General Engineering, includes chapters on mathematics, fluid properties (fluid sampling techniques; properties and correlations of oil, gas, condensate, and water; hydrocarbon phase behavior and phase diagrams for hydrocarbon systems; the phase behavior of water/hydrocarbon systems; and the properties of waxes, asphaltenes, and crude oil emulsions), rock properties (bulk rock properties, permeability, relative permeability, and capillary pressure), the economic and regulatory environment, and the role of fossil energy in the 21st century energy mix. General Engineering, Volume I of the new Petroleum Engineering Handbook, has been designed to present material that is needed by all practicing petroleum engineers. It includes chapters on mathematics, properties fluids, rock properties, rock/fluid interactions, economics, the law, and the social context of fossil energy. The mathematics chapters of this volume are a major departure from previous editions. The mathematical tables presented in previous editions are now readily available using hand-held calculators or software on desktop computers.
