order to install a tubing conveyed patch for water shut off the well tool 20 comprises a tubular member 22 attached to a packer 24 which may be an annular gel packer a cross over 26 two wire wrap sand screen elements 28 and a lower packer 30 blank sections 32 of pipe are typically used to properly space the relative positions of each of the components an annulus area 34 is created between each of the components and the wellbore casing 16 the combination of the well tool 20 and the tubular string extending from the well tool to the surface can be referred to as the production string in a typical water shut off operation when multiple wire wrap screens 28 are present the wire wrap screens are typically substantially plugged with fines and water enters the production string through joints in the production string wire wrap sand screens need to be have openings small enough to restrict particulate flow often having gaps in the 60 120 mesh range but other sizes may be used the packer elements 24 30 are set to ensure a seal between the tubular member 22 and the casing 16 a series of tubular patches may be installed via tubular member 22 at joints between the wire wrap screens 28 and blank sections 32 gels or other chemicals.
