Change in absorbance of the aqueous scale inhibitor solution.
Compared with the blank sample, inhibitor solution shows stronger inhibition to hydration and swelling of bentonite.
The aqueous scale inhibitor solution was prepared by dissolving the chemical reagents at different mass concentrations.
EDX spectra were used to determine the elements present on MS surface before and after exposure to the inhibitor solution.
The adsorption and desorption ability of the inhibitors was studied by injecting aqueous scale inhibitor solution into the core samples.
In this process, a scale inhibitor solution is injected down a producer well into the near wellbore formation.
Inclusion of polyethylene oxide into a kinetic inhibitor solution was found to enhance the performance of the inhibitor.
By increasing the inhibitor concentrations, weight loss of MS in case of inhibitor solutions is lower that of free inhibitor solution in the same period of time.
Figure 1 illustrates an apparatus for injecting formation waters and the aqueous scale inhibitor solution into the core samples at desired reservoir conditions.
The enzyme inhibitor solution was pre-incubated for 30 min at 37 °C before the addition of substrate to start the reaction.
The corrosion activity of the used scale inhibitors was evaluated through the mass reduction of reference samples after their immersion in the aqueous scale inhibitor solution.
