Automated volume saving liquid exchange device in a single rotating cylinder
The present invention provides a device and a method for automated liquid exchange in a horizontally rotating container that may be applied in automated sample treatment by using chemical solutions, in sequential order. Such applications include biomolecule staining on solid support or fixed samples such as western blot or tissue slice processing.

A method of determining fluid inflow rates within a wellbore comprises determining a plurality of temperature features from a distributed temperature sensing signal originating in a wellbore, determining one or more frequency domain features from an acoustic signal originating the wellbore, and using at least one temperature feature of the plurality of temperature features and at least one frequency domain feature of the one or more frequency domain features to determine a fluid inflow rate at one or more locations along the wellbore. |

Iterative borehole correction
Raw signal measurements can be received by sensors in a wellbore. Borehole effects can affect the raw signal measurements. The raw signal measurements can be converted into ratio signals having attenuation and phase shift. An apparent resistivity can be determined from the ratio signals. Mud resistivity can be determined based on apparent resistivity, at least part of the raw signal measurements, and the borehole size. A true resistivity can be determined based on the mud resistivity and at least part of the ratio signals. The raw signal measurements and the ratio signals can be updated based on the true resistivity. Steps can be repeated to determine a corrected true resistivity. Based on the true resistivity value and updated raw signal measurements and ratio signals, an operating characteristic of a well tool can be caused to be adjusted. |

Multi-frequency acoustic interrogation for azimuthal orientation of downhole tools
An apparatus for detecting a location of an optical fiber having an acoustic sensor disposed subsurface to the earth includes an acoustic emitter configured to emit a first signal having a first frequency and a second signal having a second frequency that is higher than the first frequency, the first and second emitted acoustic signals being azimuthally rotated around the borehole and an optical interrogator configured to interrogate the optical fiber to receive an acoustic measurement that provides a corresponding first received signal and a corresponding second received signal. The apparatus also includes a processor configured to (i) frequency-multiply the first received signal to provide a third signal having a third frequency within a selected range of the second frequency, (ii) estimate a phase difference between the second received signal and the third signal, and (iii) correlate the phase difference to the location of the optical fiber. |

Method of drilling a wellbore to a target
A method of drilling a wellbore to a target includes measuring attitudes at two adjacent survey stations along a wellbore using a downhole surveying tool. An actual change in wellbore position over a survey leg linking the two survey stations is determined. Corrections are applied to the measured attitude at one or both of the survey stations such that a modeled well path joining the survey stations reflects the determined actual change in wellbore positon between the two survey stations. |

Downhole 3D geo steering viewer for a drilling apparatus
Systems, devices, and methods for producing a three-dimensional visualization of one or more of a drilled wellbore, a bottom hole assembly, a drill bit, a drill plan, and one or more lithology windows is provided for drill steering purposes. A drilling motor with a toolface in communication with a sensor system is provided. A controller in communication with the sensor system is operable to generate a depiction of the drill plan, a depiction of the drilling motor, and one or more lithology windows, and to combine these depictions in a three-dimensional visualization of the down hole environment. This visualization may be used by an operator to steer the drilled wellbore. |

Down-hole gas separator
A method and apparatus for gas and solids separation from down-hole fluids is disclosed, including particular structural means for forcing the de-gassing of the gaseous liquid, including means for changing the velocity of the gaseous liquid (speed changes on each exit from the tubes owing to the volume difference between the tubes and the chamber), means for changing the direction of the gaseous liquid (owing to the flow changing direction from exiting one set of tubes to travel to the opening to enter the next set of tubes), and means for changing the pressure of the gaseous liquid (owing perhaps in part to evolution of gas upon entering increased volume). |

Selective heating of fluid components with microwaves to change viscosity ratio in downhole fluid devices
An apparatus for processing components of a fluid having a first fluid component and a second fluid component in a fluid property-dependent fluid device includes an energy device configured to input energy to the fluid, the energy selectively changing a property of one of the first and second components more than the other of the first and second components. |
