... properties Prevent and Remove Halite inhibitor Halite scale inhibitor is a polymeric based inhibitor designed to control and mitigate halite scaling issues. The product exhibits excellent brine tolerance and calcium compatibility in excess of 50,000 mg/L. The halite scale inhibitor, increase...

... 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...

... Abstract The hydrate-inhibiting performance of a natural plant-based polysaccharide iota-carrageenan is evaluated as a standalone inhibitor and as a synergist with two well-known kinetic hydrate inhibitors (KHIs), polyvinyl caprolactam (PVCap) and polyvinylpyrrolidone (PVP), in order to achieve...

... Abstract Asphaltenes are a global flow assurance problem responsible for reduced production and increased operating costs in many oilfields. Asphaltene inhibitor programs are needed to manage problems and increase operational profitability. Improvements are needed in both developing new...

... regulations prohibit the disposal of greater than 3,000 ppm chloride on lease or 1,000 ppm chloride off lease. The hazardous nature of choline chloride restricts its use as shale inhibitor for water-based fluids. Nanosilica Based Shale Inhibitor (NSBSI) has been developed to mitigate the difficulties in clay...

... Abstract Metal Oxide Nanoparticles (MONPs) comparison has been used for the first time as Nanoshale inhibitors in water-Based Drilling Fluids. These Nanoshale inhibitors used in this study eliminate the use of toxic high potassium chloride (KCl) concentration in shale drilling operations...

... or even complete blockage. The objective of this work was to evaluate a recently developed, novel high-pressure high-temperature (HPHT) quartz crystal microbalance (QCM) set-up for the testing of asphaltene deposition inhibitors. Developed within a joint industry project (JIP) aimed at improved...

...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...

... Abstract Amid concerns over negative the environmental impacts of offshore chemicals, Baker Hughes explored new chemistries to develop environmentally friendly kinetic hydrate inhibitors (KHI). Our efforts were focused on improving biodegradability and toxicity of KHIs to meet environmental...

... Abstract In the last decade, hydrophilic Ionic liquids have been emerged as an additive in drilling fluids for clay swelling inhibition. However, the application of hydrophobic Ionic liquids as a clay swelling inhibitor have not been investigated. In this study, the combination of hydrophobic...

... involves bullheading a corrosion inhibitor batch treatment. However, high costs and low effectiveness are driving a shift from batch treatments to continuous downhole treatment techniques. This paper describes the process of converting to continuous downhole treatments. Methods, Procedures, Process...

... 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...

... in conjunction with HTHP stimulation treatments where compatibility of the scale control chemical with fracturing fluids is critical, and when longer-term inhibition performance is desired. A new solid inhibitor was developed for this purpose and applied in multiple wells in the Krishna Godavari (KG) basin...
