OIL RECOVERY ENCHANMENT TECHNIQUES

COURSE OBJECTIVE:

• Develop recovery expectations from reservoirs under primary depletion or pressure maintenance utilizing water or immiscible gas injection
• Determine reasons and causes for less than theoretically possible recovery 
• Choose appropriate methods (with their target applications, benefits, and limitations) for improving oil recovery from reservoirs under primary depletion or pressure maintenance utilizing water or immiscible gas injection 
• Enhance oil recovery beyond waterflooding or immiscible gas injection project 
• Understand mechanisms responsible for recovery improvement in various EOR methods 
• Use miscible methods: Injection of solvents (LPG/NGL injection, gases such as natural gas, carbon dioxide, nitrogen, flue, etc.) in the reservoir
• Use chemical methods: Injection of chemicals (polymers, surfactants, caustic soda, etc.) in the reservoir 
• Use thermal methods: Introduction to heat (hot water, steam, combustion; inter-well and huff-&-puff) in the reservoir Important variables that control recovery  improvement in various EOR methods 
• Select EOR methods using screening criteria
• Use designing procedures – theoretical, laboratory tests, and field pilots 
• Plan and impliment EOR processes employing the proper empirical, analytical, and simulation tools
• Forecast rate-time and recovery-time behavior under various EOR methods and analyze reservoir performance 
• Assess risks and ways to minimize their impact on project economics 
• Monitor reservoir/well behavior.

WHO SHOULD ATTEND:

     Engineers responsible for sustaining or increasing oil and gas production and enhancing oil recovery from reservoirs under primary depletion, pressure maintenance by water or gas injection, and enhanced oil recovery schemes.
