Enhanced Oil Recovery (EOR) in tight and shale oil reservoirs has been a difficult problem due to their high degree of heterogeneity and low to ultralow matrix permeability. Primary recovery factor from these reservoirs is generally lower than 10% of original oil in place (OOIP), which leads to the need for non-conventional technologies for EOR in these reservoirs. A thorough understanding of mass transfer processes in ultralow permeability porous media is required for successful designs of EOR projects in tight oil formations and shales. In this study, two advanced EOR methods that involve the reinjection of field gas into shale and tight oil reservoirs are investigated. In the first part of this dissertation, field gas huff-n-puff process as an EOR method for shales is systematically investigated using an optimal experimental design. For a better understanding of the mass transfer mechanisms in nano-sized pores, the effect of pressure program (i.e., pressure buildup and drawdown during a huff-n-puff cycle), reservoir and crude oil properties, solvent selection, and huff-n-puff cycle duration on oil recovery were investigated. The results show that thermodynamic phase behavior, molecular diffusion, and convection could be related to oil recovery factor, production rate, and produced oil composition, forming a conceptual model for natural gas huff-n-puff in shale reservoirs. The second part of this dissertation presents the investigation of a novel EOR method targeting water-sensitive tight formations with sub-10-mD permeability. Mobility control is crucial for high recovery efficiency in these tight oil reservoirs with high heterogeneity. Preferential flow in high permeability zones (or "thief zones") results in poor sweep efficiency. Conventional conformance control techniques such as polymer gels or even aqueous foam may not be suitable for water-sensitive, low-permeability reservoirs. Therefore, a novel concept of non-aqueous foam for improving field gas miscible displacement has been developed. This foam process involves the injection of a raw mixture of natural gas liquids (MNGLs) with non-condensable gas and a foaming agent, which could improve the sweep efficiency by the generation of non-aqueous foam and maximize the displacement efficiency due to the solubility between the crude oil and MNGLs. A specialty surfactant has been developed which could stabilize non-aqueous foam in MNGLs-crude oil mixture for in-situ foam generation. A pore-scale study of this foam process has been conducted using microfluidics to relate oil displacement to foaming mechanisms. The findings from this microscopic study have been validated using core flooding experiments on tight rocks. It can be concluded from both pore- and core-scale studies that the in-situ propagation of non-aqueous foam could be achieved for the first time and delay the injectant breakthrough, resulting in significant improvement of sweep efficiency

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.

"Micro-/nanofluidic model, as a potential powerful tool, has been used for decades for investigating fluid flow at pore-scale in energy field. It is still increasingly imperative nowadays to use different micromodels to direct observe pore-level fluid flow and analyze mechanisms of different enhanced oil recovery methods. In this work, three main tasks including three dimensional micromodels (1D,2D,3D) are proposed to fabricate and use for investigating different mechanisms of different enhanced oil recovery methods. For 1D capillary tube micromodel, we fabricate and use it to investigate the dynamics of a trapped oil droplet under seismic vibration. Seismic stimulation is a promising technology aimed to mobilize the entrapped non-wetting fluids in the subsurface. The applications include enhanced oil recovery or CO2 sequestration. For 2D micromodel, we fabricate to mimic unconventional dual-porosity shale-like tight porous media and investigate the fluid flow behavior under such conditions. Unconventional oil reservoirs have become significant sources of petroleum production and have even better potential in the future. Many shale oil systems consist of nanoscale pores and micro-scale fractures that are significantly smaller than those from conventional reservoirs. Therefore, it is increasingly important to investigate fluid flow behaviors in nanoscale channels. For 3D micromodel, we packed and sintered glass beads into quartz tubes to mimic 3D porous media. Because of difficulties for direct visualization, almost all the micromodels available are two-dimensional models which cannot represent real interconnected pore network of a real reservoir porous media. Thus, we build fully transparent 3D models to direct visualize and investigate the in-situ emulsification mechanism for nanogel flooding"--Abstract, page iv.

