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

The course should teach how to evaluate gas well and field performance.

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.
