IN MANY FLUID INJECTION PROCESSES USED FOR OIL RECOVERY, SUCH AS WATERFLOODING, THE INJECTED FLUIDS FLOW PREFERENTIALLY THROUGH THE ROCK ZONES OF HIGH FLOW CAPACITY (HIGH PERMEABILITY), BYPASSING OIL THAT IS PRESENT IN THE TIGHTER PARTS OF THE RESERVOIR ROCK. THIS MAY RESULT IN HIGH WATER-TO-OIL-PRODUCING RATIOS AND ABANDONMENT OF A PROJECT AT A RELATIVELY LOW VOLUMETRIC SWEEP EFFICIENCY. ONE APPR ...

BECAUSE OF THEIR LONG DECAY TIMES, SCINTILLATORS IN NEUTRON LOGGING TOOLS ARE RESPONSIVE PRIMARILY TO THE GAMMA RADIATION FROM THE NEUTRON CAPTURE SPECTUM. THIS INHIBITS POROSITY MEASUREMENTS IN GAS-FILLED ZONES AND SUBSTANTIALLY LIMITS THE ELEMENTAL INFORMATION ON THE STRATA WHICH CAN BE ACQUIRED. ADVANCES IN NEUTRON LOGGING TOOLS REQUIRE A NEW SCINTILLATOR MATERIAL CAPABLE OF MAKING PRECISION ME ...

WE DESCRIBE A NOVEL LEAK DETECTOR FOR XENON THAT HAS DIRECT APPLICATION TO TESTING RADIO-ISOTOPE-POWERED THERMOELECTRIC GENERATORS. SUCCESSFUL DEMONSTRATION OF OUR INNOVATION WILL ALLOW IMPROVED EFFICIENCY IN THERMOELECTRIC GENERATORS BY REMOVING THE HELIUM THAT IS NOW ADDED TO THE XENON BUFFERGAS FOR LEAK CHECKING PURPOSES. THE PHASE I RESEARCH PROGRAM WILL PROVIDE THE CRITICAL DESIGN INFORMATION ...

AN INSTRUMENT IS UNDER DEVELOPMENT THAT WILL QUANTITATIVELY MEASURE ISOTOPIC RATIOS ON A SOLID OR LIQUID SURFACE OF URANIUM (OR OTHER ELEMENTS). THE INSTRUMENT USES A PULSED ION BEAM AT GRAZING INCIDENCE TO KNOCK SURFACE ATOMS OFF IN BILLIARD BALL TYPE COLLISIONS. SOME OF THESE ATOMS ARE IONIZED AND CAN BE FOCUSED THROUGH A HIGH RESOLUTION TIME-OF-FLIGHT MASS SPECTROMETER. A HIGH DUTY CYCLE ALLOWS ...

EXISTING INSTRUMENTATION FOR CHEMICAL ANALYSIS OF GAS MIXTURES DO NOT PROVIDE THE CAPABILITY FOR REAL-TIME MEASUREMENT OF A BROAD RANGE OF SPECIES AT TRACE (PPB) CONCENTRATION LEVELS. SUCH A CAPABILITY IS IMPORTANT IN MANY APPLICATIONS IN ATMOSPHERIC RESEARCH, POLLUTION CONTROL, TOXIC GAS SENSING, AND INDUSTRIAL PROCESS MONITORING. ALTHOUGH SPECIALIZED LASER METHODS HAVE BEEN DEMONSTRATED FOR MEAS ...
