Patent number: 7650938Abstract: A Residential In-well Internal Water Aerator for reducing/eliminating iron, Hydrogen sulfide, and radon gas is a device that hangs within the well casing. Its support is achieved by the well cap. It is capable of degassing hydrogen sulfide and radon gas and precipitation of the iron to become a solid and attaching its self to the interior walls and drip screens of the Residential In-well Internal Water Aerator within the well, thus reducing/eliminating the stained fixtures, bad smell and the risk of radon gas from within the residence.Type: GrantFiled: October 21, 2005Date of Patent: January 26, 2010Inventors: Thomas G.

Publication number: 20080289815Abstract: A screen assembly that is used with a well includes a base pipe, a screen and ribs. The base pipe has a non-perforated section and has a longitudinal axis. The screen at least partially circumscribes the non-perforated section of the base pipe, and the ribs extend longitudinally in an annular space between the screen and the non-perforated section. A flexible member (e.g., a wire) is wrapped around the ribs. Various other mechanisms may be used instead of the ribs and flexible member in the annular space. In this regard, such annular standoffs such as a corrugated material, a member that has longitudinal channels, and a member formed from a first set of wires that is interwoven with a second set of wires may be used. Alternatively, longitudinal channels may be formed in the outer surface of the base pipe.Type: ApplicationFiled: July 26, 2007Publication date: November 27, 2008Applicant: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Terje Moen, Michael D.

Publication number: 20080142218Abstract: A technique that is usable with a well includes running screen assemblies into the well on a base pipe. Each screen assembly is associated with a different zone of the well to be gravel packed. During gravel packing of the well, the screen assemblies may be selectively configured to contain pressure without running a tool inside the base pipe to form a fluid seal.Type: ApplicationFiled: December 18, 2006Publication date: June 19, 2008Inventors: Gary L.

Patent number: 7195033Abstract: Apparatuses and methods for accurately determining the position of a sliding or rotational sleeve valve in real time are disclosed. The apparatus comprises fiber optic cable based sensors which are either linearly or circumferentially arrayed in the housing that surrounds the sleeve and which can comprise bare cable or cable having fiber Bragg gratings (FBGs). As the sleeve slides or rotates within the housing, the sensors in the arrays are deformed, and this deformation can be correlated to sleeve position by assessing the sensor's reflectivity profiles. Deformation of the sensors is achieved by various mechanical and/or magnetic schemes incorporated into the sleeve.Type: GrantFiled: February 24, 2003Date of Patent: March 27, 2007Assignee: Weatherford/Lamb, Inc.Inventors: Christopher W. Mayeu, Richard M. Wilde, John L. Maida, Jr.

Patent number: 7108060Abstract: Method and apparatus for fracturing different levels of a completion interval in a well. A workstring lowers a fracturing string which, in turn, is comprised of a base pipe which is blank except for perforated sections spaced along its length. Screen may be provided over said sections to block the flow of sand into the base pipe. An alternate flow path (e.g. shunt tubes) extends along the base pipe and has one or more outlets spaced along its length. A slurry is flowed into the annulus surrounding the fracturing string. As liquid is lost from the slurry, sand from the slurry will form bridges at said perforated sections thereby isolating portions of the annulus. Slurry then flows through the shunts tube(s) and out into the isolated portions to fracture the different levels in the completion interval.Type: GrantFiled: September 11, 2003Date of Patent: September 19, 2006Assignee: ExxonMobil Oil CorporationInventor: Lloyd G. Jones

Patent number: 6983796Abstract: A technique for providing auxiliary conduits in multi-trip completions is disclosed. The technique has particular applicability to liner mounted screens which are to be gravel packed. In the preferred embodiment, a protective shroud is run with the gravel pack screens with the auxiliary conduits disposed in between. The auxiliary conduits terminate in a quick connection at a liner top packer. The gravel packing equipment can optionally be secured in a flow relationship to the auxiliary conduits so as to control the gravel packing operation. Subsequent to the removal of the specialized equipment, the production tubing can be run with an auxiliary conduit or conduits for connection down hole to the auxiliary conduits coming from the liner top packer for a sealing connection. Thereafter, during production various data on the well can be obtained in real time despite the multiple trips necessary to accomplish completion.Type: GrantFiled: January 5, 2001Date of Patent: January 10, 2006Assignee: Baker Hughes IncorporatedInventors: Christian F. Bayne, Benn A. Voll, J. Todd Broome, James R. Zachman, Graeme H. Falconer, Michael W. Norris, Edward J. Zisk, Jr., David A. Bilberry, Steve B. Hodges

Patent number: 6896057Abstract: A tubing connection arrangement that includes two expandable tubing sections is disclosed. In one embodiment, each of the tubing sections includes a filter screen sandwiched between inner expandable tubing and outer expandable tubing. On expansion of the tubing sections, the outer tubing provides resistance to radial expansion of the inner tubing in order to ensure that the integrity between the tubing sections is maintained. The filter screen of one of the tubing sections overlaps the filter screen of the other tubing section, and the outer expandable tubing of at least one of the tubing sections extends over the overlapping filter screens.Type: GrantFiled: April 19, 2004Date of Patent: May 24, 2005Assignee: Weatherford/Lamb, Inc.Inventor: Paul David Metcalfe

Patent number: 6857475Abstract: A wellbore completion includes a plurality of longitudinal gravel pack sections disposed within a well, the gravel pack sections being capable of imposing a predetermined substantially radial flow restriction upon fluid production flowing radially through the gravel pack section. At least one of the gravel pack sections creates a radial flow restriction that is different from the radial flow restriction of at least one other gravel pack section. The gravel pack sections may comprise graded gravel material having an effective permeability within a predetermined range when placed in the well.Type: GrantFiled: October 9, 2001Date of Patent: February 22, 2005Assignee: Schlumberger Technology CorporationInventor: Craig David Johnson

Patent number: 6830104Abstract: Improved methods and apparatus for completing a subterranean zone penetrated by a wellbore are provided. The improved methods basically comprise the steps of placing a sand control screen (e.g., screens, screened pipes, perforated liners, prepacked screens, etc.) and an outer shroud assembly mounted over the sand screen in the wellbore adjacent the zone to be completed, the shroud having perforated and blank (non-perforated) segments with the blank segments corresponding to selected intervals of the wellbore, for example problem zones such as shale streaks or isolated zones where flows are restricted by mechanical seals or packers, and injecting particulate material into the wellbore, whereby gravel packing takes place in the remaining length of the wellbore/shroud annulus without voids. The inner annulus between the shroud and screen provides an alternate flow path for the slurry to bypass the blocked intervals and continue with its placement.Type: GrantFiled: August 14, 2001Date of Patent: December 14, 2004Assignee: Halliburton Energy Services, Inc.Inventors: Philip D.

Patent number: 6814139Abstract: A gravel packing apparatus comprises multiple joints each having substantially the same construction and each having a perforated outer tubular (150, 152) positioned around a sand control screen (154, 156) including a slurry passageway (190, 194) and a production pathway (188, 192) therebetween. First and second transition members (210, 204) are disposed at opposite ends of each joint. When two such joints are connected together, the second transition member (204) of one joint is proximate the first transition member (210) of the next joint such that a fluid traveling from the slurry passageway (190) of one joint to the slurry passageway (194) of the next joint travels from the exterior to the interior of the second transition member (204) of the one joint and from the interior to the exterior of the first transition member (210) of the next joint.Type: GrantFiled: October 17, 2002Date of Patent: November 9, 2004Assignee: Halliburton Energy Services, Inc.Inventors: David A.
