Offering a well-balanced presentation of fundamental concepts and practical aspects, this book describes various rock and fluid properties using mathematical expressions and various laboratory measurement techniques to illustrate the correlations and influence between the various properties and relate them to reservoir and petroleum engineering. The book includes references from petroleum and other engineering literature, discussions on methods for tackling problems encountered in real life situations, extensive graphical illustrations, and practice problems on practical applications. It is ideal for undergraduate and graduate students and a valuable reference for chemical engineers.
