Abstract: A method of slurrifying oil contaminated materials by introducing a microemulsion or microemulsion-forming surfactant(s) to the material and subjecting the mixture to suitable shear or mixing forces to suitably blend such mixtures. The method may be applied directly to wastes such as waste drill mud cuttings and muds, emulsions, sludges, or soil substrates contaminated with water and/or oil drilling fluids in order to both reduce the viscosity and improve the lubricity, wetting, and flow properties of the substrate.

Abstract: A cleaning composition including which comprises a surfactant and a propionate as co-surfactant and/or co-solvent. The composition can be used, for example, to clean drilling mud containing oils.

Abstract: A compound having the general formula I wherein R comprises a hydrocarbon group including H, branched or linear alkyl chains, substituted alkyl, alkenyl, aryl, alkaryl or cyclic groups; R1 is any of C, N, P, B, S, or SiO4 or any subgroups thereof; R2 is any of a covalent bond, O, CH2, (CH2)n where n may be 1-10 carbons long; R3 is any of a covalent bond, O, CH2, (CH2)n where n may be 1-10 carbons long; R2 and R3 may be the same or different; R4 is any of O, H, OH, CH3, (CH2)nCH3, (CH2)nOH, (CH2)nOX or any combinations thereof where n is from 1 to 10. OX is a water soluble group; chains a and b are in the range 1-10 carbons each; and the alkoxy chains c and d are in the range 1-20 units each.

Abstract: The invention relates to the formulation and application of water based predominantly pH neutral microemulsions and microemulsion forming surfactant systems essentially comprising a surfactant or surfactant˜end, lactates)—esters) of lactic acid—and water/brine and optionally solvent. Uniquely the formulations are acid and caustic free and also do not make use of alcohol, glycol and glycol ether components in the systems as co surfactant, co-solvent or mutual solvent. In particular the invention relates to the methods and the application of this microemulsion technology for use in industrial hard surface cleaning applications especially the inks and printing industries and the oil and gas industry. In addition the formulations can be used in the production of microemulsion based drilling muds (which may or may not be Oil Based Muds—OBMs) and they may be used to enhance the drill cuttings slurrification processes for re-injection purposes or for facilitated cuttings transport.
