    Abstract: A subterranean screen assembly comprises a base pipe with end connections to attach to a pipe string and a portion that is perforated or slotted; and a coated screen radially outwardly disposed of the base pipe. The coated screen comprises a screen substrate and a coating disposed on a surface of the screen substrate; the coating comprising an amorphous diamond like carbon doped with about 10 to about 30 atomic percent of silicon, about 10 to about 20 atomic percent of oxygen, or a combination comprising at least one of the foregoing dopants, or a polymer comprising a fluoropolymer, a silicone, or a combination comprising at least one of the foregoing.

    Abstract: A coating having a gradient composite structure, applied to a substrate, which may be a disposable tool. The gradient composite comprises a bonding component and an erosion and/or corrosion resistant component. When applied to a disposable tool, such as a ball and seat assembly in a downhole environment, the coating enhances the performance of disintegrable materials used in such tools. The coating may be configured to expire at the end of a selected duration, allowing the underlying material to disintegrate.

    Abstract: A switching network includes an upper tier including a master switch and a lower tier including a plurality of lower tier entities. The master switch includes a plurality of ports each coupled to a respective one of the plurality of lower tier entities. Each port includes a plurality of virtual ports each corresponding to a respective one of a plurality of remote physical interfaces (RPIs) at the lower tier entity coupled to that port. Each port also includes a receive interface that, responsive to data traffic from a particular lower tier entity, queues the data traffic to the virtual port that corresponds to the RPI on the particular lower tier entity that was the source of the data traffic. The master switch further includes a switch controller that switches data traffic from the virtual port to an egress port from which the data traffic is forwarded.

    Abstract: A switching network includes first, second and third switches coupled for communication, such that the first and third switches communicate data traffic via the second switch. The first switch is operable to request transmission credits from the third switch, receive the transmission credits from the third switch and perform transmission of data traffic in reference to the transmission credits. The third switch is operable to receive the request for transmission credits from the first switch, generate the transmission credits and transmit the transmission credits to the first switch via the second switch. The second switch is operable to modify the transmission credits transmitted by the third switch prior to receipt of the transmission credits at the first switch.
