The corrosion is an (unwanted) reaction of materials with substances present in their environment. In the case of iron this reaction becomes visible for instance when rust forms. The reasons for this corrosion are diverse and are covered very extensively in the literature. The study of corrosion processes and their inhibition by organic inhibitors is a very active field of research. The presence of actives centres in the molecular structure has a major effect on the inhibition efficiency and consequently on the phenomenon of adsorption on some metals surface. The inhibition effect mainly depends on some physicochemical and electronic properties of the inhibitor which relate to its functional groups, steric effects, electronic density of donor atoms, and orbital character of donating electrons. Corrosion inhibition of has been elucidated by means of theory DFT-derived reactivity indexes. The calculated quantum chemical parameters have already proven to be very useful in determining the molecular structure as well as elucidating the electronic structure and reactivity. Thus, it has become a common practice to carry out quantum chemical calculations in corrosion inhibition studies.

Many experts working in the field of corrosion work in laboratories experimentally with long-term procedures and high costs by making changes in the structures of new corrosion inhibitors or existing inhibitors. Advances in computational chemistry and computer software in recent years combine corrosion prevention studies with theoretical chemistry, enabling fast, cheap and highly accurate research. Researchers working in this field can now predict the electronic, molecular and adsorption properties of anti-corrosion molecules at the molecular level with density functional theory (DFT) and Molecular Dynamics Simulation. This section includes: introduction, corrosion mechanisms, introduction to corrosion inhibitors, density functional theory (DFT) and corrosion applications, Molecular Dynamics Simulation, DFT and Molecular Dynamics Simulation applications of the effectiveness of the selected corrosion inhibitor and results. The theoretical data obtained by both the DFT approach and the molecular dynamics simulation approach showed that the corrosion inhibition efficiency order against iron corrosion for the studied Schiff bases and derivatives can be presented as: DBAMTT> SAMTT> AMTT. HOMO energy value of DBAMTT has ,àí8,18144, HOMO energy value of SAMTT has ,àí8,09001, and AMTT has ,àí8,01518 in HF/6,Äì31++G** basis set.

Microorganisms can be both beneficial and harmful to the oil and gas industry and therefore there is an increasing need for the oil industry to characterize, quantify and monitor microbial communities in real time. Oilfield Microbiology offers a fundamental insight into how molecular microbiological methods have enabled researchers in the field to analyze and quantify in situ microbial communities and their activities in response to changing environmental conditions. Such information is fundamental to the oil industry to employ more directed, cost-effective strategies to prevent the major problems associated with deleterious microbial activities (e.g., souring and biocorrosion), as well as to encourage beneficial microbe activity (e.g. oil bioremediation). The aim of the book is to understand how the technological advances in molecular microbiological methods over the last two decades are now being utilized by the oil industry to address the key issues faced by the sector. This book contains a comprehensive collection of chapters written by invited experts in the field from academia and industry and provides a solid foundation of the importance of microbes to the oil and gas industry. It is aimed at microbial ecologists, molecular biologists, operators, engineers, chemists, and academics involved in the sector.
