Abstract
Fibers are employed to improve proppant transport in low viscosity treatment fluids. The treatment fluids employ fibers to inhibit proppant settling without an unacceptable bridging tendency. The fibers are preferably crimped staple fibers having 1-10 crimps/cm of fiber length, a crimp angle between 45 and 160 degrees and a mean diameter between 8 and 40 microns.
