Contemporary Topics for Liquid-Rich-Shale (LRS) Reservoirs: Fluid Sampling, Characterization and Gas-Injection EOR

Reservoir Descriptions and Dynamics Production and Operations


This course begins with reservoir fluid properties starting with the most fundamental definitions and then expanding to how fluid properties are measured and reported. Common problems, encountered in sampling and characterization, are discussed by using multiple field examples. A thorough presentation of methods to achieve the best characterization for bubble-point fluids and retrograde gases is included; recent developments (2017) are elucidated. The roles of confinement and fracture intensity on apparent phase behavior are also discussed. Finally, the science of Lean-Gas cycling for EOR in shales is introduced and analyzed.


To explain fluid sampling and characterization challenges in liquid-rich-shale (LRS) reservoirs and to offer best practices in order to minimize errors for the most challenging produced fluids. To explore the science of Lean-Gas cycling EOR by discussing three mechanisms of EOR in the context of two pressure regimes: Matrix and Fractures.
