Thisbook is dedicated to my son Alhaj U. Chaudhry. I am grateful to my parents for providing me with education, inspiration, and confidence. I am also indebted to my ex-wife (Nuraini Smith) who provided the encouragement, fortitude, and extraordinary understanding, which enabled me to steal many hours from my family while writing this book.

Foreword

Although elements of oil well testing methodshave been practical almost since oil reservoirs were first recognized, the concept of oil well testing techniques took form only within the past three decades. Many individual monographs and at least one manual on the subject have been published in the open literature, and it is probable that proprietary presentations of oil well testing concepts are to be found within the internal libraries ofsome oil-producing companies. In the present volume, the author presents a treatment of the subject to be published in book form. The roots of oil well testing are to be found in reservoir engineering taken in its broadest sense as the technology that deals with the well/reservoir behavior through the measuring and analysis of drill-stem tests, flow, and transient pressure responses in unfracturedand fractured gas wells. The concepts related to oil well test data acquisition and interpretation are presented from a practical viewpoint. These concepts are emphasized throughout the book by means of examples and field case studies. In Oil Well Testing Handbook, the author has presented a comprehensive study of the measuring and analysis of flow and transient pressure responses in oil wells. Thebasic principles are reviewed, and the applicability and limitations of the various testing techniques are critically discussed and illustrated with actual field examples. The material is presented in a form that will allow engineers directly involved in well behavior, pressure build-up, and flow testing to re-educate themselves in the subject. At the same time, with its up-to-data review of theliterature and extensive bibliography, the book will serve as a useful guide and reference to engineers directly engaged in well pressure behavior work. The author has accomplished the intended objectives of the book in a thorough and excellent manner. The author has illustrated field application examples andfieldcase studies to describe the type of wells and reservoir behavior encountered in...
