FIELD: drilling of soil or rock.
SUBSTANCE: group of inventions relates to methods applicable to a wellbore passing through a subterranean formation. Deflecting composition comprises a treatment fluid containing non-bridged fibers and particles containing degradable material. In this case, the fibers are crimped staple fibers that contain from 1 to 10 turns/cm of length, the bending angle is from 45 to 160 degrees, the average fiber length in the stretched state is from 4 to 15 mm, the average diameter is from 8 to 40 microns, or a combination of these parameters.
EFFECT: technical result is to increase the efficiency of processing the underground formation.
