Development of core analysis procedures using x-ray computerized tomography

In a letter from John C. Lorenz of Sandia National Laboratories dated November 8, 1988, analyses of interest included. With the core received, measurements are not possible. Core must be loaded into a passive vessel to flow various fluids for permeability measurements. Because the core was slabbed and plugged, this was not possible. Microfractures or porosity distribution can also be seen by flowing two fluids with contrasting attenuation coefficients and using a subtractive imaging technique. This again could not be done because core could not be inserted into a flow vessel. Similarly, fracture interconnections could not be measured. Each cross-sectional computerized tomography image is made up of a 256 {times} 256 array of data. This data array is composed of CT numbers which are collected from the scanner. These CT numbers are defined as normalized attenuation coefficients for the material being scanned. At the energy level used for this data, the CT numbers are approximately proportional to the density of the sample material. Subsequently, colors are, assigned arbitrarily to the CT numbers to highlight contrasts in density in the core. Red is assigned to higher-density regions and blue to lower density regions. Variations from red to blue are shown in …

Preconstruction of the Honey Lake Hybrid Power Plant: Final report (open access)

Preconstruction of the Honey Lake Hybrid Power Plant: Final report

The work undertaken under this Contract is the prosecution of the preconstruction activities, including preliminary engineering design, well field development, completion of environmental review and prosecution of permits, and the economic and financial analysis of the facility. The proposed power plant is located in northeastern California in Lassen County, approximately 25 miles east of the town of Susanville. The power plant will use a combination of wood residue and geothermal fluids for power generation. The plant, when fully constructed, will generate a combined net output of approximately 33 megawatts which will be sold to Pacific Gas and Electric Company (PGandE) under existing long-term power sales contracts. Transfer of electricity to the PGandE grid will require construction of a 22-mile transmission line from the power plant to Susanville. 11 refs., 12 figs., 4 tabs.

Rawlins UCG Demonstration Project. Final technical progress report, May 10, 1988--August 9, 1988

The US Department of Energy and Energy International, Inc. have entered into a Cooperative Agreement to conduct a cost-shared field test demonstrating the operation of commercial-scale steeply dipping bed underground coal gasification (UCG) modules to provide the synthesis gas for a small-scale commercial ammonia plant. The field test and the commercial ammonia plant will be located near Rawlins, Wyoming. During this demonstration test, two or more modules will be operated simultaneously until one module is completely consumed and an additional module is brought on line. During this period, the average coal gasification rate will be between 500 and 1,200 tons per day. A portion of the raw UCC product gas. The UCG facility will continue to operate subsequent. to the demonstration to provide feedstock for the commercial plant. Energy International is responsible for accomplishing specific objectives in accordance with the Statement of Work by designing, installing, operating and monitoring the performance of the UCG modules as the feedstock source for the small-scale commercial ammonia plant. During this period, the project activities focused on project structuring, financing, and project management activities. Because the negotiations with investors were not completed on the schedule anticipated, adjustment of the schedule and activities was necessary. …
