Title:
NOVEL MODIFIED ACID COMPOSITIONS AS ALTERNATIVES TO CONVENTIONAL ACIDS IN OIL AND GAS INDUSTRIES
Document Type and Number:
Japanese Patent JP2022191294
Kind Code:
A
Abstract:
To provide aqueous modified acid compositions capable of improving, in the oil and gas industries, corrosion, logistics and handling, human and environmental exposure, reaction rates, toxicity levels, biodegradation tendencies and formation/fluid compatibility and facility and/or production and water treatment infrastructure operational compatibility.SOLUTION: An aqueous modified acid composition comprises hydrochloric acid and an ethanolamine, where the molar ratio of the hydrochloric acid to the ethanolamine is from 3 to 10 inclusive, and has a pH less than 1 and stability up to the temperature of 190°C. The composition may further comprise a metal iodide or iodate.SELECTED DRAWING: None
