Well Test Design and Analysis (RES43)


    This course provides comprehensive information about testing methods, test design and interpretation. An overview of the technology application including the methodology of formation testing is provided. All aspects of test design are covered including downhole tools selection, surface facility considerations as well as dynamic modelling of the test sequence to ensure proper results for interpretation.
    The well test interpretation is performed by participants with commercial software using numerous examples of oil and gas well testing.

    Course Level: Foundation
    Instructor: Lukasz Ostrowski

    Designed for you, if you are...

    • A geologist, reservoir engineer, supervisor or manager involved in formation evaluation, reserve estimation, production technology and general reservoir engineering
    • An individual who is directly involved in well test operations
    • Someone who deals with service companies offering well testing
    • A professional with basic reservoir engineering knowledge

    How we build your confidence

    • A concise summary of applied testing methods is provided
    • Step-by-step introduction in well test analysis and methodology helps understand the functionality of specialised interpretation software
    • You learn to interpret the test with the newest methodology
    • Based on your knowledge of interpretation you are able to provide an appropriate test design
