Abstract: Method and apparatus are provided for analyzing closely adjacent minerals in specimens of naturally occuring minerals. A sectioned mineral sample is mounted on a glass slide and placed in a vacuum chamber. An optical microscope is used to examine the sample through a window in the vacuum chamber. A laser beam is used for pyrolyzing a portion of the specimen causing gases to be released. Gases released from the mineral are analyzed by a mass spectrometer. Relative movement of the sample and laser beam, pyrolysis of target samples, and analysis of released gases can be automated.

Abstract: A simultaneous pulsed neutron porosity and thermal neutron capture cross section logging system is provided in the present invention. A logging tool provided with a 14 MeV pulsed neutron source, an epithermal neutron detector, and a combination gamma ray and fast neutron detector is moved through a borehole. Repetitive bursts of neutrons irradiate the earth formations and, during the bursts, the fast neutron and epithermal neutron populations are sampled. During the interval between bursts the thermal neutron capture gamma ray population is sampled in two or more time intervals. The fast and epithermal neutron population measurements are combined to provide a measurement of formation porosity .phi.. The capture gamma ray measurements are combined to provide a simultaneous determination of the thermal neutron capture cross section .SIGMA..

Abstract: An improved measurement of earth formation porosity is provided by the present invention using measurements of the energy spectrum of fast neutrons. A continuous source of fast neutrons is used to irradiate earth formations penetrated by a well borehole. Two neutron detectors, a fast neutron detector sensitive in the high energy range of the fast neutron energy spectrum, and an epithermal neutron detector, sensitive in the lower energy range of fast neutrons, are spaced at the same effective distance from the neutron source. Measurements of the neutron population at each detector are combined according to predetermined relationships to derive a measurement of earth formation porosity.

Abstract: A fast neutron source is used to irradiate earth formations in the vicinity of a well borehole. Dual spaced epithermal neutron detectors are used to sample the epithermal neutron population at two different spaced distances from the source. A compensated formation porosity is obtained from the ratio of counting rates at the dual spaced detectors. An uncompensated porosity value is obtained from the count rate at the short spaced detector. Borehole washout or cement void regions are located by comparing the compensated and uncompensated values of formation porosity obtained in this manner.
