Abstract: A casing string is augmented with one or more variable flow resistance devices or “vibrating tools” to facilitate advancement of the casing and distribution of the cement in the annulus once the casing is properly positioned. The method includes vibrating the casing string while advancing the casing down the wellbore or while the cement is pumped into the annulus, or both. After the cementing operation is completed, the devices may be drilled out to open the casing string for further operations. The casing string assembly may include a vibrating tool at the end in place of a conventional float shoe or float collar. Multiple vibrating tools can be employed in the casing string, and they may be combined with conventional float shoes and collars. Additionally, vibrating tools in the form of plugs can be pumped down and landed inside the casing string.

Abstract: The oxidation of isobutyraldehyde produces isobutyric acid and byproducts, such as isopropyl formate. A process of reducing the isopropyl formate byproduct and other byproducts in the oxidation of isobutyraldehyde is described. The process uses a carbonyl compound, such as acetone, to reduce byproduct levels in the resulting product. Process for use of static mixers in oxidation reactions of aldehydes are also provided.

Abstract: There is provided is a method for making a higher purity alcohol comprising: a) contacting an impure alcohol composition comprising: (i) an alcohol compound; and (ii) from about 50 ppm to about 5 weight percent, based on the weight of the impure alcohol composition, of at least one hydrogenable contaminant having an unsaturated bond, with hydrogen in a hydrogenation reactor and in the presence of a hydrogenation catalyst to produce a reaction mixture comprising the alcohol compound and a hydrogenated contaminant product wherein at least 10 mole % of the at least one hydrogenable contaminant in the reaction mixture is converted; and b) separating the alcohol compound from at least a portion of the reaction mixture to produce an enriched alcohol composition having a lower concentration of the hydrogenated contaminant product. There is also provided an alcohol composition having less than about 500 ppm of at least one hydrogenable contaminant.

Abstract: A suspension system having a stabilizer bar assembly with a stabilizer bar structure, an intermediate bushing and a resilient bushing. The stabilizer bar structure includes a center section to which the intermediate bushing is coupled. The resilient bushing is mounted on the intermediate bushing. The intermediate bushing limits relative axial movement of the resilient bushing in along the center section in a first direction and a second direction opposite the first direction. A method for forming a stabilizer bar assembly is also provided.
