Length: 1 day, 8:30 am - 4:30 pm
Who Should Attend: Engineers and technologists involved in the exploitation, production and evaluation of tight and unconventional reservoirs.
Prerequisites: At least some prior experience with the Harmony environment is expected. An ideal prerequisite is the IHS Harmony Forecast™ course. Alternatively, attending the IHS Harmony™ - Getting Started course would be satisfactory.
Students should have an understanding of basic engineering principles including:
- Well attributes and reservoir properties
- Production data quality
- Pressure calculations in pipelines and wellbores
- Conventional reservoir analysis
Tuition: $1000.00 CAD/USD. All Canadian courses are subject to GST.
Cancellation Policy: To cancel without penalty, please give notice seven calendar days prior to the start of the course. Without prior notice, you will be charged full tuition.
*Class hours can be used towards APEGA professional development credits.
An introduction to well performance analysis
- Review the fundamentals of rate transient analysis
- Learn the modern production analysis methodology
- Compare the constant rate and constant pressure solutions for key equations
The transition from conventional to unconventional
- Describe a horizontal well with multiple fractures
- Define Stimulated Reservoir Volume (SRV) and cross-sectional area to flow (Ac)
- List the expected flow regimes for a horizontal multifrac well
Data diagnostic workflow
- Navigate the Diagnostics tab
- Use a typecurve to evaluate data validity
- Filter data using automatic and manual methods
- Identify expected flow regimes using typecurves
- Determine contacted area from the flowing material balance
- Identify first linear flow with the specialized plot
- Estimate formation conductivity (Ac√k) and the time to end of linear flow (telf)
- Evaluate SRV parameters, including permeability and fracture half-length
- History match data to confirm interpretation
- Forecast future production and compare with decline forecasts
- Evaluate uncertainty with Monte-Carlo probabilistic methods
Advanced tools and methods
- Recognize pressure dependent permeability and apply geo-mechanical methods
- Apply adsorption to shale reservoirs
- Interpret gas-condensate or volatile-oil reservoirs with modified black-oil analyses
- Evaluate wells as re-fracturing candidates, or history match wells that have already been re-fractured
