An example is found in certain regions of the Gulf of Mexico, where high-pressure reservoirs allow for sustained natural flow. However, as reservoir pressure declines, artificial lift methods often become necessary.
-
Artificial Lift Extraction
Artificial lift methods are employed when the reservoir pressure is insufficient to maintain natural flow. Techniques include using pumps, such as sucker rod pumps, or injecting gas into the wellbore to lighten the fluid column, a process known as gas lift. Sucker rod pumps are often used in mature fields where the reservoir pressure has declined over time. Gas lift is commonly applied in offshore operations or in wells with high water production, increasing the buoyancy of the gas and facilitating its upward movement.
-
Enhanced Gas Recovery (EGR)
Enhanced Gas Recovery involves injecting fluids, such as carbon dioxide or nitrogen, into the reservoir to increase pressure and displace natural gas towards the wellbore. EGR techniques can extend the productive life of a natural gas field and increase overall recovery rates. This method is particularly useful in depleted reservoirs where primary and secondary recovery methods have been exhausted. Pilot projects have demonstrated the feasibility of EGR in various geological settings, often coupled with carbon sequestration efforts.
