Production Decline Analysis—Vertical and Horizontal Wells
Attendees of this course will learn the the origin and utility of the Arps and quadratic equations as well as how to adapt the Fetkovich, Blasingame, et.al., and Poe type curve approach to analyze production decline curves. Example problems will be reviewed for all cases.
- Effects of layering, changing fluid properties and introduction of two phase flow on performance
- Expected differences between vertical, fractured and horizontal well performance.
- Normalizing time and production rate to obtain a more cohesive performance picture.
- Developing methods to estimate reserves when transient conditions exist.
- The utility of studying multiple plots when analyzing well behavior is discussed and illustrated.
2 or 3 Days
Attendees will become acquainted with the basics of commonly available computer analysis methods. Assumptions and limitations of each method are covered.
Who Should Attend
Professionals who work in production data processing and analysis as it relates to forecasting, reserves estimates and reservoir description.
1.6 or 2.4 CEUs (Continuing Education Units) awarded for this 2 or 3-day course.
Basic math skills are required. Some higher-level math is helpful but all problems can be solved with a spreadsheet.
