Abstract: A proppant may include particles including a sintered ceramic composition, wherein the particles have a particle size distribution such that less than 25 wt. % of the particles have a particle size less than 100 mesh, and wherein the particles have a particle size distribution such that less than 1 wt % of the particles have a particle size greater than 60 mesh. The particles may have a sphericity ranging from 0.4 to 0.9. A proppant may include particles including a sintered ceramic composition, wherein the proppant has a conductivity of at least 1.5 times the conductivity of 100 mesh sand. A method of treating a subterranean area around a well bore may include providing a fracturing fluid including such proppants, and injecting the fracturing fluid into the subterranean area around the well bore.

Abstract: Disclosed herein is a method of making a rigid polymer product, such as an impact resistant halogen containing polymer, comprising adding to a halogen containing resin at least one mineral filler comprising coated calcium carbonate having a hydrophobic coating derived from at least one aliphatic carboxylic acid comprising at least 10 carbon atoms in the main chain, and no more than 0.01% by weight of agglomerates or particles having a particle size greater than 44 ?m. Further disclosed herein are rigid polymer products comprising this coated calcium carbonate for use in applications that benefit from impact resistant properties, such as vinyl siding and PVC pipes and fittings.
