Über dieses Buch

This book provides a succinct overview on the application of rate and pressure transient analysis in unconventional petroleum reservoirs. It begins by introducing unconventional reservoirs, including production challenges, and continues to explore the potential benefits of rate and pressure analysis methods. Rate transient analysis (RTA) and pressure transient analysis (PTA) are techniques for evaluating petroleum reservoir properties such as permeability, original hydrocarbon in-place, and hydrocarbon recovery using dynamic data. The brief introduces, describes and classifies both techniques, focusing on the application to shale and tight reservoirs. Authors have used illustrations, schematic views, and mathematical formulations and code programs to clearly explain application of RTA and PTA in complex petroleum systems. This brief is of an interest to academics, reservoir engineers and graduate students.

Chapter 1. Unconventional Oil and Gas Reservoirs

Abstract
Unconventional resources or unconventional reservoirs (UR) refer to a category of underground hydrocarbon deposits which are different in operations and methods of recovery compared to conventional reservoirs.

Chapter 2. Unconventional Reservoir Engineering

Abstract
The most fundamental concept in reservoir engineering is the fluid flow. Considering reservoirs as porous materials (rock) that are saturated with hydrocarbons (fluid), flow in the reservoir can be described through general understanding of dynamics of hydrocarbons flow in porous media.

Chapter 3. Pressure Transient Analysis

Abstract
Pre-frac tests are short-term well-testing techniques that are used in unconventional reservoirs (URs) to obtain reservoir properties and a means of data collection via pressure transient analysis (PTA). These PTA techniques have much shorter test duration compared to build up and long-term draw-down tests which are mostly run for at least several weeks.

Chapter 4. Rate Transient Analysis

Abstract
Naturally, by producing from the reservoirs due to reduction in reservoir average pressure and the resulting change in production mechanisms, the rate of production will experience a decreasing trend over time. This declining trend in production rate is not that significant in the development phase of the fields when new wells are drilled and come into production. However, as production continues, this declining trend in the production rate from the wells become inevitable.
