摘要： Polyesters having both α,β-unsaturated groups and moieties containing activated methylene or methine groups, such as those of beta-ketoester and malonate, are curable in the presence of a base catalysts to form crosslinked networks. Formulations based on such polyesters are suitable for use in coatings and cure at temperatures less than 230° C. without the use of isocyanates.

摘要： A fiber delivery system capable of providing cut fiber segments for use in treating an oil and/or gas well. The fiber delivery system can utilize bales of a continuous filamentary tow that are transported to the well site from a remote manufacturing location. At the well site, a multifilament strand can be pulled off the bale, opened, and cut to provide cut fiber segments. The cut fiber segments can be mixed with other well treatment components to create a well treatment medium that is introduced into the well as part of a drilling, stimulation, or cementing process.

摘要： Degradable particulate materials are provided that may be utilized in various wellbore treatment fluids, such as hydraulic fracturing fluids. In particular, the degradable particulate materials can be formed from a cellulosic polymer, a polyester polymer, a polyvinyl alcohol, or a guar gum ester that are capable of effectively degrading at specific rates when exposed to the aqueous environments in low temperature wellbores (50° C. to 100° C.).

摘要： Suspension of proppants in hydraulic fracturing applications can be strongly affected by the cross-sectional shapes and lengths of the fibers present in the wellbore treatment compositions. For instance, it has been observed that crimped cellulose ester fibers with a trilobal cross-section and an optimized length can provide enhanced suspension of proppants in aqueous fracturing fluids. Furthermore, the present invention demonstrates that non-round cellulose ester fibers can provide superior proppant suspension properties relative to polylactic acid fibers with a round cross-section.
