Depending on specific conditions, such effects may lead to collapse of the borehole or a reduction in the fracture-initiation pressure. WebIn an inclined configuration, the addition of fibers to hole-cleaning sweeps substantially improves cuttings removal, but only when the pipe is rotated. When the annulus is horizontal or the pipe is not rotated, addition of fiber has only a small effect on cuttings bed removal [ 29 ].
