Full Life Cycle Fluid Evaluation - Downhole to Laboratory

Hydrocarbon accumulations in subterranean porous media may display vertical, as well as areal variations of properties. During production, these fluids also go through phase change phenomena as a result of changes in temperature and pressure conditions.  These changes can occur at any location in the production circuit including reservoirs, near-wellbore formation, production tubulars, and surface flow lines. Understanding the variations of the fluid properties can impact well placement, production, and reservoir management decisions.

In this five-day workshop, participants will be exposed to various technologies that are currently used in the industry to characterize reservoir fluids in-situ, including heavy fractions like asphaltenes and methodologies, to capture a representative sample. The course will demonstrate the importance of sample handling in the field, as well as in the laboratory. Furthermore, the participants will be exposed to various laboratory measurement techniques and procedures to define various properties. Participants will also get hands on experience in developing mathematical models using equations-of-states (EOS) and the fluid PVT properties for applications in reservoir simulations, production modeling, upgrading, and surface processing. Depending on the location of the course, participants may have an opportunity to visit a PVT laboratory.
