Stress-Relief Displacements Induced by Drilling--Applications to Holographic Measurements of in Situ Stress

Description: The holographic stressmeter is an instrument which has been developed at Caltech to allow determination of the complete stress tensor from in situ borehole measurements. The stressmeter uses double-exposure holographic interferometry to record the displacements induced by the drilling of a small sidehole into the borehole wall. The local stresses, which are the result of the far-field stresses, concentrated at the borehole, cause deformation of the surface of the borehole wall in the vicinity o… more

Advanced coal-fueled gas turbine systems. Technical progress report, January--March 1992

Description: No combustion tests for this program were conducted during this reporting period of January 1 to March 31, 1992. DOE-sponsored slogging combustor tests have been suspended since December 1991 in order to perform combustion tests on Northern States Power Company (NSP) coals. The NSP coal tests were conducted to evaluate combustor performance when burning western sub bituminous coals. The results of these tests will guide commercialization efforts, which are being promoted by NSP, Westinghouse El… more

Development of improved iron Fischer-Tropsch catalysts. Quarterly technical progress report, 1 January 1992--31 March 1992

Description: Three tests (two fixed bed and one stirred tank slurry reactor) were completed during the reporting period. Also, the work on catalyst characterization by different techniques (atomic absorption, BET surface area and pore size distribution and x-ray powder diffraction).The performance of a precipitated iron catalyst with nominal composition lOOFe/0.3Cu/0.8K has been evaluated in two fixed bed reactor tests designated FB-0142 and FB-0352 following pretreatment with syngas (H{sub 2}/CO=0.67) at 2… more
