How do you define phase behavior?
Phase behavior describes the complex interaction between physically distinct, separable portions of matter called phases that are in contact with each other. Typical phases are solids, liquids and vapors. Phase behavior plays a vital role in many petroleum applications, such as: Enhanced oil recovery.
Why is phase behavior important reservoir engineering?
Phase Behavior has many implications in natural gas and petroleum engineering. Pressure, volume, temperature (PVT) relations are required in simulating reservoirs, evaluating reserves, forecasting production, designing production facilities and designing gathering and transportation systems.
Why do we need to study reservoir fluid thermodynamics?
o The thermodynamic characterization of reservoir and injected fluids allows us to perform rigorous analyses of the oil recovery processes. o A continuous program that will reveal important factors that are still unknown or not well understood and affecting the efficiency of oil recovery.
What is petroleum phase diagram?
A phase is the portion of a system that is homogeneous, is bounded by a surface, and is physically seperable from other phases. Equilibrium phase diagrams offer convenient representations of the ranges of temperature, pressure, and composition within which various combinations of phases coexist.
What is the role of components in a phase diagram?
Overview. Common components of a phase diagram are lines of equilibrium or phase boundaries, which refer to lines that mark conditions under which multiple phases can coexist at equilibrium. Phase transitions occur along lines of equilibrium. Triple points mark conditions at which three different phases can coexist.
What are the factors that change the properties of reservoir fluids?
Petroleum reservoirs may contain any of the three fluid phases—water (brine), oil, or gas. The initial distribution of phases depends on depth, temperature, pressure, composition, historical migration, type of geological trap, and reservoir heterogeneity (that is, varying rock properties).
