Abstract: Described is a drilling fluid composition with enhanced hole cleaning properties and a method of its use. Following an indication of sticking of a drill pipe during a drilling operation, a drilling fluid composition, including a first exothermic reactant, is injected into a subterranean formation. Then, a drilling fluid composition, including a second exothermic reactant, is injected into the subterranean formation. An exothermic reaction is allowed to occur between the first exothermic reactant and the second exothermic reactant within the subterranean formation.

Abstract: A process for preparing bi-modal water emulsions is disclosed comprising: I) forming a mixture comprising; A) 100 parts by weight of a hydrophobic oil, B) 1 to 1000 part by weight of a water continuous emulsion having at least one surfactant, II) admixing additional quantities of the water continuous emulsion and/or water to the mixture from step I) to form a bi-modal emulsion.

Abstract: An effective and non-toxic oil spill dispersant combines a predominately oil-soluble surfactant (eg., polyethylene glycol mono-oleate) with a predominately water-soluble surfactant (eg., cocoamide) and a co-solvent for coupling a mixture of the predominately oil-soluble surfactant and the oil spill, with the predominately water-soluble surfactant. Water is included in the combination to help advance the interaction between the predominately oil-soluble surfactant and the predominately water-soluble surfactant as well as the co-solvent. The water component also helps reduce the viscosity of the dispersant to allow it to be pumped under pressure.
