CONTROL OF PARTICULATE FLOWBACK IN SUBTERRANEAN WELLS

摘要

The addition of fibrous materials in intimate mixture with particulates for fracturing and gravel packing decreases or eliminates the flowback of proppant and/or formation fines while stabilizing the sand pack and lowering the demand for high polymer loadings in the placement fluids. Preferred fibers include glass, aramide, nylon and other natural and, synthetic organic and inorganic fibers and metal filaments.
