    Abstract: A method and apparatus for completing a horizontal hydrocarbon well includes cementing a casing string in the well and creating passages through the casing string adjacent float equipment near the casing toe by slowly dissolving a plug with completion fluid used to pump cement into an annulus between the casing string and bore hole. By the time the cement sets up, the plug dissolves leaving passages in the casing string through which a first frac job may be pumped or which allows pumping perforating equipment into the horizontal leg without requiring a coiled tubing run. The technique can also be used in vertical wells to save a perforating gun run.

  • Patent number: 7681637
    Abstract: A guide shoe that utilizes an eccentric nose attached to a cylindrical body that has spiraled, ridged blades extending outward from the body. An orientation system is attached between the body and a hollow shaft. The orientation system is designed to allow free rotation of the body and nose about the shaft during the insertion of the tubing into the hole. It does this by providing clearance between a pawl and notches on the cylindrical body. Indexing of the eccentric nose is provided by a slight retraction of the tubing string in the well hole. Friction between the well hole and ridged blade causes the cylindrical body to rotate about the shaft and lock into an oriented position. The guide shoe is attached to the tubing string by a threaded female connection mating to the matching male connection on the tubing string.

  • Publication number: 20080110636
    Abstract: A casing shoe for a casing string that includes an annular body. The annular body includes an annular recess that forms an outer portion and an inner portion, the inner portion forming and extending into an inner bore. The annular recess can accept an end of the casing string such that the casing string extends between the inner and outer portions. The annular body includes a homogenous material. The casing shoe is used in a method of guiding a casing string into a wellbore where the casing shoe is attached to an end of the casing string. Attaching the casing string includes inserting the end of the casing string into the annular recess such that the casing string extends between the inner and outer portions. The casing string is then inserted into the wellbore.

  • Publication number: 20080110625
    Abstract: A method and apparatus for cementing an annulus wellbore is described herein. The apparatus includes an internally radiused portion of a sleeve adapted for increasing the compressive strength of a compound for securing a valve in the sleeve. The internally radiused portion prevents the apparatus from leaking during operation. The apparatus is manufactured using one pass of a milling tool. The apparatus is run into a wellbore. A cementing operation in performed past the apparatus. The apparatus then prevents the cement from entering a downhole tubular.

  • Patent number: 7270181
    Abstract: The present invention provides a downhole cementing apparatus run into a borehole on a tubular. The apparatus is constructed on the pipe in such a way that pressure surge during run-in is reduced by allowing fluid to enter the pipe and utilize the fluid pathway of the cement. In one aspect of the invention, an inner member is provided that filters fluid as it enters the fluid pathway. In another aspect of the invention, various methods are provided within the cementing apparatus to loosen and displace sediment in the borehole prior to cementing.

  • Patent number: 7240731
    Abstract: An apparatus to protect the mounting area of casing when subsequently attaching a tubular is disclosed. A sleeve that defines a sealed cavity having a loose incompressible material inside covers the mounting location on the casing. The cementing of the casing takes place through the sleeve. After the cementing, the sleeve is drilled out and the incompressible material is removed to the surface with the drill cuttings. A tubular is inserted in the casing and is preferably expanded into sealing contact with the mounting location on the casing. At the end of expansion, the run in shoe on the tubular is retrieved.

  • Patent number: 7234522
    Abstract: A float system for use in cementing a casing in a wellbore. The wellbore is drilled with a drill bit attached to the casing. The drill bit is removed after the wellbore is drilled. The float system is lowered into the casing after the drill bit is removed. The float system includes a packer apparatus with a float apparatus, preferably a float shoe, attached to the end thereof. The packer apparatus is set in the casing to hold the float shoe in position. A bottom cementing plug is placed in the casing and is urged downwardly until it engages the upper end of the packer apparatus. The cement will flow through the packer apparatus and the float apparatus to fill the annulus between the casing and the wellbore.

  • Patent number: 7219745
    Abstract: An apparatus and methods for preventing the accumulation of unwanted materials in an enlarged inner diameter portion of a casing or housing. In one aspect of the invention, a sleeve is disposed in the housing to isolate an annular area defined by the outer surface sleeve and the wall of the enlarged inner diameter portion. The sleeve prevents unwanted materials from being disposed in the annular area. The sleeve can later be expanded into the enlarged inner diameter portion, removed from the wellbore or destroyed. In another aspect of the invention, the sleeve is provided and disposed to cover the enlarged inner diameter portion. By covering the enlarged inner diameter portion, unwanted material is prevented from accumulating at said portion and from interfering with the expansion of the next casing into said portion to form a monobore. The sleeve can be made from materials that are dissolvable, elastically deformable, or retrievable.

    Abstract: An expandable reamer shoe is provided for use with expandable casing in a borehole. The reamer shoe has a number of reaming members in the form of blades which remain closed against the body of the shoe when inserted through casing, and can then be expanded to underream below the casing. Additionally, the expandable reamer shoe is made substantially of a drillable material so that the borehole can be extended beyond the point reached by the expandable reamer shoe.

  • Patent number: 7036577
    Abstract: A groundwater pumping apparatus includes an outer tube, an inner tube, a shield member, a vacuum unit and a pump unit. The outer tube is buried in ground, and has a water-passing portion at its lower part. The inner tube has a substantially same length as the outer tube, and is placed in the outer tube such that the inner tube is spaced from the outer tube. The inner tube has a groundwater inlet at its bottom end, which is provided at a position lower than a top end of the water-passing portion. The shield member shields top ends of the outer tube and the inner tube. The vacuum unit reduces a pressure in the inner tube. The pump unit pumps groundwater that comes in the inner tube through the groundwater inlet.

  • Patent number: 6810958
    Abstract: An apparatus and method for cementing a casing string in a wellbore. A self-filling tubular cementing collar connected to the lower end of a casing string is provided with one-way flow valving that allows well fluid to enter and self-fill the casing string as it is lowered into the wellbore and automatically prohibits reverse fluid flow from the collar when washing or cementing during forward circulation through the collar. The one-way valving is carried by an axially movable support that can be shifted by a cementing plug moved by pump pressure to permanently seal the entry flow passage after the casing sting is properly positioned in the wellbore.
