Geothermal Reservoir Engineering

---

Disciplines: Reservoir

Course Description

This Geothermal Reservoir Engineering 2-day course is designed by Dr. Roland N. Horne to teach participants how to:

• Apply knowledge of mathematics, science, and engineering to applications of geothermal energy.
• Formulate and solve engineering problems related to applications of geothermal energy.
• Use the techniques, skills, and modern engineering computational tools necessary for engineering practice.

The course will cover the following areas:

Simple Reservoir Modeling

• Diagram conduction and convection; explain which applies to a geothermal reservoir.
• Sketch a Boiling Point for Depth (BPD) curve for a fluid-dominated system and a vapor-dominated system and explain why they are different.
• Explain how and why the amount of energy in place in steam vs. water differs depending on whether it is measured by mass, energy, or volume.
• Explain the relative amounts of heat energy stored in water, steam, and rock. (Note the implications for geothermal resource exploration and energy generation.)
• Calculate the amount of wastewater produced vs. useful energy output for the given conditions.

Analysis of Measurements in Wells

• Calculate heat loss to surroundings by conduction.
• Estimate flow rates based on temperature and pressure logs.
• Interpret temperature and pressure logs to determine feed zone depths.
• Interpret temperature and pressure logs to determine reservoir pressure and temperature.
• Estimate the energy loss during single-phase and multiphase flows in wells.

Reservoir Simulation

• Use p/z models to estimate steam reservoir size and ultimate recovery.
• Use decline curves to estimate recoverable reserves.
• Construct a reservoir simulation model of a reservoir.
• Perform natural state modeling and history matching.
• Perform forecasts of future reservoir performance.

Reinjection Design

• Understand the pressure, thermal and chemical changes that take place in the reservoir during reinjection.
• Design tracer tests for the analysis of reinjection.
• Interpret tracer tests using porous medium and fractured medium models.
• Optimize the reinjection strategy.
• Understand the range of experience in reinjection at geothermal fields worldwide.
