The course emphasizes the practical application of well test theory to the solution of real well testing problems from design through interpretation for oil, gas and water injection wells. Participants will be introduced to a systematic approach to well test analysis and will apply it using modern well test analysis software. Numerous data sets with non-ideal behavior will be reviewed and analyzed to allow participants to gain experience with real world problems. Participants will be able to apply their newly acquired skills in their job assignments immediately upon course completion.
After successfully completing this course, delegates should be able to:
- Design well tests and specify equipment requirements
- Set up and analyze well tests for oil and gas wells using traditional and modern well testing analysis techniques
- Perform QC analysis of pressure data; identify and discard “bad” data
- Identify various wellbore and reservoir characteristics and choose the appropriate model for analysis
Duration: 5 days
Types of well tests • Behavior of simple, ideal systems • Wellbore Skin • Wellbore storage mechanisms • Semilog analysis • Type curves • Hydraulically fractured wells
- Superposition and horner plots • Average reservoir pressure • Derivative curves • Interference and pulse tests • Data preparation and QC procedures • Well test design
- Pattern recognition and model selection • Complex reservoir models • Multi-layer reservoirs • Horizontal wells • Back pressure tests for gas wells • Reality checks
Engineers and geoscientists who want to understand well testing principles and interpretation techniques to design, analyze, report, evaluate results or intelligently participate in the well testing process. Previous experience in well testing, production operations and reservoir engineering is helpful but is not required.
