Introduction

RESERVOIR ENGINEERING


Petroleum reservoirs are broadly classified as oil or gas reservoirs.

These broad classifications are further subdivided depending on:

•The composition of the reservoir hydrocarbon mixture

•Initial reservoir pressure and temperature

•Pressure and temperature of the surface production

    The conditions under which these phases exist are a matter of considerable practical importance. The experimental or the mathematical determinations of these conditions are conveniently expressed in different types of diagrams commonly called phase diagrams. One such diagram is called the pressure temperature diagram.

These multicomponent pressure-temperature diagrams are essentially used to:

• Classify reservoirs

• Classify the naturally occurring hydrocarbon systems

• Describe the phase behavior of the reservoir fluid
