FIELD: soil or rock drilling.
SUBSTANCE: disclosed is a method of treating an underground formation using a suspension containing a portion of material susceptible to shrinkage. This processing method may include processing to perform deviation during the formation fracturing operation. Material subjected to shrinkage can be made with possibility of shrinkage at temperature change. Suspension may be used for clogging perforation channel or crack in formation.
EFFECT: disclosed is a method of treating an underground formation.
