  • Patent number: 12291963
    Abstract: Methods and systems are provided characterizing a formation traversed by a wellbore, wherein the formation includes at least a flushed zone and an uninvaded zone, which involve obtaining well log data based on plurality of different well log measurements of the formation at multiple depths in the wellbore. The well log data is used by a computational model that solves for a set of petrophysical parameters that characterize a portion of the formation corresponding to the multiple depths in the wellbore, wherein the set of petrophysical parameters include a cementation exponent, a saturation exponent, and a flushed zone water resistivity. The solved-for set of petrophysical parameters can be used to determine a value of water saturation of the uninvaded zone for the portion of the formation corresponding to the multiple depths in the wellbore.

  • Publication number: 20250142425
    Abstract: Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A terminal device receives, from a first network device, a conditional reconfiguration indicating that a subsequent conditional cell change is enabled. If the subsequent conditional cell change to a candidate cell is to be performed after a cell change or addition is performed, the terminal device determines a first counter value, the first counter value being different from a second counter value used for the cell change or addition, and determines, based on the first counter value, a security key for communication with a second network device providing the candidate cell. In this way, a security key is determined for a subsequent conditional cell change.

  • Publication number: 20250110250
    Abstract: Aspects described herein provide for methods and apparatus for interpretation of borehole sonic dispersion data using data-driven machine learning based approaches. Training datasets are generated from two possible sources. First, application of machine learning enabled automatic dipole interpretation (MLADI) and/or machine learning enabled automatic quadrupole interpretation (MLAQI) methods on field data processing will naturally create substantial volume of labeled data, i.e., pairing dispersion data with dispersion modes labeled by MLADI and MLAQI. Second, it is also possible to generate large volume of synthetic dispersion data from known model parameters. These two types of labeled data can be used either separately or in combination to train neural network models. These models can map dispersion data to modal dispersion much more efficiently.
