Composition and method for reducing the surface tension of aqueous fluids: Composition and method for reducing the surface tension of aqueous fluids. Thompson, James L. (Dow Chemical Co., USA). U.S. US 4028257 7 Jun 1977, 3 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: E21B043-27. NCL: 252008550C. APPLICATION: US 74-527577 27 Nov 1974. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 46, 37 The surface tension of aq. fluids used in petroleum and natural gas recovery from underground formations is reduced by the addn. of [C8F17SO2NHC3H6NMe3]+- (I; x = halide) and an adduct of trimethyl-1-heptanol and 7 mol ethylene oxide. Thus, the surface tension of a brine contg. 8 wt.% NaCl and 2.5 wt.% CaCl2 was reduced from 74.3 to 22.0 dyne/cm when 2 gal of a mixt. contg. H2O 29.6, iso-PrOH 3185, the adduct of trimethyl-1-heptanol and 7 mol ethylene oxide 1535, and I (X = I) [1652-63-7] 40 wt. parts was added to 1000 gal of the brine.

U.S. US 4018689 19 Apr 1977, 3 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: E21B043-26. NCL: 252008550C. APPLICATION: US 74-527576 27 Nov 1974. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 46, 66 The surface tension of aq. fluids used in the treating of subterranean deposits to stimulate petroleum recovery (e.g., acidizing and fracturing) is reduced by introducing an aq. compn. contg. C8F17SO2NHC3H6N+Me3 I- (A) [1652-63-7], a surfactant (B) contg. polyethylene glycol monostearate [9004-99-3] 57, Na bis(2-ethylhexyl) sulfosuccinate [577-11-7] 19.2, bis(2-ethylhexyl) maleate [142-16-5] 3, isooctyl alc. [26952-21-6] 10.1, iso-PrOH [67-63-0] 4.5, and H2O 6.2 wt.%, and a 3rd surfactant selected from an adduct of a C10-12 alc. with 5 mol ethylene oxide, an adduct of trimethyl-1-heptanol with 7 mol ethylene oxide, and mixts. of these adducts. Thus, the surface tension of 1000 gal brine (8 wt.% NaCl and 2.5 wt.% CaCl2) was reduced from 74.3 to 22.8 dyne/cm by introducing 2 gal of a soln. contg. H2O 2502, iso-PrOH 1967, surfactant B 2655, an adduct of trimethyl-1-heptanol with 7 mol ethylene oxide 836, and A 40 wt. parts.
