Abstract
The invention relates to modified reinforcement fibers for use in a variety of applications. The modification includes crimping linear or straight reinforcement fibers to create a deformed or different shaped reinforcement fiber. Examples of the shaped fibers resulting from crimping include w-shaped, s-shaped, z-shaped and wedge-shaped.
Claims6
A modified reinforcement fiber-containing drilling liquid, comprising:
- a drilling liquid;
- and
- a reinforcement fiber component in a form selected from individual fibers, a clip of fibers and a bundle of fibers, at least a portion of the reinforcement fiber component comprises a plurality of modified reinforcement fibers each having a length from about 3 to 25 millimeters and a deformation formed in the length, wherein the deformation includes at least one crimp,
- wherein, the reinforcement fiber component and the drilling liquid form a blend or mixture, and
- wherein, the modified reinforcement fiber-containing drilling liquid is effective to increase suspension and debris removal from a wellbore as compared to a drilling liquid absent of the plurality of modified reinforcement fibers.
