US Patent:

20130196884, Aug 1, 2013

Filed:

Feb 1, 2012

Appl. No.:

13/364156

Inventors:

Sarkis Kakadjian - The Woodlands TX, US
James Joseph Venditto - Houston TX, US
Frank Zamora - San Antonio TX, US
Ronald Joseph Powell - Humble TX, US
Joseph E. Thompson - Houston TX, US

International Classification:

C09K 8/80
B05D 1/36

US Classification:

507203, 507200, 507269, 427402

Abstract:

A method of reducing the cost and environmental impact of chemicals used in hydraulic fracturing is to use a proppant that is coated with at least two chemicals, where each of those chemicals are useful in treating a well. By coating at least two chemicals onto the proppant the amounts of chemicals required to treat a well are reduced by delivering the chemicals to only the areas that require treatment. Additionally mixing issues are avoided as only a single proppant or substrate is used in the well.

International Classification:

C09K 8/00
C09K 8/52

US Classification:

507200

Abstract:

A method of reducing the cost and environmental impact of chemicals used in hydraulic fracturing is to use multiple chemicals that are pre-mixed and then formed into a single solid blended mixture. By forming at least two chemicals into a single solid mixture, the complexity involved in transporting multiple solid or liquid chemicals is avoided. If the solid chemicals were merely premixed they would tend to segregate during shipping, handling, and storage altering the concentration of the chemical mix as it is pumped downhole. Simply having less equipment on the wellsite increases the accuracy of the well treating process and decreases the likelihood of a time consuming and thus costly delay due to equipment failure.

Ronald Dean Powell - McKinney TX, US

International Classification:

H01L 21/02
H01L 21/027

Abstract:

A method, which forms an air-bubble-free thin film with a high-viscosity fluid resin, initially dispenses the fluid resin on an outer region of a semiconductor wafer while the semiconductor wafer is spinning, and then dispenses the fluid resin onto the center of the semiconductor wafer after the semiconductor wafer has stopped spinning.
