Enhanced oil recovery

Schizophyllan is a natural polysaccharide that has shown great potential as enhanced oil recovery (EOR) polymer for high-temperature, high-salinity reservoirs. Nevertheless, the adsorption behavior of schizophyllan over carbonate minerals remains ambiguous element towards its EOR applications.

Enhanced oil recovery (EOR) implementation at field scale is complex. Therefore, pilot applications are usually conducted before field execution. This paper introduces a pilot project successfully applied for the Lower Miocene, Bach Ho field. Topics covered include: (i) pilot area selection, (ii) chemical preparation, (iii) specification and pilot design for execution, (iv) implementation, (v) pilot observation and interpretation, (vi) efficiency evaluation.

Seawater injection into chalk-reservoirs on the Norwegian Continental Shelf has increased the oil recovery and reduced seabed subsidence, but not eliminated it. Therefore, understanding rock–fluid interactions is paramount to optimize water injection, predict and control water-induced compaction.

Thermostable and highly water-soluble polymers are essential for polymer flooding — one of the most effective methods used in the enhanced oil recovery (EOR) in hightemperature (HT) offshore reservoirs. In this research, the copolymerization reaction of acrylamide (AM) and N-vinylpyrrolidone (NVP) monomers were performed via a freeradical mechanism induced by gamma-rays (γ-rays) irradiation.

This paper presents all the production technology solutions that apply to the marginal heavy oil field offshore Vietnam. One of the major solutions is the electric submersible pump (ESP) and gas-lift (GL) combination method to enhance the wellbore lifting efficiency. In doing so, a series of solutions to improve heavy oil recovery have been conducted from design to pilot test whilst optimising the economic yield over the field life. Among them, the application of ESP and GL combination plays as the key driver to reinforce good production performance.

This paper reviews the mechanisms of oil release and the use of microbes and their metabolic products to enhance oil recovery. Alteration of oil/rock/water interfacial tensions properties and changes in flow behaviour assist the enhancement of oil recovery. Oil recovery can be improved by injecting gases and solvents or by stimulating their production by reservoir microflora in situ for reservoir repressurization and carbonate rock dissolution.

The bio-recovery of three different oil-polluted tropical soils – RS (oil-polluted soil sample from River state), LS (soil sample from NNPC depot, Lagos) and POS (oil-polluted soil sample from Oriade L.G.A., Lagos) by manure amendment was studied for eight weeks. The rates of crude oil biodegradation after manure application as quantified by Gas chromatographic analysis of residual total petroleum hydrocarbon (TPH) showed the same trend of decrease in the total petroleum hydrocarbons in both the LS and RS series.

Surfactants are widely used in the petroleum industry as one kind of Enhanced Oil Recovery methods (EOR). The oil sands mines in Northern Alberta are the largest one in the world. Due to using sodium hydroxide in bitumen extraction process, there are a lot of surfactant molecules in the tailing water. The surfactants from oil sands industry have brought a potential threat to the environment and human health.

Inducing calcium carbonate precipitation is another important function of urease in nature. The process takes advantage of the supply of carbonate ions derived from urea hydrolysis and of an increase in pH generated by the reaction, effects that in the presence of Ca2+ ions lead to the precipitation of CaCO3.

CO2 injection has recently been shown to provide significant enhanced oil recovery from naturally fractured reservoirs 1 . Li et al. (2000) performed CO2 injection at 1750 psig on artificially-fractured cores after water flooding in a dead-oil system. Gravity drainage was suggested to be the dominant recovery mechanism in these tests, with significant tertiary oil recovery after water flooding. The authors observed that the recovery of initial oil at the start of the CO2 injection declined as the rock permeability decreased and the initial water saturation increased. Darvish et al.

Developing a book of any magnitude requires time away from family and friends, so as we finish this one, we must confess that despite the obvious intellectual and personal satisfactions we enjoyed while writing this book, it was not always a pleasant experience. The book’s contents are for the most part the result of scribbling on napkins over numerous macchiati and espressos away from the office at different posts over the years. As researchers and consultants, perhaps our most creative moments arose during lengthy informal, and somewhat dreamy, discussions about enhanced oil recovery.

I am enormously grateful to all of authors who have contributed to this volume on gas– liquid foam. One of the great pleasures of working with such accomplished scientists and engineers from industry and academia is that everybody has known the level at which to pitch their contributions. Special thanks are due to Laurie Schramm who, along with co-authors, has contributed two chapters on foams in enhanced oil recovery and flotation of oil sands, and to Thomas Martin who endured initial confusion upon my part to produce a first class chapter on firefighting foams....

This book is intended for graduate students, researchers, and reservoir engineers who want to understand the mathematical description of the chromatographic mechanisms that are the basis for gas injection processes for enhanced oil recovery. Readers familiar with the calculus of partial derivatives and properties of matrices (including eigenvalues and eigenvectors) should have no trouble following the mathematical development of the material presented.
