Abstract: The quality factor of a NMR-antenna depends upon mud conductivity, formation resistivity and the borehole size. The Q of the antenna is measured. From measurement of one of formation conductivity or borehole size, the other can be determined.

Abstract: Wire line depths are estimated using cable depth measurements and accelerometer depth measurements made over a time interval encompassing the time for which the wire line depth is being estimated (105). A least squares smoothing filter or a weighted least squares smoothing filter may be used. Problems caused by washouts in the borehole are also addressed (113).

Abstract: An apparatus and method for estimating a parameter of interest using values of a beam property from two or more electromagnetic beams that both pass through at least part of an optical displacement device. The apparatus may include a Fabry-Perot interferometer, a collimated light source, and a detection array. At least one mirror of the interferometer may be operably coupled to an element receiving an external stimulus, such as pressure, force, and/or acceleration. The method includes using the apparatus.

Abstract: A method for estimating a property of subsurface material includes extracting a sample of the material using a downhole formation tester and performing a plurality of nuclear magnetic resonance (NMR) measurements on a sensitive volume in the sample where each measurement in the plurality is performed in a static homogeneous magnetic field with a pulsed magnetic field gradient that is different in magnitude from other NMR measurements to provide a waveform signal. The method further includes transforming each received waveform signal from a time domain into a frequency domain and comparing the frequency domain signal to a reference to provide proton chemical-shift information related to a chemical property of one or more molecules in the sample and transforming the frequency domain signals into a complex number domain that quantifies waveform signal amplitude changes to provide one or more diffusion rates with each diffusion rate being associated with a corresponding frequency.

Abstract: An apparatus and method for estimating a parameter of interest using a force responsive element comprising, at least in part, a balanced material. The balanced material is temperature insensitive over a specified range of temperatures such that the force responsive element may estimate the parameter of interest by responding to a desired force with relatively little interference due to temperature changes within the specified range of temperatures.

Abstract: A method and apparatus for estimating a flow rate of a phase of a multiphase fluid is disclosed. In the first method, nuclei in the fluid are polarized over two distances and a measured magnetization gives the relative fraction of two components of the fluid for a selected velocity. In the second method, nuclei in the fluid are polarized over a specified distance and measurements of the decay of spin echo signals is used to give the relative fraction of two components of the fluid for the selected velocity.

Abstract: A method and apparatus for estimating a flow rate of a phase of a multiphase fluid is disclosed. A first velocity distribution is obtained for a first set of nuclei in the fluid from a Nuclear Magnetic Resonance (NMR) signal received for the fluid in response to a first NMR excitation signal. A second velocity distribution is obtained for a second set of nuclei in the fluid from an NMR signal received for the fluid in response to a second NMR excitation signal. A velocity of the phase is estimated from the first velocity distribution and the second velocity distribution. The flow rate of the phase is estimated using the estimated velocity of the phase and an estimated volume fraction of the phase.

Abstract: The present disclosure relates to methods and apparatuses for calibrating a sensor, particularly a gravimeter, which involves positioning the sensor in at least three different orientations and calibrating the sensor using a linear model and the sensor outputs from the at least three different orientations. The method may include applying an external force to the sensor. The apparatus includes a processor and storage subsystem with a program that, when executed, implements the method.
