Patent number: 7735553Abstract: A snap-lock bushing is provided for use with prepacked screens for monitoring wells. The bushing has an inner bore for sliding over a tubular well casing member and a raised lip protruding from the inner bore for engaging corresponding grooves at each end of the well casing member. The raised lip includes a plurality of lip segments with gaps or slots formed between the lip segments, which allow the raised lip to flex outward during assembly. A prepacked screen is assembled using a snap-lock bushing at each end of the well casing member. A mesh screen is placed in a concentric relationship around the well casing member with the ends of the mesh screen secured over the outer cylindrical surfaces of the bushings. A filter pack of granular material is placed in the concentric space between the well casing member and the screen member during assembly.Type: GrantFiled: June 26, 2007Date of Patent: June 15, 2010Assignee: Kejr Inc.Inventors: Mike B. Carlin, Thomas M. Christy, David W. Cooper, Allen M. Paradis

Publication number: 20100116495Abstract: An expandable tubular to be used within geologic structures and a method of manufacturing thereof are disclosed. The expandable tubular has a substantially tubular shaped member with an axis extending therethrough. The tubular member has one or more helical members formed within a wall of the tubular member, and the helical member may be defined about the axis of the tubular shaped member. Further, a plurality of elongated perforations are formed within the wall of tubular member, and the tubular member is compressible from a larger diameter to a smaller diameter. When compressed, the tubular member stores expansive energy within the wall, in which the tubular member may then expand back to a larger diameter when the expansive energy is released.Type: ApplicationFiled: April 17, 2008Publication date: May 13, 2010Applicant: DYNAMIC TUBULAR SYSTEMS, INC.Inventor: Jeffery A.

Patent number: 7708073Abstract: A screen assembly has a material that conforms to the borehole shape after insertion. The assembly comprises a compliant layer that takes the borehole shape on expansion. The outer layer is formed having holes to permit production flow. The selected conforming material swells with heat, and in one non-limiting embodiment comprises a shape memory foam that is thermoset or thermoplastic. Heat is provided by supplying a fuel (including an oxidant) to a catalyst in close proximity to the compliant layer so that the product from the catalytic reaction is heated steam which contacts and deploys the conforming material. The base pipe can have a screen over it to act as an underlayment for support of the conforming layer or alternatively for screening.Type: GrantFiled: March 5, 2008Date of Patent: May 4, 2010Assignee: Baker Hughes IncorporatedInventors: Bennett M. Richard, Paul M. McElfresh

Patent number: 7708068Abstract: A gravel packing screen with an inflow control device and a bypass. A well screen includes a flow restricting device for restricting inward flow through the screen, and a bypass device for increasing a proportion of the inward flow which passes through the flow restricting device, the bypass device including a material which swells in response to contact between the material and fluid in a well. A method of gravel packing a well includes installing a screen in the well, the screen including a flow restricting device which restricts flow through the screen, and a bypass device for selectively permitting relatively unrestricted flow through the screen; and actuating the bypass device in response to contact between a material of the bypass device and fluid in the well, thereby increasingly restricting flow through the screen. Flow through the flow restricting device and flow through the bypass device may be in parallel.Type: GrantFiled: April 20, 2006Date of Patent: May 4, 2010Assignee: Halliburton Energy Services, Inc.Inventor: Travis T. Hailey, Jr.
