Microbial flooding agent

Product Overview

Description

vvThe microbial formulation for enhancing oil recovery is composed of functional microbial flora, biosurfactants, biopolymers and corresponding nutrients.

Performance and Mechanisms

 

Microorganisms as well as their metabolites can enhance oil recovery with one or more abilities such as reducing oil-water interfacial tension, increasing reservoir pressure, reducing crude oil viscosity, improving the mobility ratio of oil and water, selectively plugging high permeability oil bearing layers. Strategies have been developed for promoting the effect of field applications including optimizing the composition of functional microbial flora according to their physiological properties and the specific conditions of target oil reservoir, real time analysis of microorganism activity and the production dynamics.

 

Advantages

Microbial enhancing water flooding technology has the advantages of simple implementation, no damage to oil layers, no impact on crude oil quality, no pollution, low investment, quick funds return, high profitability.
