Abstract:
Proppants coated with a curable resin containing 2.5-12% of a hydrophobic fumed silica having a BET surface area of 20 to 600 m 2 /g exhibit high resistance to cracking and flaking, and are useful in fracking operations in subterranean formations for recovery of oil and/or gas.

Claim (Index 8):
A method for producing coated proppants, comprising:\n applying a reactive resin composition in flowable form, the composition optionally containing a hardener (C), and optionally containing additive(s) (D) to the proppant; and then hardening at least part of the reactive resin thus applied, wherein the reactive resin composition comprises\n (A) 88-97.5% by weight of at least one reactive resin; and \n (B) 2.5-12% by weight of at least one hydrophobically modified fumed silica having a BET surface area measured in accordance with DIN ISO 9277/DIN 66132, of between 20 and 600 m 2 /g, and having a carbon content measured in accordance with DIN EN ISO 3262-20, of 0-15% by weight.
