Implication

Experimental analysis reveals enhanced oil recovery through a gel-microbial system in heavy oil reservoirs, indicating improved displacement efficiency.

Key Points

A novel gel-microbial system significantly enhances oil recovery by integrating multiple mechanisms.
The study demonstrates a fourfold increase in displacement pressure through effective flow path blockage.
Bacillus licheniformis produces biosurfactants, reducing oil-water interfacial tension by 61.9% and viscosity by 65%.
Ultimate oil recovery achieved 15% and 20% in one-dimensional and two-dimensional models, highlighting its potential.
