Publication number: 20080185157Abstract: A low drag flotation system for placing screens in horizontal wells is provided which includes a screen exterior to the washpipe to be placed for sand control, and hydraulically actuated valves for trapping air within the washpipe. The air in the washpipe creates a buoyancy force that decreases the drag force of the pipe string in the horizontal well, allowing it to move further down the well under its own weight. As a result, screens can be placed in longer lengths of horizontal wells to maximize oil and gas production.Type: ApplicationFiled: February 7, 2008Publication date: August 7, 2008Applicant: BJ Services CompanyInventors: Andrew K.

Publication number: 20080073087Abstract: An underground porosity reservoir includes substantially impermeable barriers and an aquiclude surrounding a volume of alluvial deposits for storing water within the pore spaces of the alluvial deposits. A conduit positioned below a surface layer of the reservoir includes an interior volume that communicates with the pore spaces of the alluvial deposits. An air vent connects the interior volume of the conduit with atmospheric air above the reservoir and allows air to pass to and from the pore spaces of the reservoir. Ventilation of the porosity reservoir provides pressure-relief during reservoir filling operations (when the incoming water would otherwise cause an increase in air pressure within the reservoir), and further provides a vacuum-break as water is extracted from the reservoir (i.e., air from the conduit enters the pore spaces as the water is extracted).Type: ApplicationFiled: September 26, 2007Publication date: March 27, 2008Applicant: PS Systems Inc.Inventors: Stanley R. Peters, Donald O. Summers

Patent number: 5261486Abstract: A method and apparatus for installing a gravel pack well completion wherein flow of fluid in the well can be effectively blocked and excessive hydrostatic pressure can be isolated from the top of a pre-placed column of gravel while an auger-liner assembly is rotated into the gravel. Basically, gravel is first placed within the zone after which a liner is lowered on a workstring and the liner is augered into the pre-placed gravel. A packer cup and by-pass assembly is coupled into the workstring having cup packers which effectively block flow within the well during installation of the liner. The cups are mounted on a rotatably mounted sleeve so that the workstring can be rotated while the cups are expanded against the well casing. The packer cup and by-pass assembly includes a bypass which can be opened after the liner has been placed so that the workstring can easily be withdrawn from the well.Type: GrantFiled: May 4, 1992Date of Patent: November 16, 1993Assignee: Atlantic Richfield CompanyInventors: Holley M. Cornette, Michael H. Johnson, Robert K. Bethel

Patent number: 5190108Abstract: Biological fouling of water wells is inhibited by replacing the air in the well column with an anoxic gas such as nitrogen to deprive aerobic bacteria of oxygen. The anoxic gas is applied from a cylindrical tank at the surface and through a gas pipe extending from the tank down into the well casing. The well casing is sealed near the top to prevent air infiltration and maintain a positive gas pressure. The anoxic gas is applied at a slightly positive pressure to maintain the well column filled with it and to prevent air penetration. The gas can be supplied to the well column only or to both the well column and the aquifer so that a blanket of gas in the area of the well inhibits air penetration of the water from the unsaturated cover layer above the aquifer.Type: GrantFiled: August 19, 1991Date of Patent: March 2, 1993Assignee: Layne-Western Company, Inc.Inventor: Neil Mansuy

Patent number: 5036920Abstract: A method and apparatus for installing a gravel pack completion which does not require the circulation of fluids during installation. The gravel is first placed or preset within the completion zone and then a well completion tool (e.g. a fluid-permeable liner) having an auger blade thereon is lowered and rotated into the present gravel without circulating fluid through the tool. Since the auger blade mechanically displaces the gravel upward as the tool is moved into the preset gravel, there is no need to flow fluid under pressure to "fluidize" the gravel as is required in prior completions of this type.Type: GrantFiled: May 4, 1990Date of Patent: August 6, 1991Assignee: Atlantic Richfield CompanyInventors: Holley M. Cornette, Michael H. Johnson, Bennett M. Richard

Patent number: 5033551Abstract: A method and apparatus for sealing a well annulus, the apparatus comprising a resilient sealing element molded in a upwardly oriented frustro-conical form affixed to a packer body. A running tool is mated with the packer body, the running tool having an internal bore adapted to collapse the sealing element to the diameter of the internal bore. The packer body is mated with a tubing screen by right hand threads and the running tool, packer body and tubing screen lowered into a well casing at the end of a pipe string. The well seal is activated when the pipe string is rotated in a clock-wise direction, disengaging and withdrawing the running tool and releasing the skirt which expands to seal with the internal walls of the casing.Type: GrantFiled: May 25, 1990Date of Patent: July 23, 1991Inventor: Charles A.

Patent number: 4497370Abstract: Apparatus and method for recovery of liquid hydrocarbons on ground water in which one or more perforate, small diameter (2 to 4 inch) well casings are installed in the ground in or at least adjacent to a contaminated soil area containing the liquid hydrocarbons. A liquid recovery unit is in each well casing and each recovery unit has a hollow housing covered by a semi-permeable membrane which passes liquid hydrocarbons but blocks the flow of ground water into the housing. The liquid hydrocarbons collected in the housings can be moved to a receiver by pressurizing the housings, by suction applied to the housings, by pressurizing the well casings, and by the use of submersible pumps near the housings. Several embodiments of the recovery units are disclosed.Type: GrantFiled: August 12, 1982Date of Patent: February 5, 1985Inventor: Michael K. Breslin
