Introduction

The conventional and modern well test interpretation methods are an important tool in the petroleum engineer's toolkit. Used in the exploration and discovery phase of a field, they are performed to determine the quality of a well or to permit estimation of producing rates at different producing pressures. However, once a field enters the middle and later development phase, the reservoir flow environment grows increasingly complex and conventional or modern methods do not satisfy the needs of old field development and evaluation.

About the Book

Based on over 10 years of field and research experience, Streamline Numerical Well Test Interpretation Theory and Method provides an effective method for the determination of residual oil distribution for the middle and mature phases of a field. One of the most advanced books available, the author explains the development history of well test theory, analyzes the limitations of modern well test interpretation methods, and proposes the concept and framework of numerical well test.

Content Overview

This is quickly followed by an introduction of basic principles and solution procedures of streamline numerical simulation theory and method. The book then systematically applies streamline numerical well test interpretation models to a multitude of reservoir types, ranging from single layer reservoir to multi-layer reservoirs. The book presents a multi-parameter streamline numerical well test automatic match interpretation method based on a double-population genetic algorithm, which lays the foundation for fast automatic matching of numerical well tests.

Software and Applications

The book introduces streamline numerical well test interpretation software with independent intellectual property rights, programmed based on the above theoretical studies. It covers:

• Single and multi-layer sandstone water flooding reservoirs
• Multi-layer sandstone chemical flooding models and components
• Application of streamline numerical well test and software
• Application of programmed software to 177 wells
• Quick calculation of pressure, saturation, and streamline distribution
• All kinds of numerical well test interpretation models
• Avoidance of disadvantages of conventional and numerical well test interpretation methods
• Complete tutorial on streamline numerical well test interpretation software
