GEOTHERM 602 : Geothermal Energy Technology

Engineering

2024 Semester Two (1245) (15 POINTS)

Course Prescription

Worldwide geothermal development, types of geothermal systems, thermodynamics, properties of water and steam tables, heat transfer, fluid mechanics, steam-field equipment, geothermal power stations, geothermal drilling, wellbore processes, completion tests, downhole measurements, reinjection, corrosion, stored heat, Darcy's law, cold groundwater, geothermal reservoirs, direct use, reservoir modelling, reservoir monitoring and steam-field management.

Course Overview

The course provides an introduction to Geothermal Engineering, it is designed to give an overview of the use of fundamentals (Thermodynamics, Fluid mechanics, and Heat transfer) in geothermal engineering. This is to ensure that all students learn a basic level of understanding of geothermal and reservoir engineering starting from; geothermal drilling, well testing, steam field equipment, power plants, and direct-use applications of geothermal energy. This is with a focus on hands-on field activity to give the students a feel for the different designs of geothermal utilization facilities and the ability to compare and contrast different plant components. Also an appreciation of geothermal drilling and well testing equipment.

It also provides non-engineering students with an appreciation and understanding of geothermal engineering and develops a multi-disciplinary approach to geothermal energy exploration and development.  
  
GEOTHERM 602 is a block-structured course that combines class and field-based education. It runs over the first six weeks of Semester two and along with course GEOTHERM 601.

Learning Outcomes

By the end of this course, students will be able to:
  1. Demonstrate an understanding of the laws of thermodynamics and their applications in geothermal energy applications and solve practical problems (Capability 3.1, 3.2, 4.1, 4.2, 5.1 and 6.1)
  2. Demonstrate an understanding of the fundamentals heat transfer: Fourier law of thermal conduction, Newton’s law of cooling, the Stefan Boltzmann law on thermal radiation and their applications in the geothermal energy. Solve practical problems in geothermal heat transfer. (Capability 3.1, 3.2, 4.1, 4.2, 5.1 and 8.1)
  3. Demonstrate an understanding of the fundamentals laws of fluid mechanics and their applications in the geothermal engineering. Solve practical problems of geothermal steam and liquid flow in geothermal pipelines. (Capability 3.1, 4.1, 4.2, 6.1 and 7.1)
  4. Demonstrate an understanding of the engineering classifications of the different types of geothermal systems and the impact of this classification on the geothermal resource development and management. The geothermal resources have an important cultural and economic value to both the public specially to local Iwi. understanding the impact and development risks is also key to ensure the safe and sustainable use of these resources. (Capability 1.1, 2.1, 3.1, 3.2, 4.1, 4.2, 5.1 and 6.1)
  5. Develop and demonstrate an understanding to the principles of geothermal drilling, coring, site preparations and drilling equipment. If not managed correctly, geothermal well drilling can result in hydrothermal below outs, which can put people health at safety at risk and directly impact the sustainability of the geothermal resource. (Capability 1.1, 2.1, 3.2, 4.2, 5.1, 6.1 and 7.1)
  6. Analyse and evaluate down-hole measurement methods and the tools and techniques to assess geothermal well performance. Health and safety are a major consideration when operating geothermal wells. This is to ensure a long term and sustainable application while adhering to the RMA and maintaining the resource for future generations. (Capability 1.1, 2.1, 3.2, 4.1, 4.2, 5.1, 7.1 and 8.2)
  7. Demonstrate an understanding of the advantages and disadvantages of geothermal fluid reinjection and the environmental impact. Reinjection of both geothermal water and gases is key for the long-term sustainability of the resource, it is also a legal requirement in New Zealand and many other countries around the world. If not managed correctly it can result in significant health and safety risks to the local communities. (Capability 1.1, 2.1, 5.1, 6.1, 7.1, 8.1 and 8.2)

Workload Expectations

This course is a block-structured 15 point course and students are expected to spend on average 16 hours per week for 6 weeks only.

For this course, you can expect 40 hours of lectures, 30 hours of tutorial (including the field trip), 40 hours of reading and thinking about the content, and 40 hours of work on assignments and/or test preparation.

Delivery Mode

Campus Experience

Attendance is required at scheduled activities including lecture, tutorials and field trips to complete components of the course.  

Lectures and tutorials will be available as recordings.  However, the field activities will not be recorded. 

The course will not include live online events.   

Attendance on campus is required for the tests.   

The activities for the course are scheduled as a block delivery.   

Learning Resources

Course materials are made available in a learning and collaboration tool called Canvas which also includes reading lists and lecture recordings (where available).

Please remember that the recording of any class on a personal device requires the permission of the instructor.

All learning resources (lecture material) are provided to the students with additional reading material and data given on Canvas. 

Health & Safety

Students must ensure they are familiar with their Health and Safety responsibilities, as described in the university's Health and Safety policy.

There are three days of field activity, which requires extensive preparations and the development of a detailed Health and Safety management plan. PPE gear will be provided to the students. The students are also advised (before starting the course) to bring personal safety boots, and warm and wet weather gear.

In preparation for the field trip, Students should declare (in Confidence to the program director) any health issues.  

Student Feedback

At the end of every semester students will be invited to give feedback on the course and teaching through a tool called SET or Qualtrics. The lecturers and course co-ordinators will consider all feedback and respond with summaries and actions.

Your feedback helps teachers to improve the course and its delivery for future students.

Class Representatives in each class can take feedback to the department and faculty staff-student consultative committees.

The course was very well received by the students. The overall SET evaluation summary score for 2023 is: 4.94/5

Most positive feedback:
All the materials are very helpful as I learned a lot of new things that will be helpful for my career. The explanation is very clear so as a person with no engineering background, I can still understand it. The fieldtrip is also very great. In only two days, student already have learned a lot of things from several fields. The experience of visiting several power stations in TVZ was very valuable.

Most negative feedback:
The intensity of the courses, the way that everything (assignments, lectures) was arranged. But it was necessary since we only took 2 courses in the first half of the semester, and 1 in the second half, not including the research project. And maybe the mark for the field trip should be increased to 15 or 20 since the workload was significantly heavy. We worked on it for quite a few days compared to the other assignments.

We always strive to improve the course delivery and the student experience. The lecture material will be updated and the workload across the different assignment will be balanced. 

Other Information

Given the block-structured nature of the course (6 weeks) it may not be possible to do the course alongside other standard courses that run over the full semester.    
This course has to be taken along with GEOTHERM 601.  

Academic Integrity
