PE3003 Enhanced Oil Recovery Technologies Syllabus:
PE3003 Enhanced Oil Recovery Technologies Syllabus – Anna University Regulation 2021
OBJECTIVE:
To impart knowledge on how residual oil is recovered and the problems associated with Enhanced Oil Recovery.
UNIT I FUNDAMENTALS OF ENHANCED OIL RECOVERY
Pore Geometry, Microscopic aspects of displacement. Residual oil magnitude and mobilization. Buoyancy forces and prevention of trapping, Wettability, Residual oil and Oil recovery. Macroscopic aspect of displacement.
UNIT II WATER FLOODING
Properties, sampling and analysis of oil field water; Injection waters; Water flooding – Sweep efficiency, Predictive techniques, Improved water flood processes, Performance of some important water floods.
UNIT III ENHANCED OIL RECOVERY OPERATIONS – 1
Flooding – miscible, CO2, polymer, alkaline, surfactants, steam
UNIT IV ENHANCED OIL RECOVERY OPERATIONS – 2
Gas injection, in-situ combustion technology, microbial method.
UNIT V PROBLEMS IN ENHANCED OIL RECOVERY
Precipitation and deposition of Asphaltenes and Paraffin’s, Scaling problems, Formation of damage due to migration of fines, Environmental factors.
TOTAL: 45 PERIODS
OUTCOME:
On completion of the course students are expected to
CO1: Understand the purpose of enhanced recovery process.
CO2: Understand the concept of capillary force, viscousforce and how it traps the oil.
CO3: Understand the sampling and analysis of reservoir fluid and to develop flooding fluid which is suitable for that particular field.
CO4:Understand the flooding mechanisms.
CO5: Understand how gas injection works to maintain the reservoir pressure and to understand the mechanism leading to positive skin.
