication date: September 5, 2019Inventors: Richard Ellis Robey, Christopher C. Hoelscher

Patent number: 10208573Abstract: An apparatus comprising a charge tube for a perforating gun assembly used in harvesting energy in a wellbore and a retaining projection formed on an end of the charge tube. When the charge tube is inserted into a gun body, the retaining projection engages with the gun body of the perforating gun assembly to restrict movement of the charge tube with respect to the gun body when engaged with the gun body. The retaining projection can comprise a plurality of collet fingers on an end of the charge tube that engage with the gun body to longitudinally retain the charge tube. The retaining projection can comprise at least one alignment finger that limits radial movement of the charge tube with respect to the gun body. The retaining projection can comprise a plurality of centralizing bend tabs that restrict radial movement of the charge tube when inserted into the gun body.Type: GrantFiled: September 10, 2014Date of Patent: February 19, 2019Assignee: HALLIBURTON ENERGY SERVICES, INC.Inventors: Scott Von Kaenel, Richard Ellis Robey, Marcelo Jorge Laxalt

Patent number: 10082008Abstract: In accordance with embodiments of the present disclosure, a perforating system for perforating a subterranean formation includes a carrier gun body having a cylindrical sleeve. The perforating system also includes a charge holder disposed in the cylindrical sleeve and a plurality of charges disposed on the charge holder. The charge holder is dissolvable in at least one wellbore fluid delivered through the carrier gun body after detonation of the charges. The charges may also be dissolvable during or after detonation. In some embodiments, the carrier gun body is dissolvable wellbore fluid delivered through the carrier gun body. By including dissolvable parts, the disclosed perforating gun yields relatively lower amounts of debris in the wellbore after detonation. In addition, the dissolving portions of the perforating gun allow the remaining portions of the gun to be used to perform wellbore operations downhole without pulling the perforating gun.Type: GrantFiled: August 6, 2014Date of Patent: September 25, 2018Assignee: Halliburton Energy Services, Inc.Inventors: Richard Ellis Robey, Christopher Hoelscher, Michael Fripp
