Pressure, Volume, and Temperature (PVT) Analysis

Definition - What does Pressure, Volume, and Temperature (PVT) Analysis mean?

Pressure, Volume, and temperature (PVT) analysis is the determination of the characteristics and behavior of reservoir fluids under various conditions such as pressure, volumes, and temperature. The primary objectives of the study are:

  • To estimate the volume of crude oil and gas
  • To calculate the flow properties of reservoir fluids
  • To optimize the liquid recovery
  • To provide details about the pressure maintenance

The test is conducted by petroleum service provider to offer accurate data that helps in making qualitative engineering decisions.

Petropedia explains Pressure, Volume, and Temperature (PVT) Analysis

Pressure, Volume, and Temperature Analysis has made it easy to understand the complex behavior of reservoir fluids. Surface gas and oil samples are collected from the well sites to conduct the study. Then, the properties are determined by ISGS integrated instrument known as capillary viscometer system. It helps the engineers to maximize the hydrocarbon recovery at low cost. Using ideal gas law, PV=nRT, we can calculate the Pressure, Volume, and Temperature Analysis. However, the estimated values can also help in determining the reservoir pressure and compress-ability factor of the fluid.
