... Abstract Scale inhibitors have been widely used in oil and gas production as well as oil processing plants to control the formation of mineral scales. However, most scale inhibitors tend to lose efficiency as scaling temperatures above 400°F due to the thermal degradation of the chemicals...

...Discussion and Conclusions We have successfully tested the idea of scale inhibitor (SI) injection with the MEA-based alkali-surfactant (AS) formulation as an alternative to make-up water softening and scale squeezing of the producer wells. The main results of the Scaling Inhibitor field trial...

... showed low formation damage and scaling tendencies. In the coreflow tests at 300°F, a regained permeability of greater than 95% was obtained. In the scaling tests without the presence of scale inhibitor at 300°F, traceable (<0.01 wt %) amount of scale was observed in the mixture of the nanofiltered...

... Abstract A strategy combining fracturing and downhole scale inhibitor squeeze treatments was employed in an extremely tight high-temperature gas reservoir (200°C) with calcite and sulfate scaling problems. Challenges included developing a scale inhibitor that is thermally stable at this high...

... ions (exist at high concentrations in various formations), poses a serious problem. To effectively mitigate this serious scale issue, a combination of water treatment and chemical scale inhibitor is recommended. Nanofiltration (NF) technology has proven to be a reliable water treatment method...

.... The new solid inhibitor product was made by adsorbing scale inhibitor onto a high-strength, proppant-sized substrate with a large surface area. The high-strength substrate were prepared by sol-gel chemistry through hydrolysis of aluminum alkoxides and formation of particles that are calcined...

... scaling tendencies, an in-house multidisciplinary team has performed extensive collaborative research to identify a scale inhibitor appropriate for Arabian Gulf seawater and formation water. Scale precipitation can be further mitigated by filtering the seawater with a nanofiltration system to dramatically...

The mechanisms of scale inhibitor retention when phosphonate, polymer, and vinyl sulphonate co-polymer inhibitor squeeze treatments are applied in this carbonate reservoir...

... significant improvement to chemical management processes. The first is the use of a novel, best-in-class scale inhibitor chemistry. Two years were spent in an industry wide search as well as developing and extensively testing the chemical in the laboratory. The new chemical is now deployed on over 75...
