Abstract: A method of treating a formation includes preparing an aqueous solution having HCl in an amount between greater than 15% and 45.7% by weight, inclusive. The prepared aqueous solution includes a fixing agent (FA) present in a molar ratio of FA:HCl between 0.15 and 2.5 inclusive, where the FA is urea and/or a urea derivative, and further includes water present in an amount sufficient to dissolve the HCl and the FA. The aqueous solution includes substantially no polysaccharides.The method further includes providing an oilfield treatment fluid including the aqueous solution to a high pressure pump operating the high pressure pump to treat a wellbore and/or the formation fluidly coupled to the wellbore.

Abstract: A well stimulation modeling method and simulation model for modeling a stimulation treatment involving a chemical reaction between a treatment fluid and a porous medium, such as acid treatment of a carbonate formation. In a wormhole initiation stage or mode, the medium of the cells having a solid saturation above a respective critical solid saturation is comprised of matrix material behaving as a single permeability, single porosity system; and in a wormhole growth stage or mode, the cells having a solid saturation equal to or less than the respective critical sold saturation comprise two different interconnected media, the matrix material and a wormhole material, defined to include wormhole-forming material as well as mature wormholes, having fluid mobility as a function of the solid saturation.

Abstract: Aqueous compositions contain hydrochloric acid at a concentration between 8 wt % and 28 wt % inclusive. The amino acid; hydrochloric acid mole ratio may be between 0.2 and 1.5. Sufficient water is present to dissolve the hydrochloric acid and the amino acid. Such compositions have utility as retarders for acid compositions employed in the stimulation of subterranean formations. Slowing the reaction between the acid and formation helps maximize formation permeability and productivity.
