Abstract: Oilfield treatment compositions contain water, hydrochloric acid at a concentration between 15 wt % and 45.7 wt % and a first and second fixing agent. The first fixing agent comprises urea, a urea derivative or both. The second fixing agent may be a mixture or amines and alcohols. These compositions provide corrosion inhibition when exposed to steel. The compositions may also contain an inhibitor aid.

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.

Abstract: Treatment of hydrocarbon formations using single-phase aqueous acid blends that contain lysine is described herein. The single-phase aqueous fluid includes one or more strong acid molecules and lysine in water, wherein the one or more strong acid molecules are present in a concentration range of 15 wt % to 28 wt %, based on the weight of the aqueous fluid, and lysine is present in a molar ratio of lysine to the one or more strong acid molecules that is from 1:13 to 1:40.

Abstract: Matrix acidizing treatment are designed and performed in a manner that takes into account radial acid flow into the formation. Subterranean well characteristics are determined (e.g., mineralogical and petrophysical characteristics). One of more candidate acids is selected. A linear pore volume of acid to breakthrough (PVBT) curve is generated for each candidate acid. The linear PVBT curves are modified to account for radial acid flow. The optimal acid is selected by considering wormhole development and cost. An initial acid pumping schedule is generated for the formation to be acidized, including the optimal acid, the treatment volume and the injection rate. Computer software is used to consider the subterranean well characteristics, simulate the initial acid pumping schedule and compare results with the radial PVBT curve. The initial schedule is modified until the results are consistent with the radial PVBT curve. An acidizing treatment is then performed.

Abstract: In one aspect, methods may include quantifying a pore-scale heterogeneity of a porous medium; determining an adjusted pore volume to breakthrough based on the pore scale heterogeneity determined; and designing a stimulating fluid treatment for the porous medium. Other aspects may include the development of a wellbore stimulation methodology that allows stimulation fluid breakthrough curves of differing formation samples to be plotted as a single curve that accounts for the varied pore structure of the respective samples.

Abstract: Oilfield treatment compositions contain water, hydrochloric acid at a concentration between 15 wt % and 45.7 wt % and a first fixing agent. The first fixing agent comprises urea, a urea derivative or both. The molar ratio between the first fixing agent and water may be higher than or equal to 0.5, and urea is the dominant solvent species in the compositions. In these compositions the first fixing agent provides corrosion inhibition when exposed to steel. The compositions may also contain a second fixing agent and an inhibitor aid.
