Fluid Phase Behavior for Conventional and Unconventional Oil and Gas Reservoirs

Book Description

Fluid Phase Behavior for Conventional and Unconventional Oil and Gas Reservoirs delivers information on the role of PVT (pressure-volume-temperature) tests/data in various aspects, in particular reserve estimation, reservoir modeling, flow assurance, and enhanced oil recovery for both conventional and unconventional reservoirs.

This must-have reference also prepares engineers on the importance of PVT tests, how to evaluate the data, develop an effective management plan for flow assurance, and gain perspective of flow characterization, with a particular focus on shale oil, shale gas, gas hydrates, and tight oil making.

This book is a critical resource for today’s reservoir engineer, helping them effectively manage and maximize a company’s oil and gas reservoir assets.

  • Provides tactics on reservoir phase behavior and dynamics with new information on shale oil and gas hydrates
  • Helps readers Improve on the effect of salt concentration and application to C02-Acid Gas Disposal with content on water-hydrocarbon systems
  • Provides practical experience with PVT and tuning of EOS with additional online excel spreadsheet examples
