  • Patent number: 10732315
    Abstract: Methods and apparatus for evaluating a volume of an earth formation carried out using complex dielectric measurements. Methods include making measurements of complex permittivity at a plurality of frequencies; identifying an optimal frequency by: identifying candidate frequencies having a corresponding measurement with a respective sensitivity to at least one of i) salinity and ii) water-filled porosity, by determining that each respective sensitivity is substantially independent of rock texture; selecting a maximum of the candidate frequencies as the optimal frequency; using a table search method based on a forward model to generate an initial estimate of at least two parameters of the volume; and using the initial estimate as an initial condition for an inversion of other measurements at frequencies other than the optimal frequency to generate a final solution comprising final estimates for formation properties. The at least two parameters may comprise water salinity and water filled porosity.

  • Patent number: 10698127
    Abstract: An antenna shield latches around a mandrel or wellbore tubular to protect an antenna carried by the mandrel. The antenna shield opens to facilitate installation over the mandrel, and closes the around the antenna to provide robust protection from the downhole environment. Radial sections of the antenna shield are coupled to one another such that the antenna shield maintains a one piece construction, and the sections may pivot to move the antenna shield between open and closed configurations. Readily opening and closing the antenna shield facilitates maintenance and repair of the antenna and reusability of the antenna shield.

  • Patent number: 10684346
    Abstract: The disclosed method corrects consumption measurements provided by meters presumed to be connected to a same network. The measurements taken by the meters at time intervals are collected in a form of samples used to determine electrical quantities in relation with currents and voltages relating to the meters. A selection of a group of retained samples among the samples considered to be valid, corresponding to a load range or a range of load variation ratio carried by the network based on the electrical quantities is performed. Correction functions of the consumption measurements are defined from the group of retained samples, and the consumption measurements are adapted according to the correction functions. An anomaly corresponding to an electrical non-compliance of a meter can be detected by the method.
