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 Duration: 4 days
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
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
Reasons for well testing
Methodology of well testing - Initial perturbation - Constant pressure vs. constant rate condition - How to deal with wellbore storage - Types of well test sequences
Hardware options - How the well test data is gathered - Testing while drilling - Testing after completion of drilling - Traditional versus wireline formation testing - Surface equipment and safety in well testing operations
Theory behind interpretation - Historical overview from straight line to deconvolution - Flow geometries and regimes - Unified approach for well test interpretation
Interpretation approach - Superposition concept - Diagnosing near wellbore conditions, reservoir behaviour and boundaries - Deconvolution - Dealing with limited reservoirs - Predicting the well behaviour
