JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Course Objectives

• To learn and be able to apply the basic quantitative tools of reservoir and production engineering techniques to analyze and/or predict the mechanics of natural gas flow through the reservoir–production-transportation system.
• To understand the importance of evaluating and managing the reservoir-production system of gas reservoirs.
• To familiarize with various principles/ involved in natural gas engineering.

Course Outcomes

The students would be able to

• Understand basic fluid phase behavior, and be able to determine the physical properties of natural gas.
• Able to use volumetric method, material balance equation and decline curves to perform reserves and performance prediction/enhancement of dry and wet gas reservoirs.
