Abstract:
A method of treating a subterranean formation comprising the steps of:(a) introducing a carrier fluid containing suspended solid particles which have been coated with a non-hardening tackifying agent into said subterranean formation; (b) mixing a deformable particulate of larger size than said solid particles with said carrier fluid and said tackifying compound coated solid particles suspended therein whereby said smaller solid particles stick to said larger deformable particulate and said larger deformable particulate is suspended in said carrier fluid along with said smaller solid particles; and (c) depositing said larger deformable particulate and said tackifying compound coated smaller solid particles stuck thereto in said subterranean formation so that upon flowing back fluid from said formation said smaller solid particles and said larger deformable particulate do not flow-back.
