  • In this study, the authors show that the mass spectrometric composition of coal tars can be predicted from the pyrolysis mass spectra of their parent coals. Curie-point low voltage electron ionization mass spectrometry (CuPy-EIMS) was performed on nineteen coals and on their respective pyrolysis liquids prepared by means of a fixed bed reactor method described elsewhere. Using factor and discriminant analysis techniques, the spectra can be classified and underlying structural variables responsible for the above classification identified. Furthermore, compositional similarities and dissimilarities between the solid samples and their liquids can be brought out using canonical correlation methods. Table I listsmore » the samples, their PSOC numbers, geological origin and the rank information. Of the nineteen coal samples, two are of subbituminous rank, three of high volatile B and C bituminous rank and the remainder of high volatile A bituminous rank. Twelve coals are from the Eastern/Appalachian coal province, six are from the Interior province and one is a Western coal from the Northern Great Plains province.« less
  • Elastic moduli of 15 cores were determined in the laboratory under simulated formation pressure and compared to the elastic moduli as determined from the 3-D velocity log run in the field. The laboratory system used enabled the compressional and shear velocities of the rock samples to be measured sequentially under triaxial pressure. The core samples were from 11 wells from different areas of the country representing a number of differing competent rock types. The ratio of compressional wave velocities measured in the field and the laboratory varied from 0.94 to 1.13 and the ratio of the shear wave velocities measuredmore » in-situ and in the laboratory varied fom 0.92 to 1.16. The elastic moduli computed from theoretical relations developed for homogeneous, isotropic, and elastic materials also indicated good agreement between the two sources of measurement indicating that the 3-D velocity system can provide in-situ measurements with sufficient accuracy to be of practical field use. Young's Modulus and Shear Modulus were related to both the compressional and shear wave velocities. The correlations developed allow both moduli to be predicted from knowledge of either the compressional or shear wave velocity. A proposed rock classification method is prepared relating Young's Modlus and rock density. Using measurements from 3-D velocity and density logs, sufficient information can be obtained to apply the rock classification system.« less
  • Petroleum explorationists are often faced with determining the relationship between the products of wells completed in lithologies that may have some spatial or communicative relationship. Conventional methods of sampling and analysis are often time consuming and expensive. A new method for the sampling, analysis, and computerized data interpretation of the C2-C16 fraction of crude oil and natural gas is reported here. Controlled temperature headspace sampling of crude oils and direct pressure equilibrated natural gas exposure of carbon adsorption wires has been successfully applied to the sampling of the volatile fractions of petroleum fluids. Thermal vacuum desorption followed by mass spectrometricmore » analysis of these volatile organic compounds is a rapid and sensitive method for obtaining detailed information of the distribution (fingerprint) of the components in a given sample; however, the resulting information is too complex for direct human interpretation. Techniques of computerized chemical pattern recognition such as principal components analysis (PCA) with graphical rotation, discriminant analysis, and similarity analysis (SIMCA) have proven useful in establishing the relationships between potentially correlated samples via the fingerprints of their volatile fractions. Studies have been conducted on multiple samples from numerous continental basins. The results of several of these studies will be presented to demonstrate the applicability of this new, rapid, cost-efficient approach to correlation studies.« less
