20130130529 | Flexible Sealing Connector - A flexible sealing connector for conveying an electrical signal from a first tool portion to a second tool portion, at least one of the first tool portion and the second tool portion having a receiver with a surface defining a receiver passageway, includes a deformable boot in sealing engagement with the surface of the receiver passageway, the deformable boot having a surface defining a boot passageway. The connector further includes an electrical coupler in sealing engagement with the surface of the boot passageway, the coupler having a first end electrically connected to a first electrical line extending from the first tool portion and a second end electrically connected to a second electrical line extending from the second tool portion whereby the first line and the second line are electrically connected, the receiver passageway is sealed by the boot and the boot passageway is sealed by the coupler. | 05-23-2013 |
20130126245 | Annular Disposed Stirling Heat Exchanger - Apparatus and method for cooling internal components of a down-hole well drilling apparatus. Components of the well drilling apparatus are encased in an inner canister that is further encased in an outer canister creating a void between the inner canister and the outer canister. Further, a plurality of moveable barriers is disposed between the inner canister and the outer canister and contains a heat transfer fluid. A plurality of agitators add mechanical energy to the plurality of moveable barriers compressing and expanding, while repositioning, the heat transfer fluid and creating a heat pump based on a reverse Stirling cycle to remove heat from the cooler inner canister and transfer the heat to the hotter environment outside the outer canister. | 05-23-2013 |
20130119995 | Rugged Three-Axis Inclinometer - A method and apparatus for a rugged three-axis inclinometer for determining an object's orientation with respect to a gravitational field. Components of the apparatus include but not limited to a magnet, a non-magnetic casing, a ferrofluid, one or more non-magnetic gravitational field aligning materials attached to the magnet and a plurality of angle sensors attached to the non-magnetic casing. In this regard, when the apparatus is rotated, the gravitational field aligning materials maintain a constant orientation of the magnet and the angle sensors experience different magnetic field strengths as they rotate around the magnet. The position of the apparatus, with respect to the gravitational field can then be calculated based on the angle sensor outputs. | 05-16-2013 |

20130026355 | NEUTRON POROSITY MEASUREMENT DEVICES WITH SEMICONDUCTOR NEUTRON DETECTION CELLS AND METHODS - A neutron porosity measurement device adapted to receive a neutron source configured to emit neutrons having a first energy includes a segmented semiconductor detector located at a predetermined distance from the neutron source. The segmented semiconductor detector includes a plurality of semiconductor neutron detection cells configured to detect neutrons having a second energy smaller than the first energy. The cells are arranged in subsets located between a first distance and a second distance from the neutron source, each subset including semiconductor neutron detection cells surrounding an axis and being disposed in opposite sectors defined relative to the axis at substantially same distance from the neutron source. One or more of the neutron detection cells are configured to acquire data related to detected neutrons independently from one or more other of the neutron detected cells. A method of manufacturing the neutron porosity measurement device is also provided. | 01-31-2013 |
20120152518 | Low-Profile Suspension of Logging Sensor and Method - Presented are systems and methods for dampening vibrations transmitted to a sensor assembly based on well drilling operations. Vibration isolators are distributed around a sensor assembly and retained in their desired location. The sensor assembly and retained vibration isolators are inserted in a shrinkable thin-walled tube and the thin-walled tube is shrunk to constrict the inner surface of the thin-walled tube, and the retained vibration isolators against the outer surface of the sensor assembly. Additionally, the constricted thin-walled tube restrains a wiring harness associated with the sensor assembly in a wire well traversing the axial direction of the sensor assembly. | 06-21-2012 |
20120132439 | MULTIFUNCTION DOWNHOLE RELEASE TOOL MECHANISM WITH LOST MOTION - Presented is a system and method for disconnecting a plurality of wireline tools from a string of wireline tools while maintaining operation of the wireline tools remaining with the string of wireline tools. The disconnection is non-destructive and allows a reconnection of the disconnected tools after retrieval from the well. The system also enables testing of the disconnection mechanism before deploying the wireline tool string into the well. | 05-31-2012 |
20080306692 | Method and Apparatus for Determining the Permeability of Earth Formations - A method and apparatus for determining the fluid permeability of an earth formation is described. An instrument comprising an acoustic source and acoustic and electrokinetic sensors is located in a borehole at a site of interest. The acoustic source is fired and the resulting variations in pressure and electric field generated are measured and recorded. The Biot equation, and an equation for the streaming potential coupled to fluid displacement terms, is solved using finite element analysis to give an expected pressure waveform and electrokinetic waveform based on estimated earth formation properties. By comparison of the measured waveforms and those calculated from the equations, the actual permeability of the earth formation can be deduced. | 12-11-2008 |
