Patent

CA 2576075

An oilfield treatment method is given that uses fluids that contain surfactants used as foamers and/or viscosifiers such that the fluids pass the Alberta Energy and Utilities Board Directive 27 requirements for low toxicity to certain bioluminescent bacteria. Such fluids may be used in oilfield treatments, for example drilling and stimulation, near fresh water aquifers. The surfactants are certain non-ionic surfactants that are not aromatic, or certain amphoteric surfactants (that can be neutral), or certain zwitterionic surfactants, (in which both positive and negative charges are present in a single molecule so that the whole molecule is neutral).

On présente un procédé de traitement de champ pétrolifère qui utilise des fluides contenant des surfactants utilisés comme agents moussants et/ou améliorants de viscosité, de sorte que les fluides soient conformes aux exigences de la Directive 27 de l'Alberta Energy and Utilities Board sur la faible toxicité pour certaines des bactéries bioluminescentes. Ces fluides peuvent être utilisés dans les traitements de champs pétrolifères, par exemple à des fins de stimulation et de forage, à proximité des aquifères d'eau fraîche. Les surfactants sont certains surfactions non ioniques qui ne sont pas aromatiques, ou certains surfactants amphotères (pouvant être neutres), ou certains surfactants zwittérioniques (dans lesquels les deux charges positives et négatives sont présentes dans une molécule unique pour que la molécule entière soit neutre).
