Abstract: The invention relates to compositions, methods and preparation of such compositions to protect metals from corrosion, especially acid corrosion. The compositions of this invention may be added to acids to protect metals from their corrosive influence, particularly at elevated temperatures. These compositions are of particular utility in the oil and gas (petroleum) industry. Also disclosed are “corrosion inhibition intensifiers” to enhance the corrosion inhibition properties of other corrosion inhibitors. Formulations which control ferric ions in acidic solutions are also disclosed. These may be combined with inhibited acids and some compositions provide both corrosion inhibition and ferric ion control.

Abstract: A recoverable instant thickening acid and its reusing method is usable for the recycling and reusing of a gas well carbonate reservoir acidizing fluid and production stimulation operation. The recoverable instant thickening acid includes the following components in weight percentage: 1.5-3 parts of a thickener, 0.5-3 parts of potassium chloride and 100 parts of a hydrochloric acid solution, wherein the thickener is a mixture composed of a mass ratio of 40%-70% of N-lauryl-N′-hydroxyethyl-N′-hydroxypropyl ethylenediamine propionate or its derivatives, 4%-12% of ethanol and 18%-56% of water. With the thickening acid for performing an acidizing treatment, the residual acid solution can be re-prepared as a thickening acid for an acidizing treatment without a chemical treatment, assisting the green and environmentally friendly production and sustainable development of gas fields.

Abstract: In a subterranean formation, complexation of metal ions can often be desirable in order to mitigate reactivity of the metal ions. However, many chelating agents used for this purpose are commercially manufactured in an alkali metal salt form that may not be entirely suitable for use downhole. The working pH range of some types of chelating agents may also be limiting. Accordingly, methods for treating a subterranean formation can comprise: providing an acidic treatment fluid comprising a sulfonated iminodiacetic acid; introducing the acidic treatment fluid into a subterranean formation; and at least partially dissolving an acid-reactive substance in the subterranean formation while complexing one or more metal ions with the sulfonated iminodiacetic acid.
