Core Principles of Enhanced Oil Recovery by Larry W. Lake
Larry W. Lake approaches enhanced oil recovery through a lens that combines reservoir
physics, fluid dynamics, and chemical interactions. His methodologies emphasize
understanding the reservoir’s geology, fluid characteristics, and operational constraints to
design tailored EOR solutions.
Types of Enhanced Oil Recovery Techniques
In his work, Lake categorizes EOR methods into three main types:
Thermal Recovery: Methods like steam flooding and in-situ combustion that
1.
reduce oil viscosity by increasing temperature.
Gas Injection: Using gases such as carbon dioxide (CO2), nitrogen, or natural gas
2.
to drive oil towards production wells or to swell the oil and reduce its viscosity.
Chemical Injection: Introducing polymers, surfactants, or alkaline agents to
3.
improve sweep efficiency and reduce interfacial tension between oil and water.

reservoir rocks and fluids, and the economic considerations of using them at scale. His
insights help operators design surfactant formulations that balance effectiveness with
cost, a crucial factor when deploying chemical EOR in mature fields.
