Abstract
Improved methods of treating subterranean formations using solid particles and other larger solid materials are provided. The methods are basically comprised of the steps of introducing a carrier fluid containing suspended solid particles which have been coated with a non-hardening tackifying agent into a subterranean formation, mixing a solid material of larger size with the tackifying compound coated solid particles whereby the solid particles stick to the larger solid material and the solid particles and larger solid material are uniformly suspended in the carrier fluid and depositing the larger solid material and the tackifying compound coated smaller solid particles in the subterranean formation.

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