Abstract
Fibers comprising a first thermoplastic composition having a softening temperature up to 120° C and a curable resin. Also disclosed are compositions comprising a plurality of fibers, with some of the fibers comprising a first thermoplastic composition having a softening temperature up to 120° C and some of the fibers comprising a curable resin. The fibers have an aspect ratio of at least 2:1 and a maximum cross-sectional dimension up to 60 micrometers. Fluid compositions containing the fibers and methods of contacting a subterranean formation using the fibers are also disclosed.
Claims20
A fiber comprising:
- a first thermoplastic composition having a softening temperature up to 120° C., and
- a curable resin,
- the first thermoplastic composition and the curable resin each forming a portion of the fiber, wherein the fiber has an aspect ratio of at least 2:1, and wherein the fiber has a maximum cross-sectional dimension up to 60 micrometers.
A composition comprising a plurality of fibers comprising:
- thermoplastic fibers comprising a first thermoplastic composition having a softening temperature up to 120° C., wherein each thermoplastic fiber independently has an aspect ratio of at least 2:1 and a maximum cross-sectional dimension up to 60 micrometers;
- and
- curable fibers comprising a curable resin, wherein each curable fiber independently has an aspect ratio of at least 2:1 and a maximum cross-sectional dimension up to 60 micrometers,
- the thermoplastic fibers and the curable fibers each forming a portion of the plurality of fibers.
