ABSTRACT:
Low density fibrous materials such as carbon fibers are readily added and dispersed into a liquid such as a fracturing fluid liquid by injecting the fibers into the liquid adjacent to the liquid-gas interface at the surface of the liquid. The fibrous materials are preferably compacted to a uniform bulk density in a container in which all the gas in the compacted fibers has been displaced by a liquid. A crimped cartridge having a piston to discharge the compacted fibrous material into the liquid is preferred.
