The results of the laboratory coreflooding experiments, which are performed on different core plugs taken from Indiana limestone (carbonate) reservoir, are presented in this study. To determine...

... on unpreserved shale core plugs using CO2, N2 and C1 as solvents, however, none have shown recovery results using ethane or higher molecular weight gases for cyclic gas injection. This paper presents improved oil recovery results from cyclic gas injection experiments using C2 and n-C5 in comparison to N2...

...Methodology Rock Properties and preparation The core plugs and chips used in this study are from the same batch of Eagle Ford outcrops. The plug samples are 2 inches in lengths and 1.5 inches in diameters. 12 core plugs in total contributed to the final results of this work. Rock properties...

... In this section, we present four recent imbibition experiments. These experiments guided our thinking regarding the impact of capillary osmosis on flow and oil recovery potential in petroleum reservoirs. Kurtoglu (2013 ) conducted an imbibition experiment in a Middle-Bakken core plug using two different...

... enables accurate determination of the original-oil-in-place for each of the core plugs prepared for the further experiment. The inability of continuous injection through the core sample is avoided by treating the process as a huff-n-puff. Experimental set-up of CO 2 EOR in this scheme is achieved...

... pressure, regardless of the MMP. We also postulated a kinetically slow peripheral vaporizing gas drive as the main recovery mechanism underlying the rationale for such operational philosophy. We based all of our findings in a collection of 21 experiments performed using crude oil and core plugs from...

... determined directly through core analyses at ambient and/or reservoir conditions. 20 core plugs were studied at both fully and partially saturated states. Results indicate that temperature is a major factor affecting the dielectric, NMR, and resistivity signals whereas pressure has less impact. Although...

Sample Preparation Core plugs were removed from the molds as soon as they were strong enough to support...

... Abstract Accurate determination of organic-rich shale permeability is still a major challenge. Various methods have been proposed to measure the permeability on core plugs or crushed samples under various stress conditions using different fluids. Permeability obtained from core plugs...
