  • Composition of water based coating with a low content of volatile organic compounds and high resistance to dirt handle, and, use of water based coating
    Patent number: 11274214
    Abstract: The present invention relates to water-based coatings compositions containing low volatiles and high resistance to the dirt grip. Such compositions contain conventional low VOC coalescing latexes which favor the evolution of hardness of films of inks and films of polymers by providing coatings with high resistance to the catch of dirt that can be used in various applications. Such coalescents are predominantly diesters with a boiling point greater than 260° C., preferably boiling point greater than 280° C., and molecular weight between 230 and 342 atomic mass units prepared from diacid and alcohol or monoacid reactions and diols.

  • VISCOELASTIC COMPOSITIONS FOR MATRIX ACIDIZING
    Publication number: 20220064519
    Abstract: Viscoelastic compositions suitable for use as diversion agents in a process for acidizing a carbonate-based subterranean oilfield formation are disclosed. The compositions comprise water, a tall oil fatty acid (TOFA)-based amidoamine betaine, a C1-C4 alcohol, and propylene glycol. The invention includes an acidizing process that utilizes a mineral acid and an effective amount of the viscoelastic composition. The viscoelastic compositions effectively divert acid flow, thereby optimizing acid utilization and minimizing acid spend. The compositions fully develop formations, stabilize and/or promote formation of worm-like micelles, and maintain a high, stable viscosity during an acidizing process. Surprisingly, the compositions perform well at low surfactant does, high pressures, and temperatures greater than 350° F. The compositions can tolerate higher levels of corrosion inhibitors than known alternatives and can be used in formations having ferric ion contents greater than 10,000 ppm.
