Patent number: 4476391Abstract: A method for improving the accuracy of neutron detectors is disclosed wherein a predetermined threshold level, by analysis of a neutron and gamma relative distribution curve, is set and all amplitudes below this predetermined minimum are removed from a neutron detector total count.Type: GrantFiled: March 8, 1982Date of Patent: October 9, 1984Assignee: Mobil Oil CorporationInventor: Adam Bednarczyk
-
Patent number: 4476551Abstract: In seismic exploration a method for improving seismogram displays is disclosed wherein seismograms having an offset which produces poor signal power are muted and seismograms having offsets with high signal power are stacked. The signal power in a CDP set is determined as a function of different values of assumed acoustic velocity of the earth. This signal detection is repeated for successive values of travel time and offset. The maximum signal power is plotted for values of velocity as a function of travel time and for different ranges of offset to form contours of the maximum signal power as a function of time and offset.Type: GrantFiled: December 31, 1980Date of Patent: October 9, 1984Assignee: Mobil Oil CorporationInventor: William H. Ruehle

Bowden, Robert V. Przybyl
-
Patent number: 4473800Abstract: A method for removing the effects of said subsurface anomalies in magnetotelluric survey data is disclosed wherein resistivity curves are compared and a correction factor is determined. Resistivity curves having a deviation from a mean are multiplied by this correction factor.Type: GrantFiled: September 21, 1982Date of Patent: September 25, 1984Assignee: Mobil Oil CorporationInventor: Barry N. Warner
-
Patent number: 4465094Abstract: An apparatus is provided wherein one air supply is used to supply compressed air for a plurality of multi-size seismic pulse generators.Type: GrantFiled: January 13, 1982Date of Patent: August 14, 1984Assignee: Mobil Oil CorporationInventors: Donald F. Huffhines, Robert E. Roach
-
Patent number: 4422164Abstract: An ocean bottom seismometer unit records refraction waves from a seismic source. The refraction waves are digitzed and stored in a magnetic memory. Periodically, a tape recorder is started and digital samples are transferred from digital memory to tape during a time in which operation of the tape recorder will not generate spurious noise signals which interferes with the detection of the refraction waves. The water break is detected and the time of its occurrence is digitized. Only the digitized time of the water break occurrence is recorded thereby permitting shortened record length and increased record storage capacity.Type: GrantFiled: June 27, 1980Date of Patent: December 20, 1983Assignee: Mobil Oil CorporationInventors: Edgar A. Bowden, Gordon R. Deline, Gerard D. Koeijmans
-
Patent number: 4385021Abstract: A method is disclosed for structuring a plurality of supply and control conduits having a length substantially greater than its cross sectional width wherein the control conduits for each supply conduit are segregated and covered. The segregated and covered control conduits are bundled in a generally annular shape and the supply conduits are placed around the control conduits in a generally circular fashion. The entire bundle is then covered to retain its circular shape by periodically fastening the resultant bundle circumferentially or by extruding a covering over its entire length.Type: GrantFiled: July 14, 1981Date of Patent: May 24, 1983Assignee: Mobil Oil CorporationInventor: Walter P. Neeley
-
Patent number: 4382486Abstract: The present invention provides a method for determining the spacing and size of air guns in a tuned air gun array. Volume ratios are calculated based upon a predetermined maximum volume for any individual air gun. The volumes are cross-referenced to spacings for optimum air gun interaction. The resulting air gun array operates as a broadband high-energy point source.Type: GrantFiled: February 5, 1981Date of Patent: May 10, 1983Assignee: Mobil Oil CorporationInventor: William H. Ruehle
-
Patent number: 4312049Abstract: A method of logging a wellbore to identify oil, gas and water zones in a hydrocarbon-bearing formation that is characterized by acoustic velocities which are maximum when saturated with oil, minimum when saturated with water and intermediate when saturated with gas. The formation is logged with a sonic logging system utilizing a frequency within the range of 0.1 to 10 KHz and logged with a lithologic logging system to account for variations in lithology on the sonic log. Thereafter the sonic log is compared with the known acoustic velocity characteristic of the hydrocarbon-bearing formation to identify the oil, gas and water zones therein.Type: GrantFiled: October 29, 1979Date of Patent: January 19, 1982Assignee: Mobil Oil CorporationInventors: Lucien Masse, W. Louis Medlin, James H. Sexton

Patent number: 4266188Abstract: A method and apparatus for measuring the concentration of a particular component, e.g. water, in a two-component mixture, e.g. water-oil. A probe having three sets of sensor electrodes is positioned into the mixture. A first elastic sac is secured over the exposed ends of a first set of electrodes and is filled with water. A second elastic sac is secured over the exposed ends of a second set of electrodes and is filled with oil. The ends of the third set of electrodes are left exposed. The electrodes are energized and each generate a signal representative of a measured electrical property, e.g. resistivity, conductivity, or capacitance, of the liquid in which they are immersed. By properly combining these three signals, the concentration of the particular component is determined.Type: GrantFiled: November 30, 1979Date of Patent: May 5, 1981Assignee: Mobil Oil CorporationInventor: Francis Thompson

Patent number: 4148211Abstract: In apparatus for analyzing the exhaust gas of a motor vehicle, the apparatus including an oxygen sensor and means for sampling a portion of the exhaust gas and conducting the sample to the sensor, there is disclosed an improvement wherein the exhaust gas is used to heat a moisture barrier and the oxygen sensor and is then cooled before being directed through the moisture barrier to the sensitive area of the oxygen sensor. This arrangement prevents moisture from condensing on the sensitive area of the oxygen sensor, which moisture would interfere with the operation of the sensor.Type: GrantFiled: March 22, 1978Date of Patent: April 10, 1979Assignee: Beckman Instruments, Inc.Inventors: Kenneth B. Sawa, Willis M. Peek, John D. Blanke

Patent number: 4144482Abstract: A brake circuit for a universal motor having an armature and a field winding normally connected in series therewith, the circuit including switch means operable to disconnect the power source and electrically connect the armature in series with the field winding and a brake resistor, with voltage limiting means in parallel with the field winding. The voltage limiting means include biasing diodes for maintaining the voltage across the field generally constant, resulting in a more even deceleration rate and a lower total brake time.Type: GrantFiled: April 7, 1977Date of Patent: March 13, 1979Assignee: Beckman Instruments, Inc.Inventor: Christopher M.
