SURFACTANT SYSTEM METHOD

摘要

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.
