Experimental Design for Evaluation of Formation Damage by Microbial Contamination in Water Flooding Processes. A Colombian Study Case.
Microbial contamination is well known in the oil and gas industry and it occurs in most processes where water processing systems are involved. Microorganisms are spread everywhere, even in the subsurface, where operations of oil exploration and production are developed. For this reason different gen...

Microbial contamination is well known in the oil and gas industry and it occurs in most processes where water processing systems are involved. Microorganisms are spread everywhere, even in the subsurface, where operations of oil exploration and production are developed. For this reason different genera of microorganisms can affcet the Oil & Gas Industry. One of the major problems in oil mature fields undergoing secondary recovery is the contamination with sulfate reducing bacteria (SRB), caused generally by the injection water system (fresh and/or production) and/or of the reservoir (natural or by drilling fluids, completion, simulation, etc). This problem causes formation damage and microbiological induced corrosion (MIC) in the injection-production system. In many producing wells, formation damage by microbiological contamination is initially masked by a decline in reservoire pressute; however, initial production of H2S does provide a possible microbial contamination of water production, water injection, and eventually, petroleum reservoir. In some production wells, H2S concentrations have exceeded the lethal limits of 250 ppm and there are cases of producing wells with levels above 1000 ppm. In this work, both a conceptual study and an experimental protocol were developed for the evaluation of formation damage by microbial contamination in water flooding processes, focused on finding the best stimulation treatment with biocides to H2S and corrosion control in producer wells of Oil Fields Undergoing Secondary Recovery as part of the comprehensive strategy to implement in the injection-reeservoir- production system of the Chichimene field in Colombia. This stduy included the following stages:

3. Experimental protocol to evaluation of formation damage by microbial contamination in water flooding processes.
4. Experimental evaluation of formation damage by microbial contamiantion in cores of the Chichimene field in Colombia.
Finally, the main findings, conclusions and recommendations obtained in this study are shown. |
