Natural Gas Engineering

Course Description
At the end of this course, the students should be able to:
1. differentiate between different types of natural gas and calculate physical properties of
natural gas and associated gas;
2. differentiate between all types of gas reservoirs and identify the characteristics and
conditions for each type as well as calculate gas reserve in each type;
3. design gas well testing and analyse recorded data of pressure-flow rate for interpreting
initial reservoir pressure and expected skin factor as well as reservoir permeability;
4. analyse different types of gas reservoir deliverability tests and predict current and future
reservoir performance;
5. analyse decline rate data for predicting future gas reservoir deliverability using different
techniques of decline rate analysis (DCA);
6. identify different types of gas flow meters and apply mathematical models to calculate
gas flow rates;
7. design pipeline networks and gathering stations and apply mathematical models for the
optimum operating conditions at surface facilities;
8. handle the sour gas problem by suggesting various gas treating methods; and
9. describe the design of gas storage facility.
