Title: Development of an Improved Waterflood Optimization Program in the Northeast Savonburg Waterflood
Abstract: Abstract The Savonburg Field, a shallow reservoir located in southeastern Kansas, has production problems which are common in fluvial dominated deltaic reservoirs and other areas of the country where stripper-well production is important. The problems relate to poor waterflood sweep and lack of an integrated reservoir management program. The poor water-flood sweep efficiency is due to (1) reservoir heterogeneity, (2) channeling of injected water through high permeability zones or fractures, and (3) clogging of water injection wells with solids as a result of poor water quality. Reservoir management suffers from the lack of (1) sufficient data collection and organization, (2) integrated analysis of existing data by geological and engineering personnel, and (3) identification of optimum recovery techniques. A project to increase oil recovery from the Savonburg Field is being conducted under the DOE Class 1 Program. The objective is to improve waterflooding through integrated reservoir management. To date, two technologies have demonstrated positive economics. An air flotation unit has demonstrated that the poor water quality can be improved economically with reduced costs compared to previous operations. Permeability modification treatments plugged channels and increased oil recovery. Earlier treatments yielded five barrels of incremental oil per pound of polymer injected and recent treatments have improved injection profiles. Reservoir characterization studies identified unswept oil in the lower B3 zone and as a result two waterflooding patterns were modified and a new injection well was drilled. Incremental oil is expected to result from this change.
