..., but an optimal value for a specific field depends on the anticipated oil saturation and the transportation length between injection/production well pairs. A compound's octanol/water partitioning coefficient (K OW ), provides a good indication for the candidate compound selection, but should be carefully...

... results in an oil recovery factor typically less than 50%. Waterflooding is by far the most widely used method to increase oil recovery. The oil that remains in the porous media after waterflooding is called remaining oil saturation (ROS) which is larger than the relative permeability residual oil...

... and high hydrocarbon saturation. Seminole exhibits highest hydrocarbon saturation and lowest value of standard deviation of porosity. Thus from this analysis it can be concluded that there exists a relation between porosity and saturation. High porosity values indicate low oil saturation ( Figure 3...

...) in a heel-to-toe configuration. The pilot test evolved into an oil rim recovery project with pressure support coming from a vertical injection well, due to reservoir heterogeneities and lower-than-expected oil saturations. Key technical aspects are discussed, including reservoir screening and the selection...

... produces only oil until the capillary pressure reduces to zero. Water is then produced in greater and greater quantities as the water saturation moves from the point of zero capillary pressure toward a residual oil saturation by imbibition. When imbibition ceases the imbibition capillary pressure curve...

Such discussion may be presented at the above meeting and, with the paper, may be considered for publication in one of the two SPE magazines. Abstract Gas and oil saturation are among the key values sought from a logging suite. The recent...
