Overview
Practical learning for workplace transfer.
This in-depth technical course develops directly applicable capability in Well Testing and Pressure Transient Analysis. It connects Test Objectives, Design, and Data Acquisition, Pressure Transient Analysis Foundations, Flow-Regime and Reservoir-Model Diagnosis to the calculations, diagnostics, and engineering decisions encountered in field operations. The five modules progress toward Pressure-Transient Interpretation Workshop using course-specific data, plots, calculations, and technical work products.
Objectives
- Analyze test objectives, design, and data acquisition, including select drawdown, buildup, injectivity, falloff, interference, pulse, and drillstem test sequences.
- Build pressure transient analysis foundations, including apply diffusivity, superposition, semilog straight-line, horner, mdh, and pressure-derivative concepts.
- Diagnose flow-regime and reservoir-model diagnosis, including recognize radial, linear, bilinear, spherical, and pseudosteady-state flow signatures.
- Evaluate gas, injection, and complex test interpretation, including use gas pseudopressure, pseudotime, deliverability, turbulence, and rate-dependent skin corrections.
- Complete pressure-transient interpretation workshop, including quality-check pressure, rate, temperature, depth, event, and synchronization data before interpretation.
Target audience
- Drilling, reservoir, production, and well engineers
- Petroleum engineers, geoscientists, and technical specialists
- Operations, subsurface, and field-development team members
- Technical assurance, studies, and asset-team professionals
- Experienced personnel moving into specialist petroleum-engineering responsibilities

Program outline
Outline points are grouped in one designed block instead of being treated as separate module cards.
Module 1: Test Objectives, Design, and Data Acquisition
Select drawdown, buildup, injectivity, falloff, interference, pulse, and drillstem test sequences
Specify gauge range, accuracy, resolution, depth, redundancy, sampling frequency, and clock synchronization
Plan rates and shut-in duration around wellbore storage, stabilization, boundary investigation, and operational limits
Module 2: Pressure Transient Analysis Foundations
Apply diffusivity, superposition, semilog straight-line, Horner, MDH, and pressure-derivative concepts
Separate wellbore storage, skin, radial flow, and late-time behavior on log-log diagnostic plots
Estimate permeability-thickness, skin, pressure, flow capacity, productivity, and radius of investigation
Module 3: Flow-Regime and Reservoir-Model Diagnosis
Recognize radial, linear, bilinear, spherical, and pseudosteady-state flow signatures
Diagnose sealing faults, constant-pressure boundaries, channels, compartments, and composite reservoirs
Interpret fractured, horizontal, partially penetrating, multilayer, and naturally fractured well responses
Module 4: Gas, Injection, and Complex Test Interpretation
Use gas pseudopressure, pseudotime, deliverability, turbulence, and rate-dependent skin corrections
Interpret injection and falloff tests with changing mobility, thermal effects, and pressure-dependent properties
Apply deconvolution, rate history, production interference, and data-quality checks to non-ideal tests
Module 5: Pressure-Transient Interpretation Workshop
Quality-check pressure, rate, temperature, depth, event, and synchronization data before interpretation
Construct diagnostic plots, select a reservoir model, and match early-, middle-, and late-time responses
Report reservoir parameters, model alternatives, uncertainty, operational implications, and recommended follow-up
