This course provides structured information about testing methods, data acquisition and related downhole tools and surface equipment used in the hazardous business of well testing. It includes a comprehensive overview of the technology application, details of the hardware with its benefits and limitations, all important operational aspects of oil and gas well testing as well as safety procedures and recommended practices. A dedicated module covers the theory and practice of well test analysis and interpretation as well as test design.
Optional: Practical exercises on interpretation software (licence fees are not included in course fee)
Course Structure: 28 modules of 1 hour each, delivered over 4 days Each day will consist of 7 modules of 1 hour length with multiple breaks and a 1 hour lunch break.
Course Level: Foundation Duration: 4 days Instructor: Lukasz Ostrowski

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
Downhole hardware options - how the well test data is gathered - Testing while drilling - Testing after completion of drilling - Traditional versus wireline formation testing
Surface testing equipment - Onshore and offshore testing operations - Pressure gauges - Gas, oil and water flow measurement - Sub-sea equipment
Well testing operations - Equipment checks - Well control - Perforating - Fluids behaviour and sampling operations - Stimulation in well testing
Safety in well testing operations
Interpretation approach - Superposition concept - Diagnosing near wellbore conditions, reservoir behaviour and boundaries - Deconvolution - Dealing with limited reservoirs - Predicting the well behaviour
