Acid foam fracturing

Acid foam fracturing. Volz, Herbert A. (Phillips Petroleum Co., USA). U.S. US 4044833 30 Aug 1977, 5 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: E21B043-26. NCL: 166307000. APPLICATION: US 76-694114 8 Jun 1976. DOCUMENT TYPE: Patent CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 43, 46, 49 Foam, obtained by aeration of an acid soln. contg. CM-cellulose propping agent and a surfactant and used for fracturing petroleum and natural gas formations, was described. Thus, an aq. soln. contg. 12.5 wt.% HCl and 0.5 wt.% surfactant Igepal DM 970 [9014-93-1] was aerated with N for 24 h to give a foam having a foam collar height in Ross-Miles app. after 0 and 5 min 6.0 and 4.5 cm, resp.

Emulsion suspensions and process for adding them to system

Emulsion suspensions and process for adding them to system. Lissant, Kenneth J. (Petrolite Corp., USA). U.S. US 3974116 10 Aug 1976, 9 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C08J003-12. NCL: 260029200UA. APPLICATION: US 74-452846 20 Mar 1974. DOCUMENT TYPE: Patent CA Section: 35 (Synthetic High Polymers) Section cross-reference(s): 60 Stable suspensions of solid particulate sol. polymer in a high internal phase ratio emulsion contain an emulsifying agent, a liq. oil and liq. non-oily phase (contg. a hygroscopic salt), neither of which as present in emulsions substantially dissolve, swell, or react with the polymer normally sol. in .In this article, certain chemicals are used. Some of their cas registry numbers are 64-17-5 and 9003-01-4 gtoreq.1 of the phases; the non-oily phase has a cohesive energy d. number >.apprx.10. The emulsion suspensions are stable to settling and deterioration, and can be added to systems with much greater facility than when adding the solid alone. Thus, CaCl2 dihydrate 100, water 60, denatured EtOH [64-17-5] 40 g were mixed to dissolve all solids (soln. A). Kerosene (16 ml) and 4 ml ethoxylated dinonylphenol [9014-93-1] were stirred, along with addn. of 50 ml soln. A to give a translucent water-in-oil emulsion. Granular acrylic acid polymer [9003-01-4] (41 g) was added slowly with stirring to give a thick suspension. The suspensions may be used to add water-sol. polymers to aq. systems or oil-sol. polymers to non-aq. systems, and for clarification of water contg. suspended matter. .
