Patent number: 7048048Abstract: An expandable sand control screen (100) that is positionable within a wellbore comprises a fluid permeable generally tubular member (102) that is expanded downhole. A filtering assembly is disposed exteriorly of the generally tubular member (102). The filtering assembly includes a filter medium (106) that prevents the flow of particulate material of a predetermined size therethrough but allows the flow of production fluids therethrough. The filtering assembly also includes a compliable member (118) that has a thickness that is radially variable downhole. During or after expansion of the expandable sand control screen (100), the radial variability of the thickness of the compliable member (118) allows the expandable sand control screen (100) to comply with any irregularities in the wellbore profile, thereby preventing any void regions between the expandable sand control screen (100) and the wellbore.Type: GrantFiled: June 26, 2003Date of Patent: May 23, 2006Assignee: Halliburton Energy Services, Inc.Inventors: Philip D. Nguyen, Jimmie D. Weaver, Johnny A. Barton, R. Ashley Donaldson, Alex Procyk, Jackie M. LaFontaine, Ralph H. Echols, Perry C. Shy, Timothy E. Harms, Gregory B. Chitwood

Patent number: 6994170Abstract: A sand control screen assembly (60) comprises a base pipe (62) having at least one opening (64) that allows fluid flow therethrough and a filter medium (66) positioned about the exterior of the base pipe (62) that allows fluid flow therethrough and prevents particulate flow therethrough. An inflatable seal member (72) is disposed within the at least one opening (64) of the base pipe (62) and controls fluid flow through the at least one opening (64). An inflation fluid source (74) is in fluid communication with the inflatable seal member (72) and provides an inflation fluid to the inflatable seal member (72) to selectively urge the inflatable seal member (72) into sealing engagement with the at least one opening (64).Type: GrantFiled: May 29, 2003Date of Patent: February 7, 2006Assignee: Halliburton Energy Services, Inc.Inventor: Ralph H.

Patent number: 6941652Abstract: An expandable well screen has a desirable thin-wall construction together with a simplified fabrication method. In fabricating the screen, a flexible sheet of metal mesh filter media is diffusion bonded to an inner side of a perforated metal sheet which is then deformed to a tubular shape to form a filter structure having an outer perforated tubular shroud interiorly lined with the filter media. The tubular filter structure is telescoped onto a perforated base pipe and has its opposite ends sealingly secured thereto to complete the expandable well screen.Type: GrantFiled: July 2, 2002Date of Patent: September 13, 2005Assignee: Halliburton Energy Services, Inc.Inventors: Ralph H. Echols, Anthony D. Simone, Sam A. Hopkins

Patent number: 6899176Abstract: A sand control screen assembly (40) and method for treating formations traversed by a wellbore (34) in a single trip are disclosed. The sand control screen assembly (40) includes a base pipe (56) with a plurality of openings (58) that allow fluid flow therethrough. A filter medium (62) is positioned about the exterior of the base pipe (56) to filter particulate matter out of the production fluids. One-way valves (70) are operably associated within the openings (58) of the base pipe (56) to prevent fluid flow from the interior of the base pipe (56) to the exterior of the base pipe (56) during a treatment process. The one-way valves (70), however, are actuatable to allow fluid flow from the exterior of the base pipe (56) to the interior of the base pipe (56) to allow production of fluids from the formation (14).Type: GrantFiled: November 13, 2002Date of Patent: May 31, 2005Assignee: Halliburton Energy Services, Inc.Inventors: Travis T.

Patent number: 6854521Abstract: A well completion system for creating a seal between a production tubing (30) and a well casing (34) positioned within a wellbore (32) comprises a production packer (46) that includes a section of the production tubing (30) and at least one seal element (60). The production tubing (30) is then positioned within the well casing (34) that lines the wellbore (32). An expander member (56) that is positioned within the production tubing (30) then travels longitudinally through the production packer (46) to expand the section of the production tubing (30) downhole that includes the seal element (60). This expansion creates a sealing and gripping relationship between the production tubing (30) and the well casing (34).Type: GrantFiled: March 19, 2002Date of Patent: February 15, 2005Assignee: Halliburton Energy Services, Inc.Inventors: Ralph H.

