Alkaline flooding is an enhanced oil recovery technique that involves injecting an alkaline solution into an oil reservoir to reduce oil viscosity and improve oil displacement efficiency. This method is particularly effective in reservoirs with high acid number crude oils, as the alkaline solution reacts with acidic components to form soaps that aid in mobilizing trapped oil.

Alkaline solution

An oil reservoir is a subsurface pool of hydrocarbons contained in porous or fractured rock formations, which can be extracted and refined into usable products. These reservoirs are formed over millions of years through geological processes and are crucial for the global energy supply.

Reduce oil viscosity

Oil displacement efficiency refers to the effectiveness with which injected fluids, such as water or gas, can displace oil from a reservoir during enhanced oil recovery processes. It is crucial for maximizing oil extraction and is influenced by factors such as reservoir properties, fluid characteristics, and injection strategies.
