Description

Petroleum engineers are gaining better understanding of shale reservoirs but are still learning differences in calculating phase behavior to accurately determine distribution of shale fluids. Phase Behavior, Adsorption/Desorption Behavior and Interfacial Properties of Fluids 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 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 of shale reservoirs.

Key Features

  • Gain advanced understanding specifically for methods describing adsorption behavior of shale gas
  • Learn theories and calculations for measuring and computing with step-by-step instructions, including flash calculation for phase equilibrium
  • Advance in shale fluid behavior with well-structured experiments and flow charts

Readership

Petroleum engineers; reservoir engineers; researchers interested in shale oil and gas reservoirs
