摘要： The present invention relates to a water-based subterranean treatment fluid, comprising: a) a continuous aqueous phase; b) an internal oil phase; c) from 0.1 to 15 g/100 ml, based on the total fluid volume, of an emulsifying composition comprising a first surfactant having a HLB from 10 to 20 and a second surfactant obtained by reacting a saturated or unsaturated aliphatic monocarboxylic acid, ethylene oxide and a hydroxyalkylamine. The invention further relates to a method for treating a subterranean formation comprising providing said water-based subterranean treatment fluid.

摘要： The formation of hydrocarbon hydrates can be inhibited or mitigated by contacting a a mixture comprising water and hydrate-forming guest molecules under gas hydrate forming conditions with a quaternary ammonium hydroxide QOH or a quaternary ammonium compound QA, in which A is not a halogen atom. The QOH or QA may be prepared reacting a quaternary ammonium halide QX with a metal hydroxide M(OH)x, or with a metal salt MA, in an alcohol solvent to form a quaternary ammonium hydroxide QOH, or a quaternary ammonium compound of formula QA, and metal halide MX. Optionally, the quaternary ammonium hydroxide QOH may be reacted with an organic or inorganic acid AH which is different from a hydrogen halide to form the quaternary ammonium compound QA. The metal halide MX may be removed by phase separation after addition of water or of a water/solvent mixture, or by filtration.
