Course content

The course will cover the following topics:

  1. Well deliverability using back-pressure analysis including pressure losses in the reservoir, tubing, and distribution pipelines.
  2. Gas material balance including water influx.
  3. Rate decline analysis.
  4. Gas well testing.
  5. Field production performance and forecasting.
  6. Engineering issues in developing a gas field.
  7. Gas condensate reservoirs.
  8. High-pressure reservoirs.
  9. Layered (no-crossflow) performance characteristics.

Learning outcome

Ingress: The students should know fundamental flow in porous media and pipe, and general reservoir recovery processes, including advanced phase behavior.

Knowledge: The student should understand flow in porous media, flow in pipe, gas material balance, and extensive use of oil and gas PVT calculation methods.

Skills: The students should understand the application of equations of state, black-oil PVT and use of Excel and SENSOR reservoir simulator to describe flow and material balance equations for gas and gas condensate reservoirs.

General competence: The student should learn to solve problems without solutions being handed out (only provided through in-class partial solutions by the teacher) - i.e. relying on their own ability to check and cross-check their work with others, in addition to using the lectures to ask questions about their solutions to problems. Critical self-learning is emphasized. Self-study is also required to decide what supportive reading is needed to understand (1) lectured material and (2) class problems - these two defining the course curriculum.

Learning methods and activities

The course will be given as a seminar with self-study curriculum when fewer than 5 students apply to take the course. Students planning to take the course must give a written request to the teacher for taking the course prior to the semester start. A class project will involve the building a geologic and numerical model to describe a gas field. Simulations of different depletion strategies will be made. Optimization of well and field performance will be made, including design for the number of required wells, tubing size, pipeline size, etc. The course will be held in English.

Compulsory assignments

  • Exercises

Further on evaluation

In order to pass the course, the student has to pass both the compulsory exercises / project (50%) and the final oral exam (50%). To pass a score of at least 70 percent is required. For a re-take of an examination, all assessments during the course must be re-taken.
