In a bioinspired approach, we have used (as scale inhibitors) several non-toxic, “green” polyelectrolytes that possess “active” chemical moieties, capable of stabilizing silicic acid, for a prolonged time period. These additives include either neutral or charged polymers that stabilize two soluble forms of “Si”, silicic and disilicic acids.

A commercial cellulose-based polymer (carboxymethyl cellulose sodium) was tested to see whether it could be utilized by an oilfield biofilm consortium including sulfate reducing bacteria.
Assessment was performed on the use of polymer-based materials or liners for large solids particle slurry applications. The study was conducted in a pilot-scale horizontal slurry flow loop using two different solids: sand and rocks.
Often when a polymer coating failure occurs, the concrete quality and integrity are questioned. Core samples removed from the concrete slab are examined using petrographic techniques to help determine the cause of the coating failure. The basics of the petrographic examination, the equipment used and what information it can provide are presented.
An understanding of the relationship between color and our environment remains an area in which much research has been conducted; yet, we are ever fascinated with the topic of color and the nuances it has yet to unfold. Our work aims to begin a dialogue regarding color trends, color application in an environment, the psychological impact of color and an understanding of the balance between these philosophies.
Picture for Challenges and Solutions with Polymer, Polymer-Like Carbon, and Diamond-Like Carbon Coatings Against Geothermal Scaling and Corrosion Picture for Challenges and Solutions with Polymer, Polymer-Like Carbon, and Diamond-Like Carbon Coatings Against Geothermal Scaling and Corrosion.
Silicone room temperature vulcanizing (RTV) polymer based coatings were designed with maintenance, and extending asset design life in mind. This technology can be tailored to be used as the backbone for a wide variety of coating applications by taking advantage of the inherent properties of RTV silicone.
Some of the toughest environments for protective coatings to withstand are seen in the power industry, particularly within the flue gas desulfurization (FGD) process. Temperatures within the different areas throughout the system may reach 350-450°F (177-232°C) and then be cooled to ambient temperatures upon shutdown of the unit.
Operators have used a variety of strategies to maximize oil well productivity. One such technology is matrix acidizing, which is intended to boost fluid output by improving the drainage efficiency of the reservoir rock surrounding the wellbore [1]. It comprises injecting a strong acid solution into an oil well in order to dissolve and remove formation damage caused by drilling and completion operations, as well as to establish new production paths in production formations [1].
HISTORICAL DOCUMENT. Process to design, install, and operate a thermoplastic-lined oilfield pipeline. For use by liner installers, owners, materials suppliers, consultants, engineering firms.
There is evidence of significant physical fouling of crude units from polymerization of MEA triazine scavenger in the presence of hydrogen sulfide. This paper highlights this new impact.
