Intro to Reservoir Fluid Behavior, Production Trends and Analysis

The need for good, representative reservoir fluid samples is critical to the effective design and operation of any development project. The decision to build and deploy production facilities exposes producers up to several billion dollars of investment risk, and a solid understanding of formation fluids right after discovery plays an essential part in mitigating that risk. Whether obtaining Gulf of Mexico Wireline Formation Test tool samples from 20,000 feet or surface separator samples from Terrebonne Parish La., fluid analysis provides the ammunition needed for more efficient use of assets.

Many times, the only exposure that asset members get to fluids is hearing the reservoir engineer “talk” about getting “PVT samples”.  This 45-minute presentation will cover the basics of reservoir fluid behavior, sampling and analysis.  The “big picture” may include many investigations such as determining drive mechanisms, formation rock properties, geophysical properties as well as formation fluid properties.  Fluids analysis provides data critical to predicting well and reservoir performance, surface and subsea facilities design, and fluid quality assessment for determining market price.

The presentation will provide the ammo needed to answer the question “do I need measured PVT data and what happens if I don’t get it”.

Outline of Topics Covered:

  • Introduction to PVT analysis?Why perform it? What data does it provide? Who uses it?
    • Reservoir Engineering 101
    • Phase Behavior and basic fluid properties
  • Overview of Sampling Sources
    • Surface vs Subsurface
  • Blueprint for Complete Fluids Program
    • Chemistry, Component Analyses, chemistry
    • Physical Properties, ‘PVT’ Experiments, Flow Assurance
    • Surface Recoveries
    • Mathematics, Modeling etc.
  • Bringing it all together – The Real Value of Fluids Analysis
    • How is the data used?
    • Bottomline: Increasing RRR and Decreasing F&D!
    • What happens if I don’t have PVT data?
