JAWAHARLAL NEHRU TECHNOLOGICAL UNIVERSITY HYDERABAD

Prerequisites

Chemical Engineering Fluid Mechanics, Petroleum Reservoir Engineering

Course Objectives

The students are expected to get knowledge of

• Fundamental concepts in petroleum production engineering.
• Reservoir fluids, efficient flow to the surface without damaging the reservoir dynamics/drive mechanisms.
• Various surface equipment’s for process oil and gas after flow from wells.
• Sick well identification and remedial stimulation operations.
• Application of suitable artificial lifts on reservoir energy depletion.
• Crisis management.

Course Outcomes

After the course, the students will be able to:

• Determine the well head pressure, down hole pressure and operating oil/ gas flow rates of the reservoir.
• Identify formation damage and find remedial methods to bring the well back into production.
• Screen, design and operate artificial lifts on reservoir pressure depletions.
• Handle in case of any crisis at drilling/production installations.
• Process oil and gas before supply to refinery/consumers.
• Contribute to reservoir management as production engineers to prolong the reservoir life with optimum production.
