Production Decline Analysis—Vertical and Horizontal Wells
Attendees of this course, offered in both 2-day and 3-day versions, will learn the Arps equations, the effects of layering and changing fluid properties on the Arps exponent, and comparing production characteristics of horizontal to vertical wells. Interpretation of performance curves to determine drive mechanisms, recovery efficiency, and effects of operations will also be covered.
- The utility of the quadratic equation
- The Fetkovich type curve approach
- The Blasingame type curve approach
- The Poe type curve approach for horizontal wells
The participant will become acquainted with the Arps, Fetkovich, Blasingame, and Poe decline curve analysis techniques. Assumptions and limitations of each analysis method are covered. Example and work problems are included to amplify salient points.
2 or 3 Days
Why You Should Attend
You will learn the meanings and limitations of the Arps exponential, hyperbolic, and harmonic equations.
Who Should Attend
Professionals who work in production data processing as it relates to reservoir description and dynamics.
Basic math skills are required. Some higher-level math is helpful but all problems can be solved with a spreadsheet.
