Abstract: A method of assembling a borehole screen assembly includes placing a screen around a base pipe followed by an end ring having a skive cut to allow fitment with the screen by sliding along the skive cut. The assembly can be completed with welds.

Abstract: A wire wrap screen manufacturing method for a given screen diameter involves simultaneous winding of parallel wires that begin in circumferentially offset locations on one end of a perforated base pipe that has circumferentially spaced support rods saves fabrication time. Each of the ends of the wires lie in a common plane to allow fitting an end cap for sealing or to just continuously weld at the ends of the wires to seal the assembly to the base pipe. The spot welds to the support rods occur as the wire is wound over such rods. Equal initial circumferential spacing of the start locations for the wires is preferred although asymmetrical spacing is preferred.

Abstract: A borehole screen such as one with a wire wrap/slip on screen on a base pipe with variable external dimensions features an end ring assembly that is one piece with a skive cut to allow fitment over a screen jacket that covers the wire wrap. The assembly has a cylindrically shaped component to go over the screen jacket and a radial component at one end oriented toward the base pipe. The assembly can be mounted over the base pipe without sliding the assembly over the end of a base pipe due to the skive cut. Relative sliding along the skive cut gets the desired dimension over the screen jacket to control sand inflow followed by the skive cut being sealed with a weld. The radial component is attached to the base pipe such that two welds complete the end assembly of the screen.

Abstract: In one aspect, an apparatus for use in a wellbore is disclosed that in one non-limiting embodiment contains an outer assembly that includes an isolation packer corresponding to each of a plurality of zones along the wellbore, wherein each isolation packer is configured to be set in the wellbore, a release module associated with each isolation packer to release its associated isolation packer after such isolation packer has been set in the wellbore, and a disconnect module below each isolation packer that is armed using a first force and activated using a second force.

Abstract: An apparatus for use in a wellbore includes a string for deployment into the wellbore, the string including at least one packer and an expansion tool downhole of the packer, wherein the expansion tool further includes: a release device and a lock device inside a movable housing; wherein the lock device prevents shifting of the release device until the lock device is moved to an unlock position by application of a first force to the lock device; and wherein the release device is movable to a release position by application of a second force after the lock device has been moved to the unlock position; and wherein the movable housing is capable of moving over the release device after the release device has been moved to the release position to absorb at least one of contraction and expansion of the expansion tool.

Abstract: An apparatus for use in a wellbore is disclosed. The apparatus includes a string for deployment into the wellbore, the string including at least one packer and an expansion tool downhole of the packer. The expansion tool further includes: a release device and a lock device inside a movable housing; wherein the lock device prevents shifting of the release device until the lock device is moved to an unlock position by application of a first force to the lock device. The release device is movable to a release position by application of a second force after the lock device has been moved to the unlock position. The movable housing is capable of moving over the release device after the release device has been moved to the release position to absorb at least one of contraction and expansion of the expansion tool.

Abstract: A filtering assembly is laid flat on an outer shroud. An inner drainage layer is set over the filtering assembly while laid flat such that the inner drainage layer overlaps the filtering assembly. The inner drainage layer is sealed and secured to the outer shroud by diffusion bonding or welding while overlaying the filtering assembly. With the filtering assembly held firm between the inner drainage layer and the outer shroud a spiral winding procedure is commenced to roll the flat assembly into a cylindrical shape. The edges are sealed by welding or diffusion bonding. The spiral winding and seam closure can be done on a perforated base pipe or the base pipe can be inserted into the finished assembly at a later time and secured. Alternatively the filtering assembly and outer shroud, with or without the drainage layer can be wound over a perforated base pipe or a complete screen assembly.
