... nearly neutral-wet to strongly-water-wet conditions. In fractured chalk reservoirs waterflood residual oil saturation is strongly dependent on the wettability. The current results provide assistance in determining the potential target for tertiary oil recovery by measuring the amount of mobile oil...

... Abstract Reservoir performance during waterflooding is important to reservoir engineers. Analytical and semi-analytical flow models with different assumptions have been presented and used widely to describe the flow dynamics of such a process. Most assume that one of the terms, typically...

... Abstract Waterflood management for naturally fractured reservoirs is a difficult task due to complex fluid behaviors between fracture and matrix. The streamline model is particularly useful for assessing the individual contribution of injectors to each producer accounting for inter-porosity...

... Abstract The removal of sulfate from injected seawater for waterflood and pressure maintenance operations has become widely accepted for reservoirs with sulfate scaling potential. The technology has been found to be exceptionally useful in deep water and subsea operations where scale controls...

... is so far not possible. In this study, a critical review of literature on the field and laboratory results and theoretical modeling work is first made. Employing a simple pore-level model and the well-established capillary number correlation, mobilization of waterflood residual oil by seismic vibration...

... productivity wells, as well as waterflooding as part of an enhanced oil recovery program. During a preliminary waterflooding pilot project in 1999, a maximum injection rate of 4,000 BPD was applied to well AF-847. After 167 days of injection, the well capacity decreased to 1,920 BPD. Acidizing with 15% HCl...

... A thorough analysis of the facilities required for the massive waterflooding and for the gas injection initiatives was completed. It started with the injectivity analyses at the well and formation levels to asses pressure drops from the well up, in order to build a pressure model...

... exists in four horizons. The field is mature with over 10 years of historical production data from waterflood operations. The paper discusses issues relating to identification of the best application of IWT in the field and quantification of the potential gains from such application when compared...

... Abstract During the last 15 years, polymer gels have become an accepted technology for improving volumetric sweep efficiency in heterogeneous waterfloods. Water injected subsequent to the gel treatment ideally enters previously unswept zones with significant mobile oil saturation. Results from...
