  • the presence of the wiper plug within the casing sting after the cementation operation may hinder the ability to perform subsequent fluid circulation operations, e.g., which may be used for enabling tools to be pumped downhole.
  • systems such as drillable wiper plugs have been devised to enable the wiper plugs to be removed, and work sufficiently for their intended purpose, the industry would well receive alternative wiper plug systems.
  • a wiper plug including a body having one or more wiping elements radially extending therefrom; and an obstructing portion disintegrable upon exposure to a selected fluid in order to permit fluid communication across the wiper plug when the obstructing portion is disintegrated.

  • FIG. 1 a completion system 100 for performing a downhole cementing operation is schematically illustrated. Specifically, an annulus 102 located radially between a casing string 104 and a borehole 106 is intended to be cemented by use of the system 100.
  • the casing string 104 includes a liner 108 that is hung from a relatively up-hole portion of the casing 104 and is also cemented.
  • the casing string 104 includes a shoe 110 permitting communication of cement and other fluids between the casing string 104 and the annulus 102.
  • the shoe 110 can be equipped with one or more floats or check valve devices, e.g., as a so-called float shoe, to permit fluid flow in primarily one direction, e.g., to prevent the cement or other fluids from entering the casing string 104 from the annulus 102.
  • a float collar 112 can also be included having one or more floats or other check valve devices for a similar purpose.
  • Cement can be supplied via a running string 114 that is insertable into the casing string 104.
  • a wiper plug 10 can be pumped through the running string 114.
  • the wiper plug 10 may also be referred to as a pump down plug or wiper dart.
  • a pressurized fluid can be supplied to the up-hole side of the wiper plug 10 to propel the plug 10 through the running string 114, thereby displacing the cement downhole of the plug 10 as the plug 10 progresses through the running string 114 and/or the liner 108.

  • the wiper plug 10 includes one or more wiper elements 12 that sealingly engage the walls of the running string 114.
  • the wiper plug 10 is arranged to prevent fluid communication across the plug 10, e.g., in both the up-hole and downhole directions. That is, the engagement of the wiper elements 12 within the running string 114 facilitates the ability of pressurized fluid to propel the plug 10 downhole as well as to urge cement and other fluids (e.g., spacer fluid separating the cement and the wiper plug 10) in the downhole direction while preventing the cement or other fluids from flowing back up-hole across the plug 10.

In this way, the obstructing portion 16 enables pressurized fluid to propel the plug 10 through the running string 114 and prevents cement from flowing up-hole past the plug 10, as noted above.
  • a liner wiper 116 is included at the end of the running string 114.
  • the plug 10 is configured to land in and sealingly engage the liner wiper 116.

  • the wiper plug 10 is sealingly engaged with the liner wiper 116, and the liner wiper 116 sealing engaged with the liner 108, thereby blocking fluid flow through these components and hindering the ability to pump fluid through the casing string 104.
  • the obstructing portion 16 of the plug 10 is disintegrable upon exposure to a selected fluid in order to remove the obstructing element 16 from the fluid passage 14 and thereby permit fluid to flow through the plug 10 via the passage 14.
  • disintegrable refers to a material or component that is consumable, corrodible, degradable, decomposable, dissolvable, or otherwise removable in response to the selected fluid. It is to be understood that use herein of the term “disintegrate,” or any of its forms (e.g., “disintegration”, etc.), incorporates the stated meaning.
  • the selected fluid could be a fluid present or naturally occurring within the borehole 106, e.g., a downhole fluid such as brine, water, oil, etc., a fluid that is delivered or pumped downhole specifically for the purpose of disintegrating the obstructing portion 16, e.g., solvents, acids, etc., or combinations thereof.
