Abstract:
Total porosity of impregnated thin sections can be measured using X-ray fluorescence. The technique requires an impregnating fluid which contains an element not contained in more than trace quantities by the rock. By measuring the intensity of fluorescence generated by bombarding the impregnated thin section with sufficiently energetic X-rays and rationing that intensity to the intensity of fluorescence generated by subjecting a sample containing only epoxy to the same conditions, and scaling the resulting measures of fluorescence, a measure of total effective porosity is produced.
Abstract:
The high temperature strength to density ratio of titanium aluminum niobium alloys of the Ti.sub.3 Al (alpha two) type is increased when molybdenum is added. New alloys contain by atomic percent 25-27 aluminum, 11-16 (niobium+molybdenum), 1-4 molybdenum, balance titanium. When vanadium replaces up to 3.5% molybdenum a lighter weight alloy is produced. The new alloys have higher elastic modulus and higher creep strength to density ratio than alloys without molybdenum.
Abstract:
Improved refractories for resisting attack of molten titanium aluminum and similar metals are provided by the inclusion of sulfur. Metal, oxygen, and sulfur combinations, wherein sulfur is present at from 10 to 60 atomic percent, are particularly useful.Disclosed is a material having the atomic formula M.sub.a S.sub.b O.sub.c where O is oxygen, S is sulfur, and M is at least one metal selected from the scandium subgroup of the periodic table transition metals (scandium, yttrium and the rare earths) and aluminum. In an alternate material, M is comprised of at least two elements, the first selected as above and the second selected from the alkaline earth metal group. A preferred material is formed by mixing and firing CaS and Y.sub.2 O.sub.3 in proportions which results in (Ca+Y).sub.0.43 S.sub.0.14 O.sub.0.43.
Abstract:
Provided herein are methods for identifying a region of a geologic area comprising a fault or other feature associated with a pressure loss. Such methods can comprise (1) subjecting rock samples from separated sites in an area to condition(s) that can cause the release of carbon dioxide (CO2), one or more volatile carbon dioxide-related, or both, if present, while not causing the release of a significant amount of CO2 or the one or more CO2-related compounds associated with the crystalline structure of the material, (2) measuring the amount of CO2, the one or more related compounds, or both, and (3) identifying regions in the geologic area associated with a relatively low CO2, related compounds, or both, or similar or alternative methods involving the analysis of such compositions associated with materials provided here.
Abstract:
The invention described here provides new methods of analyzing materials, e.g., geologic materials, to identify wettability characteristics of such materials. Methods of the invention comprise analyzing the amount of easily extracted water obtained from samples of a material, such as a geologic area, analyzing release resistant water obtained from such samples or co-located samples, and/or optionally calculating or analyzing the combined water in or obtained from such samples, and utilizing such values alone or in comparison to one another to assess the wettability characteristics of the material.
Abstract:
Provided herein are methods of characterizing rock qualities, such qualities of rock obtained as cuttings from petroleum operations. One embodiment comprises determining the carbonate grain size of one or more rock samples by subjecting the samples to conditions that cause release of carbon dioxide or carbon dioxide-related compound(s) and quantifying the amount thereof. In another embodiment, the invention provides a method of identifying regions of a geologic area likely to be associated with faults by identifying regions of low carbon dioxide or other target volatile compound(s) compared with expected properties and/or the surroundings of the low volatile compound region. Other methods involve analyzing differences in the amounts of compounds of different sizes in different geologic areas. The methods can aid in guiding petroleum exploration and/or production operations.
Abstract:
A mold (form) in which an endotracheal tube, having a stylette therein, is received so as to form the overall configuration of the endotracheal tube is disclosed. The mold has a recess in the surface thereof to receive the endotracheal tube with a stylette therein. The recess has a curve therein adjacent one end of the mold to receive the distal end of the endotracheal tube. The recess in the opposite end of the mold has a bend therein to receive the proximal end of the endotracheal tube. The recess in the intermediate portion of the mold is substantially straight and interconnects the curved end and the oppositely disposed bent end of the recess. The stylette is fabricated from a thin metallic malleable rod which is bendable, and thus configurable, to retain the overall configuration of the endotracheal tube after being formed and removed from the mold. The stylette is withdrawn from the endotracheal tube after the distal end thereof has been inserted through the vocal cords and just into the trachea of the patient being intubated. Due to the configuration of the endotracheal tube, withdrawal of the stylette causes the distal end of the tube to advance further into the trachea of the patient being intubated.

Abstract:
The method employs standard processing techniques in order to derive and maintain raw data as well as background corrected and shop calibrated data. Specific data from standard processing is used for the Enhanced Vertical Resolution (EVR) processing. The method uses corrected and calibrated data from standard processing. This data is filtered using improved standard processing material matching filters. Density correction factors .DELTA..rho..sub.LONG (or equivalently .DELTA..rho..sub.SHORT) is calculated for the long and short detectors and used in further processing. .DELTA..rho..sub.LONG and .DELTA..rho..sub.SHORT are used to calculate the standard calibrated compensated density .rho.. Enhanced processing begins with the iterative deconvolution and filtering (or smoothing) of .DELTA..rho..sub.SHORT. The background corrected and shop calibrated short density data, calculated during standard processing, is materially matched using an improved EVR filter. Finally, an enhanced calibrated borehole compensated density .rho..sub.B is calculated. The use of the same processing methods and a strict enforcement of material matching, both for the standard and enhanced processing, insures that neither short nor long detector count rates are overemphasized and that shop calibrations and borehole compensation are accurately maintained.