Unconventional reservoirs are usually complex and highly heterogeneous, such as shale, coal, and tight sandstone reservoirs. The strong physical and chemical interactions between fluids and pore surfaces lead to the inapplicability of conventional approaches for characterizing fluid flow in these low-porosity and ultralow-permeability reservoir systems. Therefore, new theories and techniques are urgently needed to characterize petrophysical properties, fluid transport, and their relationships at multiple scales for improving production efficiency from unconventional reservoirs. This book presents fundamental innovations gathered from 21 recent works on novel applications of new techniques and theories in unconventional reservoirs, covering the fields of petrophysical characterization, hydraulic fracturing, fluid transport physics, enhanced oil recovery, and geothermal energy. Clearly, the research covered in this book is helpful to understand and master the latest techniques and theories for unconventional reservoirs, which have important practical significance for the economic and effective development of unconventional oil and gas resources.

Most existing compositional reservoir simulators often model fractures using local grid refinement, unstructured-grid, or fine-grid models. Modeling different scales of fractures requires a large number of grid blocks to capture the heterogeneity of the formation. Using a large number of grid blocks presents computational challenges, even with todays powerful processors. An enhanced matrix permeability on the grid block that hosts short-scale fractures is commonly used to eliminate natural fractures and simplify the model. Additionally, several existing multi-porosity models may not be able to capture heterogeneity and flow behavior in different porosity domains. Sequential flow assumption is frequently made in their models. Flows between different porosity types are not fully coupled, and in some model, a simplified inter-porosity transmissibility function is used for any porosity pairs. The oil and gas reserves and flow of reservoir fluids are strongly dependent on phase behavior. Large capillary pressure values are encountered in tight formations such as tight-rocks and shales. The tiny pore throats in these formations result in large capillary pressure. The effect of capillary pressure in tight formations can significantly impact the fluid phase behaviors in the reservoir during production and enhanced oil recovery (EOR) processes. Not incorporating this effect into the simulation can result in an inaccurate estimation of ultimate recovery as well as inefficient design and implementation of EOR techniques. In spite of this, the effect of capillary pressure on phase behavior in tight reservoirs has not been well studied using compositional simulation, especially for hydraulically fractured reservoirs.In this research, a fully implicit, multi-mechanistic, fully coupled, triple-porosity, triple-permeability compositional model has been developed for unconventional reservoirs. The hydraulically fractured tight rock and shale reservoir is treated as a triple-porosity system consisting of matrix blocks, natural fractures (micro fractures), and hydraulic fractures (macro fractures). Small-scale fractures are handled by a dual-continuum model. An embedded discrete fracture model is used to effectively and efficiently capture the flow dynamics of hydraulic fractures at any orientations, honoring the complexity and heterogeneity of the fracture networks. The triple-porosity model enables us to assign reservoir properties corresponding to the porosity type. The flows in three porosity types are fully coupled without making the assumption of sequential flow. The inter-porosity fluid transfer honors the geometry of the intersecting porosity pair. The development of the proposed numerical model incorporates the effect of capillary pressure on phase behavior. The transport of hydrocarbon follows a multi-mechanistic flow mechanism that is driven by pressure and concentration fields. The simulator has been validated with analytical solutions and a commercial reservoir simulator for a single-porosity model and a dual-porosity, dual-permeability model, both with and without grid refinement. With the proposed model, we can accurately capture major physics of transport phenomena that have been done to date and have the most realistic modeling of fluid flow in hydraulically fractured tight rock and shale reservoirs. The simulator is used in parametric studies to investigate the production performance from hydraulically fractured reservoirs under different modeling techniques and the effect of capillary pressure on phase behavior on reserves and ultimate recovery. The simulator is used to study the impact of inter-porosity transport on the recovery and fluid transport and phase behavior in hydraulically fractured tight rocks and shale formations under high capillary pressure. The outcomes of this project are an improved understanding of phase behavior and fluid flow in hydraulically fractured shale and tight rocks and an increased accuracy of the production prediction and ultimate recovery.
