Secondary and Tertiary Methods When reservoir pressure declines, secondary recovery introduces external fluids like water or gas to maintain pressure and push oil toward the well. Economic viability remains a constant concern, as fluctuations in global market prices can render high-cost projects unfeasible.

This initial phase is often the least expensive but yields only a fraction of the total resource. Conversely, low prices can force operators to defer capital expenditures, leading to supply shortages down the line.
Operational Challenges and Considerations Executing a successful extraction project involves navigating complex geological variability and surface constraints. High-pressure fluid is then injected into the well to fracture the rock or displace the viscous hydrocarbons, forcing them to flow up the borehole to the surface.

Primary recovery utilizes the natural pressure of the reservoir, similar to squeezing a sealed bottle of soda. Engineers drill a wellbore to reach the target formation, inserting steel casing and cement to ensure structural integrity.
