Well Test Analysis
Objectives:
Basic and applied well test analysis and pressure transient concepts are the focus of this course practical field process methods to evaluate new wells and manage existing reservoirs are presented. The course is designed for those who have limited experience in well test analysis and for others who want to improve their capabilities of using pressure transient analysis to evaluate reservoir quality and completion efficiency.
Course outlines:
• Basic test analysis:conventional semilog methods, type curves,waterflow effects, linear flow-well-bore area effects, evaluation of completion efficiency, overall skin factor, cross-sectional area to flow of welbore, sandface damage, flow efficiency, condition ration
 
• Gas well behavior:pressure , pressure squared, and real gas potential analysis methods: real gas pseudotime analysis: multiphase analysis
 
• Boundary effects:closed outer boundary , constant pressure outer boundary, faults, drainage boundaries
 
• Test design: sure , bottomhole pressure, bottomhole recording, surface readout, required accuracy and resolution; measuring flow-liquids and gases
 
• Conducting the test, including pitfalls
 
• Applications: buildup, falloff, drillstem, potential, interference-conventional and pulse, and constant pressure testing
 
• Rate prediction: flow capacity from overall skin factor basis, rate at constant pressure, usefulness and limitations, flow capacity from wellbore area and sandface skin factor basis, application of linear flow dominated cases
