- a sealant sheath surrounding the pipe string functions to prevent the migration of fluids in the annulus, as welt as protecting the pipe string from corrosion.
- Sealant compositions also may be used in. remedial-cementing methods, for example, to seal voids in pipe strings or cement sheaths, to seal highly permeable formatio zones or fractures, to place a cement plug, and the like.
- void refers to any type of space, including fractures, holes, cracks, channels, spaces, and the like.

- the resin-based sealant composition may be allowed to harden in the subterranean formation for a number of purposes including, without limitation: to isolate the subterranean, formation from a portion, of the well bore; to support a conduit in the well bore; to plug a void in the conduit; plug a void in a cement, sheath disposed in an annukis of the well bore; to plug a perforation; to plug void (e.g., micro-annuius) between the cement sheath and the conduit; to prevent the loss of aqueous or nonaqueous drilling fluids into loss circulation zones such, as a void, vugolar zone, or fracture; to plug a well for abandonment purposes; to form a temporary plug to divert treatment fluids; as a chemical packer to be used as a fluid in front of cement slurry in cementing operations; or to sea!
- the resin-based sealant composition may withstand substantial amounts of pressure, e.g., the hydrostatic pressure of a drilling fluid or cement slurry, without being dislodged or extruded.
- the resin-based sealant composition may set into a flexible, resilient and tough material, which may prevent further fluid losses when circulation is resumed.
- the resin-based sealant composition may also form a .non-flowing, intact mass inside the loss-circulation zone. This mass plugs the zone and inhibits loss of subsequently pumped drilling fluid, which allows for further drilling.
- embodiments of the resin- based sealant composition may be introduced into a well-bore annulus such as a space between a wall of a well bore and conduit (e.g., pipe strings, liners) located in the well bore or between the conduit and a larger conduit in the well bore.
- the resin-based sealant composition may be allowed to harden to form an annular sheath of the hardened composition in the well-bore annulus.
- the hardened composition formed by the resin-based sealant composition may form a barrier, preventing the migration of fluids in the wet! bore.
- the hardened composition also may, .for example, support, the condui in the well bore and/or form a bond between the well-bore wall and the conduit.
- the conduit may also be cemented into a well-bore annulus by utilizing what is known as a reverse-cementing method.
- the reverse-cementing method comprises displacing the resin-based sealant composition into the annulus between the conduit and the annulus between an existing string, or an open hole section of the wellbore, As the resin-based sealant composition is pumped down the annular space, drilling fluids ahead of the resin-based sealant composition are displaced around the lower ends of the conduit and up the inner diameter of the conduit and out at the surface. The fluids ahead of the resin-based sealant composition may also be displaced upwardly through a work string that has been run into the inner diameter of the conduit and sealed off at its lower end.
- the work string has a smaller inner diameter, fluid velocities hi the work string will be higher and will more efficiently transfer the cuttings washed out of the annulus during placement of the resin-based sealant composition.
- a small amount of resin-based sealant composition will be pumped into the conduit and the work string.
- the work string may be pulled out of its seal receptacle and excess resin-based sealant composition that has entered the work string can be reverse-circulated out the lower end of the work strin3 ⁇ 4 to the surface.
- a resin-based sealant composition may be used, for example, in squeeze•cementing operations or in the placement of cement plugs.
- the resin-based sealant composition may be placed in a well bore to plug voids, such as holes or cracks in the pipe strings; holes, cracks, spaces, or channels in the sheath; and very small spaces (commonl referred to as "micro-annuit between the sheath and the exterior surface of the pipe or well-bore wail
- compositions and methods are described in terms of “comprising,” “containing,” or “including” various components or steps, the compositions and methods can also “consist essentially of or “consist of the various components and steps.
- indefinite articles “a” or “an,” as used in the claims, are defined herein to mean one or more than one of the element that it introduces.
- ranges from any lower limit may be combined with any upper limit to recite a range not explicitly recited, as well as. ranges from any lower limit may be combined with any other lower limit to recite a range not explicitly recited, in the same way, ranges from any upper limit ma be combined with any other upper limit to recite a range not explicitly recited.
- any number and any included range falling within the range are specifically disclosed, in particular, every range of values (of the form, "from about a to about b,” or, equivalent!)'', “from approximatel a to b,” or, equivalently, “from approximately a-b") disclosed herein is to be understood to set forth every number and range encompassed within the broader range of values even if not explicitly recited.
