Abstract

Methods of continuously forming and suspending consolidatable resin composition coated particulate material in a gelled aqueous carrier liquid and transporting the coated particulate material by way of the gelled aqueous carrier liquid to a zone in which the sand is consolidated. In accordance with the methods, substantially continuous streams of a gelled aqueous carrier liquid, uncoated particulate material, a resin composition which will subsequently harden and a surface active agent are admixed whereby the particulate material is continuously coated with the resin composition and suspended in the gelled aqueous carrier liquid.
