Methods for Detecting Biofilm In-Situ from Seismic Data

BACKGROUND

Formation of biofilms is a predominant way of life for most microorganisms in the environment. Biofilms comprise extracellular polysaccharides (EPS), which is a gel type material playing a vital role in attachment of microbial cells to growth surfaces. Biofilms are quintessential byproducts of hydrocarbon degradation. Thus, their detection could be critical in assessing environmental remediation, carbon sequestration, and enhanced oil recovery. However, in-situ detection of biofilms in field conditions has remained an unresolved problem.

SUMMARY OF TECHNOLOGY

OSU researchers have developed a method for detecting biofilm in-situ in field conditions from seismic data. The invention is based on inventors' research on biofilms and seismic technology and has been proven through a combination of modeling, field experiments and laboratory tests. The developed method is also the first research that can detect in-situ biofilms growth in field conditions and will benefit many communities such as those perusing remediation, microbial enhanced oil recovery or CO2 sequestration.
