FORMULATIONS FOR CORROSION INHIBITION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18680934 titled 'FORMULATIONS FOR CORROSION INHIBITION
The abstract describes an aqueous acid composition for use in matrix acidizing treatments, containing an acid, a polymeric acid corrosion inhibitor, and an acid corrosion inhibitor intensifier.
- The acid corrosion inhibitor includes iodide ions and metal ions such as copper, silver, bismuth, or antimony, with a molar ratio of metal ions to iodide ions of 1:X, where X is greater than or equal to 2.
- The polymer of the polymeric acid corrosion inhibitor has a molecular weight less than 100,000 g/mol.
Potential Applications: - Matrix acidizing treatments in the oil and gas industry - Corrosion inhibition in acidic environments
Problems Solved: - Corrosion of metal surfaces during acid treatments - Enhanced performance and longevity of acidizing treatments
Benefits: - Improved corrosion inhibition - Extended equipment lifespan - Enhanced treatment effectiveness
Commercial Applications: Title: Advanced Aqueous Acid Composition for Enhanced Corrosion Inhibition This technology can be utilized in the oil and gas industry for matrix acidizing treatments, providing superior corrosion protection and improving treatment outcomes.
Questions about the technology: 1. How does the molar ratio of metal ions to iodide ions impact corrosion inhibition? 2. What are the specific advantages of using a polymeric acid corrosion inhibitor with a molecular weight less than 100,000 g/mol?
Original Abstract Submitted
An aqueous acid composition that may be used, for example, in a matrix acidizing treatment can include an acid, a polymeric acid corrosion inhibitor, and an acid corrosion inhibitor intensifier. The acid corrosion inhibitor can include iodide ions and metal ions, with the metal ions being one or more of copper, silver, bismuth, or antimony. The molar ratio of metal ions to iodide ions can be 1:X, where X is greater than or equal to 2. The polymer of the polymeric acid corrosion inhibitor can have a molecular weight less than 100,000 g/mol.
