AI Technical Summary
Technical Problem
Current scale inhibitors, such as HEMPA, are not compatible with harsh conditions in oil wells, leading to short squeeze lifetimes and increased frequency of treatments, which results in decreased production and economic inefficiency.
Method used
A nanoparticle-well treatment additive complex comprising amine functionalized silica nanoparticles with a well treatment additive, such as HEMPA, releasably attached through ionic, covalent, or Van der Walls interactions, providing extended release and compatibility in high salinity, calcium, and temperature conditions.
Benefits of technology
The complex achieves a squeeze lifetime at least twice that of standalone HEMPA, with controlled release over extended periods, reducing treatment frequency and enhancing economic efficiency.
