Enhanced Oil Recovery by Gas Injection

Enhanced Oil Recovery (EOR) techniques have revolutionized the oil and gas industry, enabling the extraction of a greater percentage of hydrocarbons from reservoirs beyond what conventional methods can achieve. Among the most effective EOR methods is gas injection, where gases, such as carbon dioxide (CO2) or natural gas, are injected into reservoirs to enhance oil recovery rates. Gas injection EOR has proven to be a versatile and environmentally sound approach to optimize hydrocarbon production.

The Role of Gas Injection in EOR

Gas injection in EOR is employed to overcome the limitations of primary and secondary recovery methods, which often leave significant volumes of oil trapped in reservoirs. This method addresses several key challenges:

• Gas Drive: The injected gas acts as a drive mechanism, pushing oil towards production wells and displacing it from the reservoir.

• Enhanced Sweep Efficiency: Gas injection improves the sweep efficiency of injected fluids, reducing bypassed oil and increasing overall recovery.

Types of Gas Injection EOR

There are two primary types of gas injection EOR:

• CO2 Injection: Carbon dioxide (CO2) is one of the most widely used gases for EOR. It dissolves in oil, reduces its viscosity, and causes oil to swell, enhancing its flow properties.

• Natural Gas Injection: Natural gas, primarily methane (CH4), is another gas used in EOR. It can improve oil recovery through pressure maintenance and vaporization of light hydrocarbons.

Environmental Benefits

Gas injection EOR offers environmental advantages, including:

• Carbon Capture and Storage (CCS): When CO2 is used for EOR, it can be captured from industrial emissions, contributing to carbon mitigation efforts by preventing CO2 release into the atmosphere.

• Environmental Remediation: Repurposing abandoned wells for geothermal energy can also address environmental concerns associated with well abandonment, such as potential methane emissions.

Geothermal Energy Extraction

The process of extracting geothermal energy from abandoned wells involves:

• Fluid Circulation: A heat transfer fluid, typically water, is circulated downhole through the wellbore, where it absorbs heat from the surrounding rocks.

• Surface Heat Exchangers: The heated fluid returns to the surface, where its heat is transferred to a working fluid in a surface heat exchanger.

• Power Generation: The working fluid is used to generate electricity through conventional power generation methods, such as steam turbines or organic Rankine cycles.

Advantages of Abandoned Well Geothermal

Harnessing geothermal energy from abandoned wells offers several significant advantages:

• Renewable and Sustainable: Geothermal energy is a clean and renewable resource, producing minimal greenhouse gas emissions and contributing to the reduction of carbon footprints.

• Resource Availability: Abandoned wells are widespread across oil and gas-producing regions, providing ample opportunities for geothermal development.
