Sustainable world economy requires a steady supply of crude oil without any production constraints. Thus, the ever-increasing energy demand of the entire world can be mostly met through the enhanced production from crude oil from existing reservoirs. With the fact that newer reservoirs with large quantities of crude oil could not be explored at a faster pace, it will be inevitable to produce the crude oil from matured reservoirs at an affordable cost. Among alternate technologies, the chemical enhanced oil recovery (EOR) technique has promising potential to recover residual oil from matured reservoirs being subjected to primary and secondary water flooding operations. Due to pertinent complex phenomena that often have a combinatorial role and influence, the implementation of chemical EOR schemes such as alkali/surfactant/polymer flooding and their combinations necessitates upon a fundamental understanding of the potential mechanisms and their influences upon one another and desired response variables. Addressing these issues, the book attempts to provide useful screening criteria, guidelines, and rules of thumb for the identification of process parametric sets (including reservoir characteristics) and response characteristics (such as IFT, adsorption etc.,) that favor alternate chemical EOR systems. Finally, the book highlights the relevance of nanofluid/nanoparticle for conventional and unconventional reservoirs and serves as a needful resource to understand the emerging oil recovery technology. Overall, the volume will be of greater relevance for practicing engineers and consultants that wish to accelerate on field applications of chemical and nano-fluid EOR systems. Further, to those budding engineers that wish to improvise upon their technical know-how, the book will serve as a much-needed repository.

This book aims at presenting, describing, and summarizing the latest advances in polymer flooding regarding the chemical synthesis of the EOR agents and the numerical simulation of compositional models in porous media, including a description of the possible applications of nanotechnology acting as a booster of traditional chemical EOR processes. A large part of the world economy depends nowadays on non-renewable energy sources, most of them of fossil origin. Though the search for and the development of newer, greener, and more sustainable sources have been going on for the last decades, humanity is still fossil-fuel dependent. Primary and secondary oil recovery techniques merely produce up to a half of the Original Oil In Place. Enhanced Oil Recovery (EOR) processes are aimed at further increasing this value. Among these, chemical EOR techniques (including polymer flooding) present a great potential in low- and medium-viscosity oilfields. • Describes recent advances in chemical enhanced oil recovery. • Contains detailed description of polymer flooding and nanotechnology as promising boosting tools for EOR. • Includes both experimental and theoretical studies. About the Authors Patrizio Raffa is Assistant Professor at the University of Groningen.

The application of nanotechnology in enhanced oil recovery (EOR) is emerging because nanoparticles have the potential to alter rock properties like wettability and fluid properties such as interfacial tension (IFT). In addition, a newly-proposed theory of the structural disjoining pressure (SDP) has become popular in the scientific community as well. However, a systematic literature review shows that ambiguity exists regarding which components in nanofluid play the role of changing wettability and interfacial tension (IFT). In addition, there are only a limited number of numerical and experimental studies to investigate the theory of the structural disjoining pressure (SDP), none of which can strictly confirm the theory. This motivates us to study these potential candidates of the mechanisms of nano-enhanced oil recovery (nano-EOR). We first conducted experiments using the contact angle goniometer to measure the contact angle and the interfacial tension (IFT) for various nanofluid compositions and the results showed that the addition of bare silica nanoparticles could reduce the contact angle. Specifically, a reduction in nanoparticle size and an increase in nanofluid concentration could further reduce the contact angle. However, bare nanoparticles did not change the interfacial tension (IFT). In order to investigate the theory of the structural disjoining pressure (SDP), we extended the model with a configuration that simulates the real case of the detachment of an oil droplet. The results showed that four conditions favor the spreading of the nanofluid on the substrate and the detachment of the oil droplet from the substrate to which it attached due to the structural disjoining pressure (SDP). These conditions include a high nanofluid concentration, a small nanoparticle size, a small contact angle of the nanofluid/oil/substrate system looking from the nanofluid phase, and a large oil droplet. Three imaging experiments were conducted using environmental scanning electron microscopy (ESEM) and dynamic fluid-film interferometry (DFI) to verify the theory of nanofluid spreading due to the structural disjoining pressure (SDP). ESEM imaging experiments showed the result of a single layer of nanoparticles but could not eliminate the effect of evaporation. Combining the ESEM images with the results from DFI in a liquid cell eliminated the evaporation effect and confirmed that nanoparticles are capable of spreading over the substrate in a thin film that is composed of one single layer of nanoparticles. Moreover, an experiment into the extension of the coffee ring effect showed the discovery of a new coffee ring pattern. Finally, we conducted a nanofluid flooding experiment using carbonate rocks. It was able to isolate the effect of the two confirmed mechanisms on the oil recovery rate at core-scale and tested the potential of nano-enhanced oil recovery (nano-EOR) at core-scale. We determined that an increase in oil recovery of 6% was due to the wettability alteration and another 6% increase in oil recovery was due to the mechanism of the structural disjoining pressure (SDP) for our low permeable carbonate core.

Nanotechnology has found widespread application in a diverse range of industries. Researchers are now investigating whether nanotechnology can be applied to enhance oil recovery. The goal of enhanced oil recovery is to manipulate the fluid-fluid properties (interfacial tension, viscosity), and fluid-rock properties (contact angle, relative permeability) to improve pore scale recovery efficiency. In this study, nanofluids were prepared and injected into micromodels to study their effectiveness on oil recovery. Silicon oxide and aluminum oxide nanoparticles were used. Nanofluid viscosity and interfacial tension between nanofluid and oil was measured and modeled. Response Surface Methodology (RSM) was used to investigate the effect of the factors and their interactions. Fluid characterization data shows that nanoparticles are effective in both interfacial tension reduction and viscosity enhancement. The results from the micromodel studies indicate that adding a small amount of nanoparticles to the brine can enhance oil recovery by approximately 10 % - 20 %.
