Energy Program annual report

The national economy is particularly dependent on efficient electrical generation and transportation. Electrical demand continues to grow and will increasingly rely on coal and nuclear fuels. The nuclear power industry still has not found a solution to the problem of disposing of the waste produced by nuclear reactors. Although coal is in ample supply and the infrastructure is in place for its utilization, environmental problems and improved conversion processes remain technical challenges. In … more

Polysaccharides and bacterial plugging

Before any successful application of Microbial Enhanced Oil Recovery process can be realized, an understanding of the cells' transport and retentive mechanisms in porous media is needed. Cell transport differs from particle transport in their ability to produce polysaccharides, which are used by cells to adhere to surfaces. Cell injection experiments have been conducted using Leuconostoc cells to illustrate the importance of cellular polysaccharide production as a transport mechanism that hinde… more

Development and field testing of a process for recovering heavy crude oil in the Carlyle pool-Allen County, Kansas using the Vapor Therm generator. Final report

A Vapor Therm generator capable of producing steam and inert gases was built for conditions encountered in the Carlyle pool, and is capable of delivering heated gases at 900 psi and 700/sup 0/F. New wells were drilled in a five spot pattern with an inter-well distance of 208.7 ft. Logs and cores from these new wells were obtained and the subsurface reservoir was evaluated. Oil content of 1197 BSTO/Ac-Ft was encountered. This oil was 19.5/sup 0/ API with a viscosity of 1026 cps at 70/sup 0/F. Th… more

Identification of cross-formation flow in multireservoir systems using isotopic techniques

This study was designed to add quantitative solutions to the problem of undesirable hydraulic communication which results in active fluid flow between productive horizons. Transfer of novel geochemical methods, based on effective, economic, and environmentally acceptable isotopic techniques for identification of leaking hydrocarbon reservoirs, is a major objective of this study. The effectiveness of a continuous trap's seal depends on an equilibrium between the capillary forces holding formatio… more

Massive hydraulic fracturing well, Federal No. 498-4-1, Rio Blanco County, Colorado. Final report

This project is an MHF of a previously untreated Mesaverde interval in a well in northwest Colorado. The rocks involved may have been deposited during a marine invasion of long-continued, swamp environments. If so, they would have possessed superior primary reservoir properties. The logging program, identical to those used in the nearby Rio Blanco Nuclear and MHF Project wells, supplied contradictory information. The frac could furnish better understanding of the log suite, better parameters fo… more

Random choice method for calculating fluid displacement in a porous medium

Multiphase fluid displacement in a porous medium gives rise naturally to the occurrence of steep fronts, for example between different fluids or between regions of differing chemical concentrations. Such fronts pose substantial difficulty for most numerical methods. However, the recently developed random choice numerical method has been found capable of following effectively even perfectly sharp fronts. An application to the calculation of immiscible displacement in a petroleum reservoir is dis… more

Comparative evaluation of surface and downhole steam-generation techniques

It has long been recognized that the application of heat to reservoirs containing high API gravity oils can substantially improve recovery. Although steam injection is currently the principal thermal recovery method, heat transmission losses associated with delivery of the steam from the surface generators to the oil-bearing formation has limited conventional steam injection to shallow reservoirs. The objective of the Department of Energy's Project DEEP STEAM is to develop the technology requir… more
