The main goal of this work is to investigate the corrosiveness of different petroleum fractions distilled from acidic crude oil “A” at 150 to 370oC (302 to 698oF) and to find effective measures for diminishing the corrosiveness of aggressive fractions.

This study describes the functionalization of a hybrid sol-gel polymeric coating with MOLY or ZAPP corrosion inhibitors and viable endospores of Bacillus licheniformis isolate (B6).
In the current study, mild steel specimens (API 5L X65) were exposed to a 1 wt% NaCl solution sparged at 0.096 MPa pCO2 and 15 ×10-6 MPa or less pH2S (≤ 150 ppm H2S/CO2).
Slow strain rate tests were conducted to study the SCC behavior of plain and welded UNS K02700 grade mild steel exposed to an artificial concrete pore water solution. Tests were performed under anoxic conditions at 140°C, a constant strain rate of 5 × 10-7 s-1 and open circuit potential.
A comprehensive parametric study was performed using a small-scale laboratory setup with the aim of investigating the occurrence of localized corrosion of mild steel in marginally sour environments.
The increased corrosion rates of mild steel in acidic solutions in the presence of CO2, previously associated with carbonic acid direct reduction, are in fact due to the increased rate of iron dissolution in the presence of CO2
A series of experiments was conducted in a large-scale multi-phase flow loop to investigate the threshold level of H2S leading to localized attack on mild steel in CO2 saturated aqueous solution with 1%wt NaCl at 40°C.
This paper describes the performance of film persistent corrosion inhibitors that are effective at fairly high temperatures and in systems that see large amounts of carbon dioxide (CO2). Use of batch treatment with the correct chemical, at the proper frequency resulted in substantial decrease in operating cost.
In recent years the oil and gas industry has made significant commitments to carbon reduction.1 Aligned with the goal of decreasing carbon emissions the authors have developed a corrosion inhibitor (CI-1) that is intended to protect scCO2 systems that are wet or water contaminated (1000 ppm).2 The development and composition of this corrosion inhibitor (CI) for dry scCO2 is reported elsewhere.2,3 While chemical companies have been treating high water cut, production enhanced, CO2 floods (i.e. enhanced oil recovery [EOR]) for several decades there were no inhibitors designed specifically for CO2 disposal systems or wet scCO2 systems producing CO2 for sale.4
H2S corrosion, also known as sour corrosion, is one of the most researched types of metal degradation in oil and gas transmission pipelines requiring a wide range of environmental conditions and detailed surface analysis techniques. This is because localized or pitting corrosion is known to be the main type of corrosion failure in sour environments which caused 12% of all oilfield corrosion incidents according to a report from 1996. Therefore, control and reduction of this type of corrosion could prevent such failures in oil and gas industries, and significantly enhance asset integrity while reducing maintenance costs as well as eliminating environmental damage.
