The primary objective of this project is to enhance domestic petroleum production by demonstration and technology transfer of an advanced oil recovery technology in the Paradox basin, southeastern Utah. If this project can demonstrate technical and economic feasibility, the technique can be applied to approximately 100 additional small fields in the Paradox basin alone, and result in increased recovery of 150 to 200 million barrels of oil. This project is designed to characterize five shallow-shelf carbonate reservoirs in the Pennsylvanian (Desmoinesian) Paradox Formation and choose the best candidate for a pilot demonstration project for either a waterflood or carbon dioxide-(CO{sub 2}) flood project. The field demonstration, monitoring of field performance, and associated validation activities will take place in the Paradox basin within the Navajo Nation. The results of this project will be transferred to industry and other researchers through a petroleum extension service, creation of digital databases for distribution, technical workshops and seminars, field trips, technical presentations at national and regional professional meeting, and publication in newsletters and various technical or trade journals. Five activities continued this quarter as part of the geological and reservoir characterization of carbonate mound buildups in the Paradox basin: (1) regional facies evaluation, (2) evaluation …

Experimentation was conducted to determine the nature of bubbling fluidized bed (BFB) pressure fluctuations. The goal of the experiments was to explain the physical phenomena that governs the structure of pressure fluctuations. A study of the effect of the differential pressure tap spacing was conducted. The results confirmed the hypothesis that spatial aliasing can significantly distort expected fluctuation structure. The behavior of bubbling bed fluctuations was compared to previously published theories that predicted the natural frequency of incipiently fluidized beds. A modified theory was derived for fluidized systems which better predicts the observed frequency in shallow fluidized beds. This theory not only predicts the natural frequency of bed oscillations, but also explains the second order system behavior observed in bubbling fluidized bed Bode plots. The effect of bubble coalescence in deep bed acts both to decrease the frequency of bed oscillations and to complicate the observed frequency response with multiple peaks.

The Refrigerant Database is an information system on alternative refrigerants, associated lubricants, and their use in air conditioning and refrigeration. it consolidates and facilitates.access to property, compatibility, environmental, safety, application and other information. It provides corresponding information on older refrigerants, to assist manufacturers and those using alternative refrigerants, to make comparisons and determine differences. The underlying purpose is to accelerate phase out of chemical compounds of environmental concern.
