  • Patent number: 11566518
    Abstract: A method may include obtaining various well logs or various core samples regarding a geological region of interest. The method may further include determining various permeability values, various porosity values, and various dolomite volume fraction values regarding the geological region of interest using the well logs or the core samples. The dolomite volume fraction values may correspond to a percentage of dolomite in a total mineral volume. The method may further include determining, using the porosity values, various permeability thresholds corresponding to various predetermined reservoir qualities. The method may further include generating, using the permeability thresholds, the permeability values, and the dolomite volume fraction values, a reservoir model including various dolomite boundaries defining the predetermined reservoir qualities. The method may further include determining a hydrocarbon trap prediction using the reservoir model.

  • Publication number: 20220393333
    Abstract: The present disclosure relates to an antenna mounting device for antenna assembly, where the antenna assembly comprises a base station antenna that extends longitudinally and a remote radio unit. The antenna mounting device comprises a first mounting unit, a second mounting unit and an optional third mounting unit. The first mounting unit is configured to pivotally connect a remote radio unit to a foundational component and provide the antenna assembly with a pivot point relative to the foundational component. The second mounting unit is configured to connect the base station antenna to a foundational component in the longitudinal extension direction of the base station antenna, below the first mounting unit and at a distance from the first mounting unit. The second mounting unit has an adjustable effective connection length between the base station antenna and foundational component, where the effective connection length determines the mechanical tilt angle of the antenna assembly.

  • Patent number: 11366163
    Abstract: The present invention relates to a solid testing platform and method for function testing of an intelligent phase-change switch. The testing platform includes a primary controller, a first module, a second module, a capacitor C, an intelligent phase-change switch, and a transformer. The primary controller is respectively connected to the first module and the second module, and is configured to control the operation of the first module and the second module. The first module and the second module are connected in parallel to the capacitor C. the first module is configured to feed back excess energy of the capacitor C to a distribution network. The second module is configured to control magnitude and direction of a current that flows through the intelligent phase-change switch. The capacitor C is configured to perform energy support, filtering, and smoothing.

  • Patent number: 7605279
    Abstract: Provided is a production process by which a novel alicyclic oxetane compound which has an oxetane ring, has excellent light transmission in the near ultraviolet region, and is useful as a cationically polymerizable monomer can be easily obtained. The production process which is for obtaining an alicyclic oxetane compound includes subjecting an aromatic oxetane compound to nuclear hydrogenation in high-pressure hydrogen in the presence of a hydrogenation catalyst. For example, when 4,4?-bis[(3-ethyloxetan-3-yl)methoxymethyl]biphenyl is used as the aromatic oxetane compound, 4,4?-bis[(3-ethyloxetan-3-yl)methoxymethyl]bicyclohexyl is obtained as the alicyclic oxetane compound.
