  • Patent number: 12264574
    Abstract: A visual inspection system intended for inspection of the difficult to reach lateral wellhead ports and annulus is provided. The inspection of the annular ports is carried out prior to running a simplified annulus intervention system. The imaging assembly of the visual inspection system of the present invention can be manoeuvred to view and capture images of remote, inaccessible, difficult to reach locations in the lateral access port and the adjacent annular region, prior to running of annulus intervention system, thus enhancing the success rate of carrying out annulus interventions and increasing safety by increasing the efficiency of well intervention operations and reducing the risk of unintended incidents.

  • Patent number: 12246293
    Abstract: An elongate diffuser is disclosed comprising a diffuser body and a membrane attached to the diffuser body. The membrane is connected to the diffuser body so that introduction of gas at a working pressure into the diffuser displaces part of the membrane from contact with the diffuser body to provide an elongate sealed compartment between the membrane and a surface of the diffuser body. The compartment has a first lateral side interface region where the membrane contacts the diffuser body, a laterally intermediate region where the membrane is spaced apart from the diffuser body and a second lateral side interface region where the membrane contacts the diffuser body. The diffuser body surface which bounds the compartment comprises a recessed portion which is recessed away from the membrane between the first second lateral side interface regions.

  • Publication number: 20250067468
    Abstract: An electric process heater has a vessel containing a fluid and a plurality of elongated heating elements extending inside the vessel parallel to a central axis of the electric process heater. The plurality of elongated heating elements includes a first subset of elongated heating elements having a higher surface flux than a second subset of elongated heating elements. The electric process heater includes baffles to redirect a flow of the fluid over the elongated heating elements to improve heat transfer. The flow includes a parallel flow zone of parallel flow where the fluid flows parallel to the elongated heating elements and a crossflow zone of perpendicular flow where the fluid flows perpendicularly to the elongated heating elements. The first subset of elongated heating elements having the higher surface flux is disposed in the crossflow zone and the second subset of elongated heating elements is disposed in the parallel flow zone.

  • Publication number: 20250043992
    Abstract: Disclosed herein is an electric process heater having a vessel containing a fluid, a plurality of elongated heating elements extending inside the vessel parallel to a central axis of the electric process heater, wherein the heating elements comprise fins. Baffles are disposed at axial intervals inside the electric process heater to redirect the flow of fluid over the heating elements to provide improved heat transfer between the heating elements and the fluid inside the vessel. The baffles include flow-through heating element support holes for receiving and supporting the elongated heating elements. Each of the plurality of flow-through heating element support holes has a plurality of element-contacting tabs that protrude radially inwardly to support the heating elements within the baffles. The tabs define a plurality of gaps through which the fluid flows between the baffles and the heating elements to reduce a thermal differential at a heating element-baffle interface.

  • Publication number: 20240419981
    Abstract: In general, embodiments of the present invention provide systems, methods and computer readable media for automated dynamic data quality assessment. One aspect of the subject matter described in this specification includes the actions of receiving a data quality job including a new data sample; and, if the new data sample is determined to be added to a reservoir of data samples, sending a quality verification request to an oracle; receiving a new data sample quality estimate from the oracle; and adding the new data sample and estimate to the reservoir. A second aspect of the subject matter includes the actions of receiving, from a predictive model, a judgment associated with a new data sample; analyzing the new data sample based in part on the judgment to determine whether to send a new data sample quality verification request to an oracle; and, if a new data sample quality estimate is received from the oracle, determining whether to add the new data sample and the judgment to the reservoir.

  • Patent number: 12066804
    Abstract: A method may include receiving, via a first computing node of a cluster of computing nodes in a container orchestration system, a pod from a second computing node in the cluster of computing nodes. The method may also involve retrieving an image file that includes containers from a registry, such that the pod detail an indication of a location of the image file in the registry. The method then involves generating a package based on the one or more containers and one or more mapped commands implementable by a control system in an operational technology (OT) domain. The mapped commands correspond to operations performable by the control system that corresponds to commands specified in the containers. The method may then involve storing the package in a filesystem shared with the control system.
