Title:
COMPOSITIONS, METHODS, APPARATUS, AND SYSTEMS FOR INCORPORATING BIO-DERIVED MATERIALS IN DRILLING AND HYDRAULIC FRACTURING
Document Type and Number:
WIPO Patent Application WO/2012/166561
Kind Code:
A3
Abstract:
The present invention provides compositions, methods, apparatus, and systems to minimize environmental impact, water use, and overall cost of drilling and hydraulic fracturing for crude oil and natural gas. Some variations of the invention provide a fracturing-fluid additive composition comprising a water-soluble portion of a biomass-pyrolysis liquid. In some embodiments, the fracturing-fluid additive composition is substantially biodegradable and is not toxic. Some variations provide improved proppants for oil or gas well fracturing. Other variations of this invention relate to drilling-fluid additive compositions, and methods of using these compositions. This invention can significantly improve the environmental, economic, and social sustainability associated with drilling and fracturing for production of oil and gas.
