Geothermal Reservoir and Hydraulics Design
This 1-day course is an introduction to analysis and design of the geothermal reservoir and wellbores. The following topics will be covered:
Analysis of Geothermal Reservoir:
- Introduction of geothermal reservoir
- Conduction and convection in the geothermal reservoir.
- Comparison of fluid-dominated and vapor-dominated systems
- p/z models to estimate steam producing geothermal reservoir size
- Empirical Decline-curves to estimate recoverable energy.
- Compressibility of two-phase water and steam system
- Capillary pressure model of two-phase water and steam system
- Construct a reservoir simulation model.
- Construct the Hydraulic-Fracture model with cohesive elements
Analysis of Geothermal Wells:
- Heat Loss in a wellbore
- Steam flashing in a vertical section
- Effect of impurity in steam flashing
- Flow Patterns in Steam/water flow in vertical section
- Geothermal power generation
- Countercurrent heat exchange in coaxial wells, and applications such as jet-pump
- Propagation of the hydraulic fracture in EGS applications
At the end of this course, participants will be able to:
- Become familiar with fundamentals of steam-water flow in vertical section.
- Carry out well-test methods on geothermal reservoir.
- Learn assumptions made in p/z model.
- Estimate the Geothermal power generation.
- Understand benefits and limitations of Geothermal operation.
- Understand the challenges in the modeling of the AGS and EGS
The temperature of the earth's inner core is about 6000°C, which is as hot as the surface of the sun. Temperatures in the mantle range from about 200°C at the upper boundary with the earth's crust to approximately 4000°C at the mantle-core boundary. Such high temperature creates a continuous source of energy for electrical energy. Geothermal energy is used in over 20 countries. This course presents the fundamentals of analysis and design of the geothermal projects.
Production engineers, reservoir simulation engineers need to move into geothermal operation. And new and experienced geothermal reservoir engineers. And technology development leaders that are involved in evaluation of geothermal operation.
- Students must bring their own laptops.
- Participants should have understanding on one-phase flow in the pipe such as its frictional pressure calculation.
- Participants should have basic knowledge of Microsoft Excel.
- Participants should have moderate experience or exposure to the topic.

Mazda Irani is acting as a CTO of Ashaw Energy. He is currently engaged in the designing and optimization of Steam Assisted Gravity Drainage (SAGD) and proper near wellbore modeling for the SAGD wells. One of his main tasks is to help and develop a software that can help operators run their SAGD wells at optimum subcool, manage the hot spots, and modify their FCD design in heterogeneous reservoirs. He published a trilogy paper named “On Subcool Control in Steam-Assisted-Gravity-Drainage Producers"
Dr. Irani was previously employed in technical and supervisory roles with Cenovus Energy, Suncor Energy, RPS Energy, and C-FER Technologies. He has published and presented more than 40 technical papers on different aspects of SAGD operation. Dr. Irani holds a PhD in petroleum engineering (U of C 2017) and geomechanics (U of A 2012) and three Masters degrees in petroleum engineering, geotechnical engineering, and structural engineering.
