Abstract

NON-EXPANDABLE LINER SUSPENSION. Methods and apparatus for positioning a non-expandable liner suspension in a wellbore. A liner is coupled to the liner suspension, wherein the liner suspension comprises: a conduit body; and a reactive metal sealing element disposed in the conduit body, wherein the reactive metal sealing element comprises a reactive metal having a first volume. An example method includes contacting the reactive metal with a fluid that reacts with the reactive metal to produce a reaction product having a second volume larger than the first volume; and contacting a surface adjacent to the reactive metal sealing element with the reaction product to form a seal against the surface and to anchor the liner suspension to the surface, wherein anchoring the liner suspension to the surface suspends the liner in the wellbore.

Description

TECHNICAL FIELD [001] This disclosure relates to the use of a non-expandable liner hanger and, more particularly, to the use of a non-expandable liner hanger having reactive metal sealing elements for sealing and anchoring the non-expandable liner hanger in wellbore applications. FUNDAMENTALS [002] In some well drilling operations, a liner may be suspended from a casing string or cement layer laid with a liner hanger. The liner hanger anchors inside the casing string or cement layer and suspends the liner below the casing string or cement layer. The suspended liner and liner hanger do not extend to the surface as a casing string or cement layer might. A liner hanger forms a seal with the casing string or cement layer to prevent fluid flow from outside the suspended liner. Fluid flow can be directed through the casing instead. [003] Sealing elements can be used for a variety of wellbore applications, including forming annular seals within and around liner hangers and anchoring liner hangers to suspend the liner. The annular seal can restrict all or a portion of fluid and/or pressure communication at the seal interface. These sealing elements can seal and anchor liner hangers to the adjacent surface, such as the casing string or the laid cement layer. Some types of sealing elements comprise intumescible materials that can swell upon contact with a specific swelling-inducing fluid. [004] Many of the above-mentioned swelling materials comprise elastomers. Elastomers, such as rubber, swell when in contact with a swelling-inducing fluid. The swelling-inducing fluid can diffuse into the elastomer where a portion of the fluid can be retained within the elastomer's internal structure. Swelling materials, such as elastomers, may be limited to use in specific wellbore environments (e.g., those without high salinity and/or high temperatures). The present disclosure provides improved apparatus and methods for sealing around and anchoring liner hangers in wellbore applications.
