PVT Properties of Reservoir Fluids Training

Introduction

This Oil & Gas training course is designed to provide an understanding of the reservoir fluid properties and tools that are required for the estimation of hydrocarbon in place and reserves, designing the reservoir depletion process and the surface processing requirements, EOR method selection, identification and quantification of the marketable products and reservoir simulation studies. Following the completion of this course, all participants should be able to make decisions on field development planning with increased confidence.

This training course will feature:

• A review of the components of naturally occurring petroleum fluids
• The importance of phase diagrams and the relationships between the five reservoir fluids
• An outline of the most accurate methods for obtaining values of reservoir fluid properties from laboratory data and correlations
• Discussions on sampling procedures and quality control.
• An understanding of Cubic Equations of State (EOS) development and applications
• How to characterise reservoir fluids for EOS tuning

Objectives

By the end of the course, participants will be able to:

• Describe the phase behavior of reservoir fluids and production mechanisms using phase diagrams
• Explain and define saturated reservoirs, under-saturated reservoirs, bubble point pressure, gas and oil formation volume factors, solution and producing a gas-oil ratio
• Determine the properties of natural gas, oil, and water required for reservoir engineering calculations
• Use PVT reports determining oil and gas reserves
• Optimize separator operating conditions and perform separator calculations
• Explain reservoir fluids characterization and EOS Tuning procedures
• Make a decision on field development planning
• Describe the phase behavior of gas hydrates

Training Methodology

This is an interactive course. There will be open question and answer sessions, regular group exercises and activities, videos, case studies and presentations on best practice. Participants will have the opportunity to share with the facilitator and other participants on what works well and not so well for them, as well as work on issues from their own organizations.

Who Should Attend?

Personnel who should attend are:

• Petroleum and Reservoir Engineers who need to determine accurate values of the properties of reservoir gas, oil and water for use in engineering calculations and Simulation studies  
• Production and Operations Engineers who want to have an understanding of the way reservoir fluids behave, the reservoir depletion process and for designing surface processing requirements
• Petro-physicists, Geo-physicists, Geologists and Non – Engineers who work in teams with Petroleum and Reservoir Engineers to estimate hydrocarbon in place and reserves
• Analysts who are required to identify markets and product prices
• Managers who seek to derive greater decision making on-field development
