Advanced Well Test Analysis and Interpretation Training Course

Overview

Advanced Well Test Analysis and Interpretation Training Course is a one-week advanced course for reservoir, petroleum, production, well-test, and subsurface functions who leave with a Well Test Interpretation and Decision File. Participants apply pressure transient analysis, pressure derivative diagnostics, pressure and rate history conditioning, and well test model selection to drawdown, buildup, injection, and interference data. The course links data quality to permeability, skin, flow-regime, and boundary decisions. Agile Leaders Training Center presents advanced well test interpretation practice.

Who Should Attend

• Reservoir engineering functions responsible for pressure-transient interpretation and reservoir-property estimates
• Petroleum engineering functions responsible for test objectives, technical integration, and subsurface decisions
• Production technology functions responsible for rate histories, well performance, and operating evidence
• Well-test functions responsible for test design, gauge data, synchronization, and interpretation delivery
• Subsurface analysis functions responsible for diagnostic plots, model comparison, and uncertainty records
• Technical review functions responsible for challenging assumptions, evidence, and recommended actions

The course assumes participants already use reservoir-flow concepts, pressure and rate data, logarithmic plots, and engineering units, and it leaves out well-log interpretation, formation evaluation, casing design, stimulation design, and surface-test equipment operation.

Departments and Industries

The course supports departments and industries that use transient pressure response to evaluate wells and connected reservoir volumes.

• Oil and gas exploration and production
• Underground gas storage and carbon-storage operations
• Reservoir engineering and subsurface studies
• Production technology and well performance
• Well testing and petroleum engineering
• Technical assurance and asset development

FAQs

Who suits advanced well test analysis and interpretation training, and what does it assume?

Advanced well test training suits reservoir, petroleum, production, testing, subsurface, and review functions. It assumes working use of reservoir-flow concepts, pressure-rate data, logarithmic plots, and engineering calculations.

How does pressure transient well testing differ from well-log interpretation?

Pressure transient well testing evaluates dynamic pressure response after rate changes to infer connected flow behavior. Well-log interpretation evaluates measurements along the wellbore to characterize formations and fluids.

How do pressure derivative diagnostics support well test interpretation?

Pressure derivative diagnostics expose response shapes associated with storage, radial flow, fractures, dual porosity, and boundaries, helping analysts choose valid time windows and compare models.

How are permeability and skin evaluated in well test analysis?

Permeability and skin are evaluated from identified flow regimes, conditioned rate histories, pressure response, derivative behavior, and model assumptions, with parameter ranges checked against data quality and uncertainty.

Conclusion

Participants take back a Well Test Interpretation and Decision File linking objectives, conditioned data, diagnostic plots, model choices, parameter estimates, and uncertainty. It changes isolated plots into a traceable interpretation path. The file supports technical review, comparison of competing explanations, and reservoir decisions based on stated evidence and limitations.
