treating the subterranean formation the material may comprise thermoplastic material capable of softening upon heating or softening at the temperature of the subterranean formation whereby it may adhere to the particulates with which it is introduced examples of suitable materials include polyolefins including polyethylene polypropylene polybutylene polymers and fluoropolymers and copolymers polyimides polyurethanes polysulfones polycarbonates and cellulose derivatives the material also may comprise glass ceramic carbon natural or synthetic polymers or metal filaments and the like the adhesive coated material may be utilized in substantially any physical form such as for example ground material ribbons flakes fibers and the like the adhesive coated material may comprise ground material having an average particle size of from about 10 to about 150 mesh on the u s sieve series when the material is in the form of a ribbon it may be from about 2 5 to about 250 microns thick from about 0 4 to about 6 5 millimeters wide and from about 5 to in excess of from about 50 millimeters in length when in flake form the adhesive coated material may have a thickness of from about 2 5 to about 250 microns and may have either a regular of irregular shape and will have a surface area in the range of from about 2 to about 325 square millimeters when in fiber form it may have an average or effective diameter of from about 2 to about 200 microns and a length of at least about 2 millimeters the length of the fibers is limited only by the practical applications of handling pumping and the like the current practical limit to the length is about 100 millimeters the quantity.
