| Summary: | (isolated and multiple) rock samples. Rock properties such an alternative oil recovery method. This research was and images were recorded to visualize and quantify changes in as porosity, permeability, and initial oil saturation of the carbonated water imbibition in homogeneous and fractured carbonated water imbibition significantly reduced the conducted to evaluate oil recovery using unadulterated or Conventional waterflooding methods of oil recovery are difficult to apply when reservoirs show evidence of natural dramatic changes in oil saturation took place close to the exponential relationship between time and recovery, until fluid saturation inside the rock samples during the fractured systems. fractures, because injected water advances through paths of hand, carbonated water imbibition is more efficient in macro- high permeability, and oil trapped in the rock matrix system imbibition cumulative oil recovery curves exhibited an imbibition displacement tests. NMR oil saturation profiles imbibition faces. Unadulterated and carbonated water insensitive. Carbonated water imbibition increased oil is more effective than carbonated water imbibition to enhance is not displaced. Oil existing in these reservoirs could be Limestone rock samples. Homogeneous rock samples had a maximum oil production was reached and oil recovery became oil recovery from micro-fractured systems. On the other oil recovery from the matrix-fracture system is directly or two additional longitudinal symmetrical induced fractures out in homogeneous and longitudinal fractured, Indiana percent of oil by unadulterated water imbibition. Ultimate proportional to the area available for water imbibition. recovered by the imbibition displacement technique which is recovered from the rock matrix system was not always uniform recovery especially at earlier times. Additionally, recovery time when compared with the time to recover the same Resonance (NNM) sets of longitudinal and transverse profiles rock samples were measured. Experimental work was carried show that the percent of original oil in place (OOIP) simulated transverse fracture (macro-fracture) in front of the imbibition face, while the fractured rock samples had one the oil production potential. Unadulterated water imbibition Therefore, the presence of macro-and microfractures increases throughout the rock samples. As would be expected, the to simulate a n-iicro-fracture system.
