Fundamentals Petroluem

Naturally occurring hydrocarbon systems found in petroleum reservoirs

are mixtures of organic compounds that exhibit multiphase behavior

over wide ranges of pressures and temperatures. These hydrocarbon

accumulations may occur in the gaseous state, the liquid state, the solid

state, or in various combinations of gas, liquid, and solid.

These differences in phase behavior, coupled with the physical properties

of reservoir rock that determine the relative ease with which gas and

liquid are transmitted or retained, result in many diverse types of hydrocarbon

reservoirs with complex behaviors. Frequently, petroleum engineers

have the task to study the behavior and characteristics of a petroleum

reservoir and to determine the course of future development and

production that would maximize the profit.

The objective of this chapter is to review the basic principles of reservoir

fluid phase behavior and illustrate the use of phase diagrams in classifying

types of reservoirs and the native hydrocarbon systems.

CLASSIFICATION OF RESERVOIRS

AND RESERVOIR FLUIDS

Petroleum reservoirs are broadly classified as oil or gas reservoirs.

These broad classifications are further subdivided depending on:
