The main focus of this book is to show the challenges specific to shale hydrocarbon recovery and the practices to overcome these challenges. This book starts with an overview to the technological evolution that led to successful production of shale plays, and the implications of the shale being a source rock for its hydrocarbon recovery. The second chapter presents the operations of well drilling, hydraulic fracturing, and monitoring activities. Chapter 3 provides an overview of the available methods for reserve estimation of shale resources followed by comprehensive coverage of decline curve analysis (DCA). In a departure from the mostly empirical rate-time DCA methods covered in Chapter 3, advanced rate-time-pressure analysis – often referred to as rate transient analysis (RTA) - methods are presented in Chapter 4. Chapter 4 ends with discussing the complications of fluid flow in shale reservoirs and the required modeling improvements.

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

This research focuses on: (1) explaining the observed increase in well ow rate resulting from long shut-in periods in some production wells, and (2) investigating whether water- ooding can improve hydrocarbon recovery in the greater Bakken formations. Relevant is-sues include pore size and distribution, pore architecture, hydrocarbon composition, salinity, wettability, capillarity, osmotic pressure, and geomechanical alterations of pore connectivity because of water ooding. Water ooding may induce an increase in the shear stress followed by rock failure because of an increase in pore pressure and a decrease in temperature. Two numerical models were developed to: (1) investigate the e ect of gravity, capillarity and osmoticity on phase re-distribution during well shut-in and (2) determine the e ect of induced stress generated by water ooding on creation of microfractures to stimulate reservoir performance."

Shale oil contributes more than 60% to the US oil production. Shale oil production has been feasible because of technological development for horizontal wells with multistage hydraulic fracturing. However, after primary production, more than 90% of the oil is left behind in shale oil reservoirs due to ultra-low permeability. For an average well the oil production rates fall sharply in the first year because of the extremely low permeability, micro-fracture closure, and large flow resistance at the matrix-fracture interface. To sustain oil production from shale oil, it is essential to develop enhanced oil recovery (EOR) techniques for unconventional reservoirs. In this dissertation, lab experiments were conducted to investigate the effect of chemical treatment, gas huff-n-puff, and/or both on EOR in shale oil reservoirs. Surfactant treatment on shale was studied. Static adsorption experiments were performed to investigate the adsorption behavior of surfactant on shale samples. An additive model was built to estimate the adsorption capacity given the mineral composition and TOC of shale samples. A series of surfactant screening process, including aqueous stability tests, contact angle measurements, interfacial tension measurements, and spontaneous imbibition experiments, was used to compare the performance of surfactants at reservoir conditions. Surfactant blends were compared with single surfactants, and the surfactant blends showed improved oil recovery compared to most single surfactants. Chemical blends showed good EOR potential in Eagle Ford formation, and the effects of solvents in chemical blends were investigated via spontaneous imbibition process. Chemical blends with solvents showed improved recovery compared to the brine-only controlled case, and the Green Solvent showed the most promising results among the five solvents tested. Cyclic gas injection was investigated with CO2 and hydrocarbon gases. CO2 huffn-puff showed about 40% oil recovery, and it was observed that the huff pressure to which the cores were pressurized with CO2 did not affect the oil recovery significantly as long as the pressure was high enough. A combination of chemical blend with CO2 was more effective compared to pure CO2 huff-n-puff (40% → 64%). The hydrocarbon gas (60% C1 + 35% C2 + 5% C3) showed a similar effectiveness as CO2, which can be used to replace CO2 depending on availability and cost. Also, a numerical simulation model was built to investigate the key parameters in the gas huff-n-puff qualitatively. The learning from these simulations can be used for future experimental design
