Current methods of through-casing saturation determination using nuclear tools are limited because of their shallow...

... 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...

... 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...

..., technical, and economical limitations. This paper describes a new CO 2 injection method that combines all three of these methods but excludes water injection. Continuous CO 2 may be optimal in reservoirs that are not conducive to water injection and do not have CO 2 mobility control problems...

..., 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...

... Abstract A team was formed to solve field-wide conformance problems in a San Andres (dolomite) unit of the Slaughter Field, Hockley Co., Texas. The team's goal was to increase oil production and decrease production costs by understanding fluid movement through the reservoir. The team...

.... The production performance of this case is compared here with the 160-acre depletion case ( Figure 6 ). The oil recovery from the waterflood operation was computed to be more than double the primary recovery. Abstract Integrated geoscience and engineering software plays a key role in providing reservoir...

... Abstract Although fracturing is an established technology with a wide range of usage, certain reservoir scenarios that appear to be good candidates for its application do not benefit from its usage. Examples of these reservoirs include stratified wells in which some of the layers are water...

... The Spraberry Trend of West Texas is a naturally fractured reservoir (NFR). A map of the Spraberry area is shown in Figure 1 . This Permian age formation is divided into the Upper, Middle and Lower formations (see type log depicted in Figure 2 ). The Upper Spraberry, at a depth of approximately...
