This research investigates the combined effect of grain size and water salinity on oil recovery. Water flooding experiment was carried out using unconsolidated formation from Niger Delta. Five groups consisting of five samples, were tested for the effective interaction of two factors (grain size and salin- ity) and how they affect oil recovery. Each group was as- signed a particular grain size while the prepared brine con- centration was varied within a specified range. The selected grain sizes were obtained from laboratory sieve analyses. For each sand sample, the same concentration of brine used in saturating it was poured into the accumulator and con- nected to the flooding tube to displace a column of crude oil. The control valve was opened to cause oil displacement. The amount of brine used to displace the crude oil was ten times the pore volume and all the oil in each sample was recovered by the saturated brine solution. Laboratory investi- gations show that oil recovery was highest for brine concen- tration of 15,0 0 0 ppm; this was also the case in relation to oil recovery and sand grain sizes.
