Book excerpt: A study of the influence of viscosity ratio on recovery efficiency was carried out on an eight feet long unconsolidated sand model employing fluids native to an actual reservoir in the Lloydminster "heavy oil" area. The average properties of the two packs used were porosity 35«5 #j permeability 3*72 darcies. Thirteen tests were run at water saturations varying between 13.0# and 15*4#. The packs were preferentially water wet. Recovery efficiencies at breakthrough and WOR of 5:1 were obtained at viscosity ratios of 292, 646 and 1430. Viscosity ratio was controlled by temperature variation under a back pressure. Rate studies were carried out at viscosity ratios of 292 and 646 which revealed a lowering of displacement efficiency at higher rates. This loss in recovery was attributed to viscous fingering. Breakthrough recoveries at low rates were found to be 29.8# and 24.6# of initial oil in place at viscosity ratios of 292 and 646 respectively. A theoretical recovery versus viscosity ratio was established using Buckley-Leverett theory and experimentally determined relative permeabilities. Actual recoveries were higher than those predicted by theory. Pressure profiles were used to observe the progress of the front. There was some evidence that higher breakthrough recoveries would be possible with a longer model.

Book excerpt: The effect of aging and displacement temperatures, and brine and oil composition on wettability and the recovery of crude oil by spontaneous imbibition and waterflooding has been investigated. This study is based on displacement tests in Berea Sandstone using three distinctly different crude oils and three reservoir brines. Brine concentration was varied by changing the concentration of total dissolved solids of the synthetic brine in proportion to give brine of twice, one tenth, and one hundredth of the reservoir brine concentration. Aging and displacement temperatures were varied independently. For all crude oils, water-wetness and oil recovery increased with increase in displacement temperature. Tests on the effect of brine concentration showed that salinity of the connate and invading brines can have a major influence on wettability and oil recovery at reservoir temperature. Oil recovery increased over that for the reservoir brine with dilution of both the initial (connate) and invading brine or dilution of either. Removal of light components from the crude oil resulted in increased water-wetness. Addition of alkanes to the crude oil reduced the water-wetness, and increased oil recovery. Relationships between waterflood recovery and wettability are summarized.

This book was released on 2009 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: Waterflooding is by far the most commonly applied method of increasing oil recovery over that given by primary production. Reservoir wettability has been shown to be a key factor in determining the microscopic displacement efficiency in the swept regions of a waterflood. Reservoir wettability depends on complex crude oil/brine/rock (COBR) interactions. Numerous laboratory investigations and a growing number of pilot field studies show that oil recovery can be improved by injection of low salinity brine. This thesis includes study of the effect of low salinity flooding on oil recovery for selected reservoirs. Observations on the reproducibility of oil recovery behavior led to development of a new approach to improved oil recovery based on repeated waterflooding without change in brine composition. Laboratory studies indicated that the presence of the crude/oil interface was essential to oil recovery by sequential waterflooding. Crude properties have been measured for 27 crude oils. The oils were characterized according to density, viscosity, refractive index, surface tension, acid and base numbers, composition and vapor pressure. The effects of pH and salinity on interfacial tension were determined for a wide range of crude oils derived from both sandstone and carbonate reservoirs. A large majority of the oils exhibited low interfacial tensions at both low and high pH. For the selected COBR reservoir combinations, increase in oil recovery by low salinity waterflooding was often, but not always observed. The cost of recovering cores from a reservoir is very high. Furthermore, reservoir heterogeneity often limits the number of core samples that can be used in duplicate experiments. After testing, reservoir cores were therefore cleaned and reused. For a core that showed large response to reduction in injection brine salinity, it was found that the initial recovery, first measured for seawater, could not be reproduced, with recovery still being close to that given by the brine of lowest salinity. As a test of reproducibility, cores that had been waterflooded with high salinity brine were taken back to initial water saturation by oil flooding and re-flooded without change in the injection brine composition. For 15 out of 18 tests that included both sandstone and limestone, residual oil saturation decreased from one flood to the next. Reductions in residual oil saturation were not observed for recovery of refined oil. Material balances for sequential flooding were checked against Dean-Stark extraction and by tracer tests. The overall trend of reduction in residual oil saturation was confirmed by MRI imaging of changes in saturation distribution during sequential floods. Further investigation of this new approach to tertiary recovery is proposed through relatively low-cost single-well field tests.
