  • 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.

  • Patent number: 12289862
    Abstract: A single-phase immersion cooling system includes an immersion cooling tank having a component area, which is separate from a main chamber and is configured to receive a heat-generating electronic device. A coolant circulates along a flow path, in a chamber path through the main chamber and a component path through the component area. A rotating propeller is mounted within the immersion cooling tank, causing a driven flow path in the component area. The driven flow path is configured to cause contact between the coolant in the driven flow path and the heat-generating electronic device when the heat-generating electronic device is received within the component area. The coolant in the driven flow path circulates at a faster speed than the coolant in the chamber path.
