Confined Fluid Phase Behavior and CO2 Sequestration in Shale Reservoirs delivers the calculation components to understand pore structure and absorption capacity involving unconventional reservoirs. Packed with experimental procedures, step-by-step instructions, and published data, the reference explains measurements for capillary pressure models, absorption behavior in double nano-pore systems, and the modeling of interfacial tension in C02/CH4/brine systems. Rounding out with conclusions and additional literature, this reference gives petroleum engineers and researchers the knowledge to maximize productivity in shale reservoirs.
- Helps readers gain advanced understanding of methods of adsorption behavior in shale gas
- Presents theories and calculations for measuring and computing by providing step-by-step instructions, including flash calculation for phase equilibrium
- Includes advances in shale fluid behavior, along with well-structured experiments and flow charts
