Potential of Enzyme treatment for the Enhanced Recovery of Crude Oil: 2021-2022

Enzyme well injection treatment is an emerging enhanced oil recovery (EOR) method. Several studies have been conducted on enzyme enhanced oil recovery (EEOR) at the academic, laboratory and field-scale.

These studies have demonstrated the positive effect of enzyme application with additional oil production being observed in initial but restricted production, as well as both secondary and tertiary injection phases. Enzymes are eco-friendly and they have the additional advantage of their catalytic nature. Enzyme production for EEOR implementation has evolved over the years with different types of commercial products tested and now available.

Enzymes are biological catalysts that expedite reactions that will otherwise proceed slowly without them. Naturally, all proteins have surface activity potential due to the presence of both hydrophilic and lipophilic groups within their molecules. Although, natural proteins are slow and inefficient as surface active agents, they can be modified into enzymes with more suitable amphiphilic compounds and augmented surface activity.

Enzyme activity can be affected by diverse variables such system temperature, chemical composition of the environment such as pH, presence of other electrolytes as well as composition of the substrate. Enzymes, as globular protein, respond to change in their environment and they exhibit thermodynamically stability in aqueous medium due to their high hydrophilic nature.
