..., and reservoir pore configurations. These factors contribute to the phase behavior of a particular CO 2 flood. Mixing as a result of diffusion improves microscopic displacement efficiency as compared to mixing by dispersion, which decreases microscopic displacement efficiency. Phase behavior governs...

Conventionally, pressure fall-off test data is analyzed using semilog plot of bottomhole pressure...

... Abstract The Minagish Oolite is a thick undersaturated carbonate oil reservoir in the Minagish field in West Kuwait ( Fig. 1 ) containing several billion STB. It is a mature but relatively undeveloped reservoir. Since discovery in 1959, it has produced 10% of its OOIP under a combination...

... will then be rich in both light and middle intermediate hydrocarbons, significantly richer than the gas at the flood front and almost completely miscible with the reservoir oil. CO₂Recovery Mechanisms. The means by which CO 2 increases oil recovery includes oil swelling, the reduction of oil...

... Abstract The cessation of CO 2 injection may be the result of poor reservoir response, low oil prices, or near the end of a CO 2 project. The focus of this paper is to describe the effect of CO 2 injection curtailment on oil recovery and production in a technically successful CO 2 flood...

... The San Andres is a shallow-shelf carbonate composed primarily of cyclical evaporates and carbonates. The gross reservoir thickness ranges from 300’ to 550’ and is composed of the Grayburg, upper San Andres and lower San Andres formations. The Lovington Sand often separates the upper and lower...

... Abstract Rienecke field is one of a series of fields in the Horseshoe Atoll of the Midland Basin. This carbonate reservoir has fairly good lateral and vertical continuity and is confined in a dome-like structure. A gravity-stable crestal carbon-dioxide flood was begun in 1997 by injection...
