20090146837 | High Performance Communication system - A system for communicating information in a borehole between tool assemblies in a tool string includes receiving an information signal and separating a first signal that may be a power and low speed signal. A second signal is separated and demodulated from the information signal. The first signal and second signal are transmit to electronic devices that process data from an earth formation. After the first and second signals are transmit to one or more electronic devices, the signals are modulated and/or filtered and then combined into the information signal. The first signal is at one frequency and the second signal is at a different frequency. The apparatus includes a main signal line that couples to a second signal line and third signal line in the tool assembly. | 06-11-2009 |

20140299312 | ELECTRICAL ISOLATION OF SUBTERRANEAN CASING SECTION - A method and apparatus for electrically-enhanced oil recovery from an oil-bearing subterranean formation are provided. An isolation opening extends around the circumference of a casing to provide a separation of the inflow section from an adjacent section of the casing. A portion of the oil-bearing formation disposed on the outside of the isolation opening is removed to form a void in the oil-bearing formation adjacent the isolation opening. A material having less electrical conductivity than the casing is inserted into the void and the isolation opening to form an insulative barrier. | 10-09-2014 |
20140346324 | COMPENSATED OPTICAL DETECTION APPARATUS, SYSTEMS, AND METHODS - In some embodiments, apparatus and systems, as well as methods, may operate to receive radiation at an active detector of a pair of radiation detectors to provide a first signal proportional to an intensity of the radiation, to receive none of the radiation at a blind detector of the pair of radiation detectors to provide a second signal proportional to the reception of no radiation, and to combine the first signal and the second signal to provide an output signal representing the difference between the first signal and the second signal. The pair of radiation detectors may comprise thermopile detectors. Combination may occur via differential amplification. Additional apparatus, systems, and methods are disclosed. | 11-27-2014 |

20120211650 | Downhole Optical Radiometry Tool - Various methods and tools optically analyze downhole fluid properties in situ. Some disclosed downhole optical radiometry tools include a tool body having a sample cell for fluid flow. A light beam passes through the sample cell and a spectral operation unit (SOU) such as a prism, filter, interferometer, or multivariate optical element (MOE). The resulting light provides a signal indicative of one or more properties of the fluid. A sensor configuration using electrically balanced thermopiles offers a high sensitivity over a wide temperature range. Further sensitivity is achieved by modulating the light beam and/or by providing a reference light beam that does not interact with the fluid flow. To provide a wide spectral range, some embodiments include multiple filaments in the light source, each filament having a different emission spectrum. Moreover, some embodiments include a second light source, sample cell, SOU, and detector to provide increased range, flexibility, and reliability. | 08-23-2012 |
20130087723 | DOWNHOLE SOURCES HAVING ENHANCED IR EMISSION - Light sources are provided with enhanced low-frequency (e.g., near infrared) emission. Some disclosed embodiments include a filament and at least one re-radiator element. The filament heats the re-radiator element to a steady-state temperature that is at least one quarter of the filament's absolute temperature. As disclosed herein, the increased surface area provided by the re-radiator element provides enhanced IR radiation from the light source. Patterning or texturing of the surface can further increase the re-radiator element's surface area. Various shapes such as disks, collars, tubes are illustrated and can be combined to customize the spectral emission profile of the light source. Some specific embodiments employ a coating on the bulb as the re-radiator element. The coating can be positioned to occlude light from the filament or to augment light from the filament, depending on the particular application. The various re-radiator elements can be positioned inside or outside the bulb. | 04-11-2013 |
