... includes corrosion rate forecasting and tubing lifetime, enabling proactive management of corrosion-related issues. For offshore wells, squeeze inhibitors must have high water solubility to ensure deep penetration, thermal and chemical stability to withstand downhole conditions, and strong adsorption...

..., but measurements indicate that a steady state concentration of ca. 100 mg/l has been reached. The simulations indicate that this happens when the strong alkalinity in the lean MEG approaches 1 mmol/l. If not already in place, it is recommended to inject an appropriate scale inhibitor that is effective...

... Abstract This study investigated the development of inorganic scale inhibitors for extreme application conditions in new offshore fields in Brazil, characterized by high salinity (up to 230,000 mg/L) and temperatures (120°C). Traditional scale inhibitors, including phosphonates and polymers...

... not considered feasible, the effects of the addition of a wax inhibitor was also considered using the same modelling approach. Background Theoretical Background Crude oils often contain dissolved n-paraffins and other wax forming components. At high temperatures, these components remain dissolved...

... material and the use of anticorrosive coatings. Inhibitors are also widely used as part of the injection fluids to eliminate the corrosion of infrastructure induced by its interactions with reservoir fluids and chemicals commonly appeared in offshore production. Two of the most critical types of corrosion...

..., a scale inhibitor, and a fines migration preventer into the drill-in and completion fluids. Several tests were performed to prove the concept, including return permeability using a sequence of fluids (reservoir, drill-in, and completion fluids), interfacial tension measurements, and compatibility analysis...

...) as complexing agent. The early precipitation of sulfites thanks to CaCl2 or CaCO3 addition. The chemical scale mitigation by antiscalant injection. The injection of scale inhibitors did not show any efficiency whatever the scale inhibitor and the concentration (30, 60 and 120 ppm) for process water...

... The root cause of this gunking was attributed to not using a flash-resistant solvent in the scale inhibitor package ( 2 ). Besides solvent flashing, gunking can also occur due to product instability, which was the main cause of the downhole scale inhibitor injection line in another high...

... and reservoir through a scale inhibitor squeeze (SISQ) treatment with a lifespan of 2 years. The main objective of this approach is to eliminate the need of frequent stimulation jobs to maintain the production. Several attempts of scale inhibitor pumping in the past had been applied in the operator's...

... Abstract Flow assurance problem of gas hydrate formation in subsea transportation system of crude oil is addressed in this research work. The paper depicts the synthesis and evaluation of propylene glycol quantum dots as low-dosage hydrate inhibitor (LDHI) for preventing / delaying gas hydrate...

.... Overall, the general consensus is that lower water contents, dispersed water, high shear, thermodynamic inhibitor injection, dosing of anti-agglomerants or kinetic hydrate inhibitors, higher oil viscosities, and oils with natural chemical surfactant properties can be favorable for ensuring successful...
