Enhanced Oil And Gas Recovery

Enhanced Oil And Gas Recovery Is The Process Of Increasing Or Improving The Recovery Of Oil And Gas From A Reservoir. This Is Achieved Through The Use Of Enhanced Oil Recovery Techniques, Which Are Designed To Recover Additional Oil And Gas From A Reservoir That Has Already Been Tapped. Enhanced Oil And Gas Recovery Techniques Are Broadly Classified Into Three Categories, Which Are Primary, Secondary And Tertiary. Primary Recovery Is The Simplest Form Of Recovery And Utilises The Native Pressure Of The Reservoir To Bring Oil And Gas To The Surface. As The Reservoir Pressure Decreases, Secondary Recovery Techniques Become Necessary. These Techniques Involve The Injection Of Fluids Or Gas Into The Reservoir In Order To Push Additional Oil And Gas To The Surface. One Of The Most Common Techniques Is Water Flooding. This Is Where Water Is Injected Into The Reservoir To Displace Trapped Oil And Gas So It Can Be Recovered. The Third Category Of Enhanced Oil And Gas Recovery Is Known As Tertiary Recovery. This Is The Most Advanced Form Of Recovery And Involves The Injection Of Substances Such As Steam, Oil-Recovery Polymers, Or Carbon Dioxide Into The Reservoir. These Substances Increase The Viscosity Of The Oil So That It Displaces More Easily And Increases The Recovery Rate. Enhanced Oil And Gas Recovery Techniques Are Important For The Oil And Gas Industry As They Make It Possible To Recover More Oil And Gas From Existing Reservoirs. This Has The Benefit Of Enabling Oil And Gas Companies To Increase Their Profits, While Helping To Reduce The Global Demand For New Reserves Of Oil And Gas. Despite The Increased Complexity Of These Techniques, They Are Often Used In Combination With Other Technologies, Such As Horizontal Drilling, To Maximise The Recovery Rate.
