ABSTRACT:
The present invention involves methods of preparing coated particulates and using such coated particulates in subterranean applications such as production enhancement and sand control. One embodiment of the present invention provides a method of preparing coated particulates comprising the steps of coating particulates with a resin or a tackifying agent to create pre-coated particulates; and, covering the pre-coated particulates with a partitioning agent to create coated particulates. Another embodiment of the present invention provides a method of treating a subterranean formation comprising the steps of providing coated particulates made by a method comprising the steps of substantially coating particulates with a resin or a tackifying agent to create pre-coated particulates; and, substantially covering the pre-coated particulates with a partitioning agent to create coated particulates; substantially slurrying the coated particulates in a servicing fluid to create a coated particulate slurry; and, placing the coated particulate slurry into the subterranean formation.
