..., surfactant polymer (SP) and alkaline surfactant polymer (ASP) have all been employed in the quest for better efficiency. However, grain size effect on the recovery system during these tertiary recovery techniques has received less attention over the years. This paper presents evaluation of the effects...

... Abstract It generally has been recognized by previous investigators that grain size is a fundamental independent variable controlling permeability in unconsolidated sediments. Several models that have been developed for estimating permeability based on grain size. However, these equations...

... and moderately sorted sands obtained from three different locations in the Niger Delta were determined. The results showed that porosity increases with decreasing grain size. It was generally observed that porosity increased from about 26% to 42% as the sand grain sizes decreased from 1000microns to 45microns...

... of surfactants and alkaline. In this work, the effect of viscosity of ASP on oil recovery was investigated on sand with varying hetrogenuity in terms of grain sizes. Background Abstract New development in technology and the rise in world oil prices give promises that substantial portion of otherwise...

... and permeability in deepwater reservoirs are available. We report on the main controls on porosity and permeability of deepwater reservoirs using core plug samples from several wells in Shell's deepwater portfolio. Results show that grain size control on permeability and sorting control on porosity...

... Abstract Recent advances in grain size distribution modelling have tended to de-emphasize the conventional method of carrying out grain size distribution analysis. This is a direct result of the difficulties surrounding core acquisition, preparation and analysis. Huge rig time spent acquiring...
