... Abstract Silicate scaling is a concern that could result in formation damage and flow assurance issue. Phosphonates and phosphino-polyacrylates are widely used to treat many types of scale but they are not intended to treat silicate scale. Besides that, these inhibitors may have been considered...

... it to provide steric stabilization. Abstract Scale inhibitor squeeze (SISQ) treatment is an established method for offshore fields which allows an extended effectiveness of the scale inhibitors in preventing scale deposition over time. Some of the main issues in SISQ campaign is the short squeeze lifetime...

... by preventive measures in scale management. The most effective technique for mitigating downhole scale formation is through the application of scale inhibitor solution injected into the near wellbore of the formation. Chemical selection is crucial to ensure effectiveness and longevity of the treatment...

The positive impact on oil production optimization resulting from these strategies will also be discussed and the advantages, lessons learned, and constraints of this work. Conventionally, corrosion and scale chemical inhibitors are deployed through capillary lines...

... line due to production after avoidance typhoon. We discuss the variation of temperature profile and concentration of ethylene glycol during restart operation. The concentration variation of the ethylene glycol on the induced flow show after restart operation that the hydrate inhibitor satisfies...

... were predicted quantitatively. Meanwhile, the hydrate reformation management strategies through optimization of production design parameters in combination with hydrate inhibitor injection were proposed and discussed in detail. The results indicate that the risk of hydrate reformation is the highest...

... 1.0 atm. were performed in a 0.5 L glass container. The coupon was immersed in HCl solutions in the absence or presence of a series of concentrations of the different inhibitors for 4 hours, respectively. Two identical coupons were used in each test, and the mean value of the corrosion rate...

... an effective mitigation strategy, it is essential to understand the location and severity of scaling, and the performance of scale inhibitor under specific operation conditions. In the work reported herein, the dynamic scale loop tests were performed to evaluate the severity of scale deposition at different...

... into deepwater reserves. Common mitigation measures for hydrate formation and plugging include the traditional control methods of injecting thermodynamic inhibitor that assure the operational conditions are outside the hydrate risk region. However, inhibitor injection rates are typically designed based...

... Abstract Dual function hydrate inhibitor (DFI) is envisaged to provide superior inhibition performances for controlling hydrate formation in comparison to conventional thermodynamic (THI) and kinetic hydrate (KHI) inhibitors. In this work, the performance of DFI was evaluated in high pressure...

... Abstract This paper describes the change of the chemical flow assurance mitigation strategy for a major deep water waxy crude oil pipeline in SE Asia. The case relates to an application of a Pour Point Depressant (PPD)/Wax Inhibitor (WI) chemical that is critical in maintaining subsea flow...

... Abstract Wellbore stability in high reactive shales is one of the operator challenges leading them to use OBM and WBM with different inhibitors such as KCL, glycols, amines ant etc. Environmental concerns restrict the OBM and Amines usages, but knowledge shortage in relation with inhibition...

...). The utilization of carbon steel in the design of piping and equipment makes them susceptible to corrosion. Injection of corrosion inhibitor (CI) is recommended to minimize material degradation, and correct selection of CI is key to ensure corrosion management is effective and efficient.

... Abstract This work was motivated for establishing a robust asphaltene flow assurance engineering using asphaltene inhibitor to mitigate the risk of asphaltene precipitation in tubing. For this purpose, the best candidate was selected through asphaltene dispersant test (ADT). Furthermore, its...
