Abstract: A hydraulic fracturing method for recovering oil from a low-temperature subterranean oil formation is disclosed. Before, during, or after inducing hydraulic fracturing within the formation, a particulate, degradable polyester diverting agent is introduced into the formation in an amount effective to improve oil production from the formation. The diverting agent is allowed to degrade, and oil is recovered. The diverting agent has a melting point greater than the average temperature of the formation and is selected from: (i) ethylene glycol succinates; (ii) acid-terminated ethylene glycol succinates; (iii) acid-terminated polyglycolic acids; (iv) acid-terminated polylactic acids; and (v) mixtures of any of (i) through (iv) with a half acid ester.

Abstract: Non-aqueous solder flux compositions are disclosed. In some aspects, the compositions comprise: (a) an alkylbenzene sulfonic acid or an acidic phosphate ester; and (b) an alkanolamide, an ethoxylated alkanolamide, an alkanolamine, or an ethoxylated amine. Methods of making solder flux compositions and methods of using the compositions as components of tacky solder fluxes are described. The solder flux compositions have excellent wettability, oxide removal capability, and rheological characteristics for high-speed, pick-and-place manufacturing processes and can be made from a simple combination of two components, thereby avoiding the need for solvents, polymeric thickeners, and other components of traditional tacky solder fluxes.