Patent number: 6854522Abstract: The present disclosure addressed apparatus and methods for forming an annular isolator in a borehole after installation of production tubing. Annular seal means are carried in or on production tubing as it is run into a borehole. In conjunction with expansion of the tubing, the seal is deployed to form an annular isolator. An inflatable element carried on the tubing may be inflated with a fluid carried in the tubing and forced into the inflatable element during expansion of the tubing. Reactive chemicals may be carried in the tubing and injected into the annulus to react with each other and ambient fluids to increase in volume and harden into an annular seal. An elastomeric sleeve, ring or band carried on the tubing may be expanded into contact with a borehole wall and may have its radial dimension increased in conjunction with tubing expansion to form an annular isolator.Type: GrantFiled: September 23, 2002Date of Patent: February 15, 2005Assignee: Halliburton Energy Services, Inc.Inventors: Michael M.

Publication number: 20040035591Abstract: A fluid flow control device (136) for use in a wellbore to control the inflow of production fluids comprises a tubular member (134) having at least one fluid passageway (136) and a sand control screen (132) positioned exteriorly therearound. The sand control screen (132) has a filter medium section (142) that defines a first annular region (144) with the tubular member (134) and a housing section (146) that defines a second annular region (148) with the tubular member (134) adjacent to the fluid passageway (136). A sealing member (150) is positioned within the second annular region (148). A hydraulic pressure source (152) is selectively in fluid communication with the sealing member (150) to operate the sealing member (150) from a nonsealing position wherein fluid flow through the fluid passageway (136) is allowed, to a sealing position wherein fluid flow through the fluid passageway (136) is prevented.Type: ApplicationFiled: May 27, 2003Publication date: February 26, 2004Inventor: Ralph H.

Publication number: 20040020832Abstract: A sand control screen assembly (200) positionable within a production interval of a wellbore that traverses a subterranean hydrocarbon bearing formation comprises a base pipe (202) having openings (204) in a sidewall section thereof that allow fluid flow therethrough. A filter medium (210) is positioned about the exterior of at least a portion of the base pipe (202). The filter medium (210) selectively allows fluid flow therethrough but prevents the flow of particulate of a predetermined size therethrough. A seal member (218, 220, 222) is operably associated with the base pipe (202). The seal member (218, 220, 222) has a one-way valve configuration and a valve open configuration such that the seal member (218, 220, 222) controls fluid flow through the openings (204) of the base pipe (202).Type: ApplicationFiled: April 25, 2003Publication date: February 5, 2004Inventors: William Mark Richards, Travis T.

Patent number: 6540025Abstract: Initially, a set of locking lugs lock an inner mandrel is locked in position with respect to an outer mandrel. Unlocking the travel joint is accomplished by applying a constant vertical or downward force on the tubing string. That vertical force is transmitted through the tubing string to the outer mandrel, which causes hydraulic pressure with a hydraulic chamber to increase. When the hydraulic pressure exceeds a pressure threshold, a pressure sensitive valve opens, and the hydraulic fluid gradually flows into a reserve hydraulic chamber, allowing the outer mandrel to move with respect to the inner mandrel. A viscosity independent flow restrictor limits the transfer of hydraulic fluid to a preset flow rate. After sufficient hydraulic fluid has been received into the reserve chamber, the outer mandrel aligns with the locking lugs, which then move from the locked position to the unlocked position. The travel joint then releases, allowing the outer mandrel to telescope inward and outward.Type: GrantFiled: October 24, 2001Date of Patent: April 1, 2003Assignee: Halliburton Energy Services, Inc.Inventors: Gordon K.
