Results of inhibitor performance at slug flow in a 101.6 mm inner diameter horizontal pipeline. Electrochemical Impedance Spectroscopy (EIS) and scanning electrom microscope (SEM) techniques are used to reveal that the strong bubble impact, high shear stress and turbulent intensity are the reasons for a poor performance of inhibitor.
Nickel-base alloys 718, 725, and 925 are commonly used in oil and natural gas production. Being heavily alloyed multi-component systems; these materials require special consideration for processing and heat treatments. This paper shows the effect of intergranular precipitates on mechanical properties and slow strain rate (SSR) test results in sour oil patch environments.
The process of determining the fluid compatibility (FC) of elastomers and how compatibility affects material selection for downhole applications. Effects of completion fluids (Bromides and Formates) on elastomers. Elastomer samples were conditioned at temperatures from 175°F (80°C) to 380°F (193°C) for up to 3 weeks.
Several well casings were selected as candidates for down hole inspection logs to determine if cathodic protection could be a solution to the external corrosion problem. "Test" cathodic protection systems were installed. Based on logging results and economic evaluation, implementation of a cathodic protection pilot project commenced.
