Abstract: The present disclosure is for a tool for measurement of phases in fluid in downhole applications. The tool includes a light coupler for providing a first light and for detecting a second light. The first light is provided to an optical interface and the second light is received from the optical interface. The optical interface is between the tool and the fluid. An optical path is provided that is integral or coupled to the optical interface. The optical path allows transmission of the first light into the fluid at the optical interface and also allows receiving the second light from the optical interface. The second light includes one or more light components disturbed by the fluid. A processor provides digital data associated with the measurement of phases in the fluid using optical data from at least the second light.

Abstract: Embodiments of the present disclosure include a system for driving an arm radially outward from a work string axis including a pivot block coupled to the arm at a first coupling, the arm rotating about the first coupling in a first direction to move from a stored position to an expanded position, and about the first coupling in a second direction to move from the expanded position to the stored position. The system also includes a biasing member that drives movement of the arm in the first direction. The system further includes a chamber for storing the biasing member within a pivot block diameter when the arm is in the stored position.

Abstract: A peak hold circuit configured for use in a downhole sensor includes a long tail pair circuit, a correction circuit, and a current mirror circuit. The current mirror circuit includes two current mirrors connected to a long tail pair formed by a first transistor and a second transistor. The current mirror also includes a first resistor and a second resistor connected to a third transistor. The first transistor is connected to a correction transistor of the correction circuit. The value of the first resistor is selected to be essentially equal to the same value as the second resistor so that when the long tail pair is balanced, the current flowing through a collector of the second transistor is equal to the current flowing through the first transistor, causing the correction transistor to switch off.

Abstract: 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.

Abstract: 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.
