Advanced Well Testing and Interpretation (RES37)

    Description

    This course provides comprehensive information about testing technology, methodology, test design and interpretation on an advanced level. An overview of well test application is provided including a comprehensive overview of wireline formation testing. 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 on numerous field examples using the two alternative commercial software packages.

    Course Level: Skill
    Instructor: Lukasz Ostrowski

    Designed for you, if you are...

    • A professional who is directly involved in pressure transient interpretation or dealing with service companies offering well testing
    • A geologist, reservoir engineer, supervisor or manager who is involved in formation evaluation, reserve estimation and general reservoir engineering
    • A professional with basic understanding of well testing and interpretation

    Practical experience in well testing is beneficial but not mandatory.

    How we build your confidence

    • Numerous examples and exercises to develop your interpretation skills
    • Exercises are based on both simulated and real field examples
    • Significant time is spent on test design and prediction runs
    • Before you use commercial interpretation programs, you will learn the foundation of analysis applying Excel

    The benefits from attending

    By the end of the course you will feel confident to:

    • Select the appropriate test methodology
    • Select the required downhole and surface equipment
    • Design the test sequence
    • Interpret the test data utilising the newest methodology including deconvolution
    • Predict the well production behaviour
