Well Test Interpretation

---

Disciplines: Production and Operations | Reservoir

Course Description

This course examines the fundamentals of well test interpretation for oil and gas wells. It covers the analysis of tests in vertical and horizontal wells: drillstem tests, wireline formation tests, flow/build-up tests, injection/fall-off tests interference/pulse test. Determination of permeability and damage, estimation of stabilized flow rates from short tests, detection of boundaries etc. The practice of well test interpretation will be emphasized along with the theory. To this end, Data Validation and the PPD (Primary Pressure Derivative) will be used to illustrate Wellbore Dynamics, and extricate these effects from the reservoir response. The concepts will be presented graphically (using a computer), thus keeping equations to a minimum. The practical aspects of the interpretation process will be highlighted.

Topics:

• What reservoir information can be derived from a well test
• Understand a well test analysis report
• Recognize that alternative interpretations may be possible
• Derive long term production forecast from a short test
• Recognize strengths and limitations of well test interpretation
