Determination Of Flowing Bottom-hole Pressure From Well-head Data

CHAPTER1 1.0 INTRODUCTION 1.1 BACKGRAND OF STUDY      Interpretation of data from Well test analysis have been based on the implicit assumption that the reservoir is a homogeneous single layer. However, the real petroleum reservoir, is a composition of layers with unique interlayer characteristics. The individual layers are usually separated from each other by an interface which could be either permeable or impermeable. Pressure behavior in this kind of vertically heterogeneous system is not necessarily like that of a single layered system and seldom reveals more than the average properties of…
