may be guargum is much better proppant than CRR's resin coated proppants thats why there are so many shorts on crr
guar is a viscosifier not a proppant
AAny news on potential big orders backlog for the CARBOECONOPROP, perhaps Oxy and Apache starting up use in Egypt and China shales!
Guar gum is a viscosifier, not a proppant. You use the viscosifier to prevent the proppant from settling out in the frac fluid.
