Abstract:
Proppants are used in oil and gas extraction, particularly in fracking operations. The invention relates to resin coated proppants. The coatings on proppants have antimicrobial materials incorporated within these coatings. The antimicrobially active agents are incorporated in a concentration less than 70% by weight of the coatings or the active agent from these coatings can be released from these coatings in the environment of the proppants.

Claim (Index 19):
A method of forming oil-field proppant particles coated with a polymeric coating containing at least one antimicrobial material, the method comprising:\n a) mixing said antimicrobial material with a polymeric coating formulation to form a polymeric coating mixture, wherein the antimicrobial material is greater than 20 wt % and less than 70 wt. % as compared to the weight of said polymeric coating; b) coating said polymeric coating mixture onto the oil-field proppant particles; and c) at least one of drying, partially curing and curing the polymeric coating mixture, such that the said oil-field proppant particles are coated with the polymeric coating that releases the antimicrobial material or a component of the antimicrobial material with antimicrobial properties under conditions present in an oil well.
