About
Decline curve analysis has been called the most commonly used and misused technique for forecasting future production and remaining reserves. This course will give the learner a better understanding of how fundamental reservoir properties and drive mechanisms affect the shape of the production decline curve and how to avoid many of the mistakes commonly found in decline curve forecasts. The course also examines the use of modern production decline type-curves to evaluate reservoir properties and predict future performance. One personal computer is provided, at additional cost, for each two participants. This course covers both conventional and unconventional reservoirs.

Target Audience
You Will Learn
Participants will learn how to:
- Use the exponential, hyperbolic and harmonic decline curve equations
- See the relationships between reservoir recovery mechanisms and decline curve types
- Identify and understand how the transient flow period can lead to an overestimation of reserves
- Use multiple methods to avoid overestimating reserves
- Recognize reservoir performance characteristics based on actual field examples
- See the impact of reservoir heterogeneities such as faulting, permeability variance, and layering
- Account for changing operating conditions
- Perform analysis on a multi-well basis without introducing common errors
- Use alternative methods including diagnostic performance plots (e.g., log WOR vs. Np, Stagg's, P/Z vs. Gp, etc.) for rate and reserves analysis
- Use advanced decline curve and production data analysis for reservoir characterization: flow regime, hydrocarbons-in-place, permeability, skin, drainage area, fracture properties, etc.
