Preparing and using and composition for acidizing subterranean formations. Dill, Walter R. (Halliburton Co., USA). U.S. US 4466893 A 21 Aug 1984, 5 pp.In this experiment, several chemicals are used like 24926-15-6 Cont.-in-part of U.S. Ser. No. 225,177, abandoned. (English). (United States of America). CODEN: USXXAM. CLASS: IC: E21B043-27. NCL: 252008550C. APPLICATION: US 82-369389 19 Apr 1982. PRIORITY: US 81-225177 15 Jan 1981. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Compns. for petroleum-well acidization are prepd. by mixing 100 mL of 22-35 wt.% HCl with 40-67.5 g urea to obtain compns. equiv. to 15-23.6 wt.% HCl; these compns. are then gelled with 80-150 lb/1000 gel hydroxypropyl guar gum [39421-75-5], carboxymethyl hydroxyethyl guar gum [85411-07-0], PEG [25322-68-3], or guar gum [9000-30-0]. Karaya gum [9000-36-6], tragacanth gum [9000-65-1], ghatti gum [9000-28-6], acacia gum [9000-01-5], konjak gum [37220-17-0], shiraz gum [9000-65-1], locust gum [9000-40-2], psyllium gum [8063-16-9], tamarind gum [39386-78-2], tara gum [39300-88-4], carrageenin [9000-07-1], kauri gum [77465-88-4], and hydroxyethyl guar gum [39465-11-7] are used. .

The effect of metal ion content on the viscosity of gum ghatti

The effect of metal ion content on the viscosity of gum ghatti. Jefferies, Martin; Pass, Geoffrey; Phillips, Glyn O.; Zakaria, Mat B. (Dep. Chem. Appl. Chem., Univ. Salford, Salford, Engl.). J. Sci. Food Agric., 29(2), 193-200 (English) 1978. CODEN: JSFAAE. ISSN: 0022-5142. DOCUMENT TYPE: Journal CA Section: 44 (Industrial Carbohydrates) Potentiometric titrn. showed that the sol. gum and insol. gel fractions of gum ghatti [9000-28-6], obtained by cold water extn., had the same acid equiv. wt. and were mainly in the salt form with <10% in the free acid form. The gel fraction was mainly a Ca salt whereas the sol. fraction contained Ca, K, Na, and Mg. Pptn. of the Ca2+ reduced the viscosity, but the original viscosity was not restored by addn. of Ca2+.
