20130301052 | TEMPERATURE CALIBRATION METHODS AND APPARATUS FOR OPTICAL ABSORPTION GAS SENSORS, AND OPTICAL ABSORPTION GAS SENSORS THEREBY CALIBRATED - An optical absorption gas sensor has an LED light source and a photodiode light detector, a temperature measuring device for measuring the LED temperature and a temperature measuring device for measuring the photodiode temperature. The sensor is calibrated by measuring the response of photodiode current at zero analyte gas concentration and at a reference analyte gas concentration. From these measurement, calibration data taking into account the effect of photodiode temperature on the sensitivity of the photodiode and, independently, the effect of changes in the spectrum of light output by the LED on the light detected by the photodiode with LED temperature can be obtained. Calibration data is written to memory in the gas sensor and in operation of the gas sensor, the output is compensated for both LED and photodiode temperature. The LED and photodiode can therefore be relatively far apart and operate at significantly different temperatures allowing greater freedom of optical pathway design. | 11-14-2013 |

20130026369 | GAS SENSOR WITH RADIATION GUIDE - An optical absorption gas sensor includes a radiation source, detector and a radiation guide. The radiation source and detector are close together and in thermal communication. The radiation guide has a rectangular cross section and curves in a first sense, around an axis parallel to the major dimension of the rectangular cross section, and then in a second opposite sense, and again in the first sense. A relatively long path for radiation is provided in a compact device, without the attenuation of radiation which would occur if the radiation guide did not have a rectangular cross section and curved only around an axis parallel to the major dimension of the rectangular cross section. A reference measurement can be obtained by mounting a reference radiation source behind a translucent measurement radiation source and directing radiation from the reference radiation source through the measurement radiation source. Radiation from a reference radiation source may be directed around the measurement reference source. Measurement and reference signals can be obtained by using a light emitting diode to generate radiation which is detected by a photodiode, in a first operating mode, and driving the photodiode to generate radiation having a different emission spectrum while detecting the resulting radiation using the light emitting diode, in a second operating mode. An optical absorption gas sensor may be manufactured by abutting two or more L-shaped radiation guide portions to form a radiation guide. The radiation guide has an interior surface operable to reflect radiation emitted by the radiation source of the optical absorption gas sensor. | 01-31-2013 |

20080309346 | ELECTROMAGNETIC DETECTOR FOR MARINE SURVEYING - A detector for underwater electromagnetic surveying is described. The detector comprises first, second, third and fourth electrodes which are arranged to define first, second and third electric dipole antennae extending between pairs of the electrodes. Each dipole antennae extends between a pair of the electrodes and the fourth electrode is common to all three dipole antennae. Thus the first electrode is separated from the fourth electrode along a first direction to provide the first dipole antenna, the second electrode is separated from the fourth electrode along a second direction to provide the second dipole antenna, and the third electrode is separated from the fourth electrode along a third direction to provide the third dipole antenna. The electrodes are arranged so that the first, second and third directions are inclined at an angle of between 20 and 70 degrees to a surface on which the detector rests when in normal use. | 12-18-2008 |
20090082970 | Electromagnetic Surveying - A method of analysing results from an electromagnetic survey of an area that is thought or known to contain a subterranean resistive or conductive body within a background strata configuration is described. The method comprises providing a set of electromagnetic field data obtained using at least one electromagnetic receiver and at least one electromagnetic source for a range of source-receiver separations, e.g. providing conventional controlled-source electromagnetic survey data. A subset of the electromagnetic field data is identified that comprises data obtained for source-receiver separations greater than a selected threshold offset. The threshold offset is chosen so that data beyond this offset are characteristic of magnetotelluric data. Thus the subset of data is then processed in accordance with a first technique to obtain information on the background strata configuration. Other electromagnetic field data obtained for source-receiver separations less than the threshold offset may then be processed in accordance with a second technique to obtain information on any subterranean resistive or conductive body within the background strata configuration. | 03-26-2009 |
20090306895 | GEOPHYSICAL SURVEYING - A method of analysing controlled source electromagnetic (CSEM) survey data to determine probability density functions (PDFs) for values of an electromagnetic parameter at locations in a subterranean region of interest is provided. Structural features in the subterranean strata are identified, e.g. from seismic survey data. An initial PDF for values of the electromagnetic parameter is then assigned to each feature. Models lo specifying values for the parameter in each structural feature are generated by sampling the PDFs. A subset of the models are deemed acceptable based on an acceptance criterion. The PDF for each feature is modified based on values for the parameter in the subset of accepted models to generate replacement PDFs for each feature. The process may be iterated a number of times to generate final PDFs for values of the electromagnetic parameter in the structural features identified in the subterranean region of interest. | 12-10-2009 |

20090039888 | ELECTROMAGNETIC SURVEYING FOR HYDROCARBON RESERVOIRS - A method of electromagnetic surveying of an area of seafloor that is thought or known to contain a subterranean hydrocarbon reservoir is described. The method includes broadcasting an EM signal from a horizontal electric dipole (HED) transmitter and obtaining vertical electric dipole (VED) response data at a remote receiver in response thereto. Survey data are analysed by comparing the VED response data with background data which are not sensitive to the postulated hydrocarbon reservoir. Accordingly, differences between the VED response data and the background data allow for the identification of buried hydrocarbon reservoirs. The background data may be provided by magneto-telluric surveying, controlled source electromagnetic surveying or from direct geophysical measurement. By employing VED response data in this way, surveys may be performed in shallower water than has previously been possible since the VED detector is not sensitive to air-wave components of the EM field induced by the HED transmitter at the VED detector. | 02-12-2009 |
