Biologically controlled water diversion demonstrated by new visual experimental technique
A microbial enhanced oil recovery (MEOR) technology for optimization of waterflood sweep efficiency was studied using a transparent pore micro model and a recently developed cybernetic image processing method (Automated Microscope Observation Reaction System = AMORS). Indigenous seawater microbes were stimulated with a nutrient package and allowed to develop inside the once through flow cell; a replica of the pore structure of a North Sea sandstone reservoir. The use of micro models fitted with the AMORS package is an important step in revealing the nature of microbial blocking phenomena in porous matrices. Reservoir potential evaluation and consideration of MEOR process logistics, as compared to alternative treatment methods indicates that selective biological diversion may be a highly cost-effective and controllable way of optimizing waterflood sweep efficiency in many North Sea reservoirs. AMORS is a flexible tool recommended for investigating processes that take place on a micro/macro scale.
