... in Equations (1) , ( 2 ) and ( 3 ). The main task of this work was to study the effect of Benzotriazole as a corrosion inhibitor in SBM system. Parameters examined in this work include: rheological properties, fluid loss, coefficient of friction (CoF) and corrosion penetration rate. Detailed experimental...

... Abstract ‘Green’ corrosion inhibitors derived from plant materials provide environmentally friendly alternatives to conventional corrosion inhibitors. They are also much cheaper if using a biomass waste stream or abundant plant material as the source material. There are many examples...

... Abstract This paper describes a staged acid corrosion inhibition concept for application in matrix acidizing treatments. The approach optimizes the performance of acid corrosion inhibitor (ACI) formulations used to protect coiled tubing (CT) and downhole casing during acid injection...

... Abstract Laboratory-based assessments of corrosion inhibitors for chemical qualification generally rely on approaches designed to replicate all key aspects of the corroding environment (ppCO 2 , field crude, brine composition, system temperature, pressure, wall shear, etc.). However, the time...

... Abstract Hydrocarbon chain, hydrophobic in nature, plays an important role in the efficiency of corrosion inhibitors. Increasing hydrocarbon chain length in a corrosion inhibitor tends to increase its inhibition efficiency (IE) but decrease its solubility in aqueous solutions. In this study...

... Abstract Measurement and interpretation of corrosion inhibitor residuals in a mature offshore gas/condensate field could not be reconciled with field data leading to the identification of a potential infrastructure integrity threat that mandated understanding. The field had recently...

... scavenger was incorporated into the incumbent subsea corrosion inhibitor. The work included identification of suitable multiphase H 2 S scavenging chemistry, tailoring of the multipurpose chemical to retain corrosion inhibition properties, and confirmation that this new chemistry did not deleteriously...

... Abstract Typically, the concentration of corrosion inhibitor levels in field fluids is routinely monitored. Understanding the level of corrosion inhibitor can provide information on the correct functioning of chemical injection pumps as well as determine the effects of changing system...

... to corrosion and erosion under extremely high shear conditions, and how effectively (or not) film-forming corrosion inhibitors perform. The application of these advanced laboratory techniques is currently playing a vital role in evaluating suitable methods for preventing corrosion under very challenging...

... in the presence of HAc and MEG in CO 2 saturated environment were investigated at 25°C and 80°C using 3.5% wt. NaCl solution in a semi-circulated loop setup. Weight loss and electrochemical measurements using linear polarization resistance (LPR) were used to evaluate the efficiencies of two corrosion inhibitor...

.... Strictly anoxic conditions are crucial for evaluating efficiency and degradation of corrosion inhibitors because dissolved oxygen may interfere and even react with corrosion inhibitors under production temperatures and pressures. Flow-through corrosion tests were performed for 3 weeks at 200 °C and 1,380...

... surfaces of the pipe which may not be protected by conventional corrosion inhibitors. The dissolution of corrosive gases present in the gas stream (mainly CO 2 and/or H 2 S) into the condensed water can result in severe general or localised corrosion. The design and testing of inhibitors to protect...

... of a corrosion inhibitor solution to protect Ti alloys against HF-acid attack is presented. Different metallurgical specimens (Ti, chrome, carbon (low or high) steel) were exposed to an HF-acid fluid based on a sodium-containing aminopolycarboxylic acid (APCA-Na) chelating agent. The Ti specimens (Grade-1...
