Proppant mixtures

The invention relates to a propped, fractured, subterranean field with (a) a first proppant and (b) a second proppant that exhibits a relatively higher average crush strength and/or an ability to form a particle to particle bonded structure than the first proppant. Preferably, the first proppant is uncoated sand and the second proppant is resin-coated sand. ... Preferred Technology Llc

Durable coatings and uses thereof

Coatings and compositions are provided for coating particulates that can be used as, for example, as proppants. The proppants can be used, for example, to extract oil and gas from subterranean formations.. ... Preferred Technology Llc

Hydrophobic coating of particulates for enhanced well productivity

Compositions and methods for coated or uncoated particulates, such as proppants, are provided that can, among other things, provide a hydrophobic surface that can enhance well productivity and other compositions and methods are disclosed.. . ... Preferred Technology Llc

Compositions and methods of using hydrophobic coating of particulates and cross-linked fracturing fluids for enhanced well productivity

Compositions and methods for extracting oil and gas from a fractured subterranean formation are provided.. . ... Preferred Technology Llc

Hydrophobic coating of particulates for enhanced well productivity

Compositions and methods for coated or uncoated particulates, such as proppants, are provided that can, among other things, provide a hydrophobic surface that can enhance well productivity and other compositions and methods are disclosed.. . ... Preferred Technology Llc

Dual function proppants

Proppants for use in fractured or gravel packed/frac packed oil and gas wells are provided with a contaminant removal component to remove one or more of the contaminants found in subterranean water/hydrocarbon from a production well. The water/hydrocarbon cleaning proppant solids may be used as discrete particles in a proppant formulation, as a coating on proppant solids in pores of a porous proppant solid or as part of the proppant's internal structure. ... Preferred Technology Llc

Proppant with polyurea-type coating

Proppants for hydraulic fracturing of oil and gas wells are coated with a polyurea-type coating. In a preferred embodiment, the polyurea-type coating is formed by contacting a polymeric isocyanate with an amount of water a blowing catalyst at a rate and quantity sufficient to generate a reactive amine in situ on the outer surface of the proppant which thereby reacts with unconverted polymeric isocyanate to form a thin polyurea-type surface coating that is substantially solid and lacks foam or substantial porosity. ...
