This book describes different conventional Enhanced Oil Recovery (EOR) methods and their mechanisms along with present scenario of different EOR processes both at the field application and research stages. It includes chemical EOR, nanotechnology in EOR, low salinity water flooding, ECBM and enhanced recovery techniques for shale oil/gas.

Das Buch umfasst die Herstellung eines sulfonierten Tensids auf Rizinusölbasis und eines polymeren Tensids für die Anwendung bei der verbesserten Ölgewinnung. 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 für die verbesserte Ölgewinnung wurde durch Messung der Grenzflächenspannung (IFT) zwischen Rohöl und wässrigen Tensidlösungen, des rheologischen Verhaltens und des Kontaktwinkels gegenüber der Sandsteinoberfläche untersucht. Kernflutungsexperimente wurden in einem Sand-Pack-System durchgeführt, und durch die Injektion von 0,5 Porenvolumina von Tensid-Slugs nach der konventionellen Wasserflutung wurde eine zusätzliche Ausbeute von 26-30 % des ursprünglichen Ölgehalts (OOIP) erzielt.

O livro engloba a preparação de um tensioativo sulfonado à base de óleo de rícino e de um tensioativo polimérico para aplicação na recuperação avançada de petróleo. O surfactante desenvolvido e o surfactante polimérico são caracterizados por FTIR, FE-SEM, EDX, TGA, análise DLS. O desempenho do tensioativo sintetizado e do correspondente tensioativo polimérico como agente químico para a recuperação melhorada de petróleo foi estudado através da medição da tensão interfacial (IFT) entre o petróleo bruto e as soluções aquosas de tensioactivos, do comportamento reológico e do ângulo de contacto contra a superfície do arenito. Foram realizadas experiências de inundação de núcleos no sistema sand-pack e obteve-se uma recuperação adicional de 26-30% do petróleo original no local (OOIP) através da injeção de 0,5 volume de poros de projécteis de tensioativo após a inundação convencional com água.

The book encompasses synthesis of asymmetric polymeric mixed matrix ultrafiltration (UF) flat sheet membranes using polysulfone (PSf) polymer, N-methyl-2-pyrrolidone (NMP) solvent and various additives like bentonite, silica, polymer-grafted-bentonite for the enhancement of the antifouling properties of membranes so that the prepared membranes can be successfully employed for the removal of oil from oily wastewater, generated during oil and gas production. The book comprises of: ¿ Characterization of silica and bentonite nanoparticles ¿ Preparation and characterization of nanoparticle mixed matrix PSf UF membranes ¿ Preparation and characterization of synthetic produced water (SPW) ¿ Characterization of oilfield produced water ¿ Testing and performance studies of silica and bentonite based mixed matrix membrane using synthetic produced water ¿ Preparation of polymer-grafted bentonite nanoparticles ¿ Preparation and characterization of polymer-g-bentonite based PSf UF membranes ¿ Purification of oilfield produced water using polymer-g-bentonite based UF membranes.
