Abstract: A full bore spectral gas holdup tool that measures gas holdup that is corrected for effects of the flowstream lamination and the salinity of the liquid in the a flowstream. The basic methodology utilizes spectral data from two gamma ray detectors at different spacings from a nuclear source that emits gamma radiation. 57Co is the preferred source and the gamma ray detectors are scintillation spectrometers. In addition to a full bore gas holdup measurement, the spectral gas holdup tool also provides indications of the degree of flowstream lamination and the salinity of the liquid in the flowstream. An iterative data processing method optimizes the accuracy of the measured flowstream parameters.

Abstract: A powered headrest operating system includes a headrest connected to a seatback frame using rotational pins. An actuation mechanism rotatably connected to the seatback frame has a power actuated member connected to the headrest operating between retracted and extended positions to rotate the headrest from a fully retracted to a forward rotated position about an axis of rotation of the rotational pins. A release system rotatably connecting the headrest to the actuation mechanism retains the headrest at any forward rotated position while the actuation mechanism returns the power actuated member from the extended to the retracted positions if the headrest encounters an object blocking return to the retracted position. A biasing member connected to the seatback frame and the headrest creating a biasing force during headrest rotation away from the retracted position operates without actuation mechanism operating force to bias the headrest frame assembly toward the retracted position.

Title: Tubular cutting with debris filtration
Inventor: CROW STEPHEN L
IPC: E21B23/01
Filed: 2012-05-04
Abstract: A cut and pull spear is configured to obtain multiple grips in a tubular to be cut under tension. The slips are set mechanically with the aid of drag blocks to hold a portion of the assembly while a mandrel is manipulated. An annular seal is set in conjunction with the slips to provide well control during the cut. An internal bypass around the seal can be in the open position to allow circulation during the cut. The bypass can be closed to control a well kick with mechanical manipulation as the seal remains set. If the tubular will not release after an initial cut, the spear can be triggered to release and be reset at another location. The mandrel is open to circulation while the slips and seal are set and the cut is being made. Cuttings are filtered before entering the bypass to keep the cuttings out of the blowout preventers.
