Unconventional Reservoir Rate-Transient Analysis

Unconventional Reservoir Rate-Transient Analysis: Volume One, Fundamentals, Analysis Methods and Workflow provides a comprehensive review of RTA methods, helping petroleum engineers and geoscientists understand how to confidently apply RTA to tight reservoirs exhibiting single-phase flow of oil and gas. The book provides practitioners with an overview of the basic concepts used in RTA, including flow-regime identification and application of straight-line analysis, type-curve analysis, and model history-matching approaches that are applicable to low-complexity, tight reservoirs exhibiting single-phase flow of oil and gas. Workflow steps are discussed and illustrated in detail for hydraulically fractured vertical wells and multi-fractured horizontal wells.

Supported by many real-world field examples, this comprehensive resource supplies today’s petroleum engineers and geoscientists with an overview of RTA methods as applied to tight reservoirs. A companion text, Unconventional Reservoir Rate-Transient Analysis: Volume Two, Application to Complex Reservoirs, Exploration and Development bridges a critical knowledge gap to help practicing petroleum engineers and geoscientists understand how RTA methods can be adopted and applied to today’s unconventional reservoirs.

• Reviews key concepts and analysis methods used in modern rate-transient analysis (RTA) as applied to low-permeability ("tight") oil and gas reservoirs
• Provides a workflow for confident derivation of reservoir/hydraulic fracture properties and hydrocarbon-in-place estimates for wells completed in unconventional reservoirs
• Includes detailed discussions and illustrations of each step of the workflow using field examples
