About the Course

This course is designed to provide delegates with the principles of dynamic well testing relating to downhole, sub-sea and surface equipment. It also gives an insight into well test planning, execution, QC and data analysis. The students will get an understanding of how hydrocarbon-bearing reservoirs are evaluated, i.e. formation properties, wellbore damage, reservoir boundaries, and heterogeneities - in terms of wellbore pressures and flowrates.

Duration

5 days

Who Should Attend

Geologists; Drilling Engineers; Reservoir Engineers; Petroleum and Production Engineers; Development, Asset and Project Managers.

You Will Learn

• Basic Reservoir Understanding and Reservoir concepts - porosity and permeability - Reservoir drive mechanisms
• VOI (Value of Information) - Reasons for performing well tests
• Types of Test; Oil or Gas, Cased hole, Barefoot – Openhole, Closed Chamber, Isochronal, Multi-Rate - Deciding type of Test
• Understanding of Requirements
• Surface well test equipment description and operation - Phase tester versus Separator - Burner heads - heat radiation
• Downhole and sub-sea well test equipment description and operation
• Well test planning - Conducting a well test - Fluid flow rate calculations - Perforation design - Sand production - Deep water considerations
• Preparation of a complete testing program - Rates required/expected - sizing of equipment and flow lines - suitability of rig equipment - Sand, Hydrates, wax, water etc. to be considered
• Safety on surface - pressure testing ESD - function testing drills etc.
• Electric line testing - Generic Downhole Equipment ( MDT , RCI, RDT)
• Hazards - Nitrogen Handling - H2S / CO2 – Hydrates – Sand, etc.
• Selection and position of gauges; Surface read out systems versus memory only tests.
• QC of test data – surface data and gauge data
• On-site analysis
• Interpretation of test data.
