Next, the cells are thawed using a controlled, relatively slow warming rate. Each connector assembly includes a fixed component and a rotatable component. The well treatment fluid can include fibers to provide reinforcement and consolidation of the proppant and, additionally or alternatively, to inhibit settling of the proppant in the treatment fluid.
