Oil recovery efficiency can be increased by applying the enhanced oil recovery (EOR) processes, which are based on the improvement of mobility ratio, reduction of interfacial tension between oil and water, wettability alteration, reduction of oil viscosity, formation of oil banks, and so forth. This book describes the different EOR methods and their mechanisms, which are traditionally used after conventional primary and secondary processes. The present scenario of different EOR processes, at both the field application stage and research stage, is also covered. Further, it discusses some of the recent advances in EOR processes such as low-salinity water flooding, the application of nanotechnology in EOR, microbial EOR, carbonated water injection, etc. Features: Comprehensive coverage of all enhanced oil recovery (EOR) methods Discussion of reservoir rock and fluid characteristics Illustration of steps in design and field implementation as well as the screening criteria for process selection Coverage of novel topics of nanotechnology in EOR and hybrid EOR method and low-salinity waterfloods Emphasis on recent technologies, feasibility, and implementation of hybrid technologiesThis book is aimed at graduate students, professionals, researchers, chemists, and personnel involved in petroleum engineering, chemical engineering, surfactant manufacturing, polymer manufacturing, oil/gas service companies, and carbon capture and utilization.

Das Buch umfasst die Herstellung eines sulfonierten Tensids auf Rizinus lbasis und eines polymeren Tensids f r die Anwendung bei der verbesserten lgewinnung. Das entwickelte Tensid und das polymere Tensid werden durch FTIR, FE-SEM, EDX, TGA und DLS-Analyse charakterisiert. Die Leistung des synthetisierten Tensids und des entsprechenden polymeren Tensids als chemisches Mittel f r die verbesserte lgewinnung wurde durch Messung der Grenzfl chenspannung (IFT) zwischen Roh l und w ssrigen Tensidl sungen, des rheologischen Verhaltens und des Kontaktwinkels gegen ber der Sandsteinoberfl che untersucht. Kernflutungsexperimente wurden in einem Sand-Pack-System durchgef hrt, und durch die Injektion von 0,5 Porenvolumina von Tensid-Slugs nach der konventionellen Wasserflutung wurde eine zus tzliche Ausbeute von 26-30 % des urspr nglichen lgehalts (OOIP) erzielt.

Il libro comprende la preparazione di un tensioattivo solfonato a base di olio di ricino e di un tensioattivo polimerico per l'applicazione nel recupero avanzato del petrolio. Il tensioattivo e il tensioattivo polimerico sviluppati sono stati caratterizzati mediante analisi FTIR, FE-SEM, EDX, TGA e DLS. Le prestazioni del tensioattivo sintetizzato e del corrispondente tensioattivo polimerico come agente chimico per il recupero avanzato del petrolio sono state studiate misurando la tensione interfacciale (IFT) tra il petrolio greggio e le soluzioni acquose di tensioattivo, il comportamento reologico e l'angolo di contatto con la superficie dell'arenaria. Sono stati condotti esperimenti di allagamento del nucleo nel sistema sand-pack e si ottenuto un recupero aggiuntivo del 26-30% dell'olio originale in posto (OOIP) con l'iniezione di un volume di 0,5 pori di slug di tensioattivo dopo l'allagamento convenzionale con acqua.

O surfactante desenvolvido e o surfactante polim rico s o caracterizados por FTIR, FE-SEM, EDX, TGA, an lise DLS. O desempenho do tensioativo sintetizado e do correspondente tensioativo polim rico como agente qu mico para a recupera o melhorada de petr leo foi estudado atrav s da medi o da tens o interfacial (IFT) entre o petr leo bruto e as solu es aquosas de tensioactivos, do comportamento reol gico e do ngulo de contacto contra a superf cie do arenito. Foram realizadas experi ncias de inunda o de n cleos no sistema sand-pack e obteve-se uma recupera o adicional de 26-30% do petr leo original no local (OOIP) atrav s da inje o de 0,5 volume de poros de proj cteis de tensioativo ap s a inunda o convencional com gua.

This book focuses on the use of nanoemulsion in enhanced oil recovery, along with a brief information about the emulsion and its types and different physico-chemical properties used to analyse the efficiency of the emulsions and nanoemulsions. The author discussed about the nanoemulsion, classification of emulsions and nanoemulsion and use of nanoemulsions in petroleum industry. A special attention has been laid on nanoemulsion and its advantages over commercial product, physico-chemical properties like emulsification, interfacial tension and wettability alteration study as a screening criteria for application in EOR. Given this content, this book offers an assessment for the undergraduate and postgraduate students of petroleum and chemical engineering along with the researchers working in the field of EOR. It is a subject of interest for oil and gas industry professionals.

This book focuses on the use of natural surfactants in enhanced oil recovery, providing an overview of surfactants, their types, and different physical–chemical properties used to analyse the efficiency of surfactants. Natural surfactants discuss the history of the surfactants, their classification, and the use of surfactants in petroleum industry. Special attention has been paid to natural surfactants and their advantages over synthetic surfactants, including analysing their properties such as emulsification, interfacial tension, and wettability and how these can be used in EOR. This book offers an overview for researchers and graduate students in the fields of petroleum and chemical engineering, as well as oil and gas industry professionals.
