Proceedings Papers

Paper presented at the SPE Permian Basin Oil and Gas Recovery Conference, May 15–17, 2001
Paper Number: SPE-70035-MS
... similar information to that obtained from production tests concerning the well and the reservoir characteristics but also allows the mobility ratio between the injected and resident fluids to be determined. Conventionally, pressure fall-off test data is analyzed using semilog plot of bottomhole pressure...

Paper presented at the Permian Basin Oil and Gas Recovery Conference, March 27–29, 1996
Paper Number: SPE-35208-MS
...-horizontal permeability ratio, injection and production rates, and reservoir thickness have little effect on waterflood oil recovery for a particular water-oil mobility ratio. For both vertical and horizontal well systems, oil recovery decreases with increasing mobility ratio. It is concluded...

Paper Number: SPE-17289-MS
... the injection rate, vertical permeability variation, ordering of beds, mobility ratio and the ratio of vertical to horizontal permeabilities. A five beds, linear model was used under wide range of operating conditions. Based on the study, it was observed that the oil recovery and cross flow index were...

... the oil from the reservoir. However, miscible gases are generally lighter than in-situ oils and thereby tend to segregate to the top of the production interval. 1 Adverse mobility ratios and reservoir heterogeneity can aggravate the poor vertical sweep offi- ciency. 2 In order to alleviate the severity...

... controlled by the mobility ratio. Equations giving the pressure drop, time of breakthrough, water-front location, coverage, WOR and cumulative oil recovery in a layered-composite reservoir are presented. Application of these equations to the case of constant injection pressure, which was not treated...

Paper presented at the SPE Permian Basin Oil Recovery Conference, May 10–11, 1965
Paper Number: SPE-1144-MS
... On sand-packed areal models utilizing oil and water solutions with an oil-water viscosity ratio of approximately 1. A second series of tests was made on Hele-Shaw (fluid mapper) models utilizing glycerol solutions to represent both oil and water with mobility ratios of 1, 3.5 and 9.2. Based on the sand...
