  • Patent number: 10698836
    Abstract: Disclosed herein is a virtual cache and method in a processor for supporting multiple threads on the same cache line. The processor is configured to support virtual memory and multiple threads. The virtual cache directory includes a plurality of directory entries, each entry is associated with a cache line. Each cache line has a corresponding tag. The tag includes a logical address, an address space identifier, a real address bit indicator, and a per thread validity bit for each thread that accesses the cache line. When a subsequent thread determines that the cache line is valid for that thread the validity bit for that thread is set, while not invalidating any validity bits for other threads.

  • Patent number: 10697256
    Abstract: An electronic control system comprises a first tubular handling tool, a sensor, and a controller. The controller is configured to control actuation of the first tubular handling tool in response to an electronic signal received from the sensor that corresponds to an operational characteristic of the first tubular handling tool. The electronic control system functions as an electronic interlock system to prevent mishandling of a tubular. A method of controlling a tubular handling tool comprises measuring an operational characteristic of the tubular handling tool, communicating the operational characteristic to a controller in the form of an electronic signal, and using the controller to control actuation of the tubular handling tool in response to the measured operational characteristic.

  • Publication number: 20200199952
    Abstract: Embodiments of the present disclosure relate to apparatus and methods for making up and evaluating tubular threaded connections. A tong assembly may be used for making up threaded connections. A threaded connection may be made up automatically by controlling the rotation speed of the tong assembly according to measurements of torque, turns, and/or time. After a threaded connection is made up, measurements of time, torque, and/or turns may be corrected based on operating parameters. The corrected measurements may be evaluated for indications of failure, such as discontinuity, torque spikes, and torque drops. The threaded connection is then accepted or rejected based on the evaluation.

  • Patent number: 10606762
    Abstract: Disclosed herein is a virtual cache directory in a processor that eliminates address translations when the virtual address and the real address in the cache directory are the same. The processor is configured to support virtual memory and multiple threads. The virtual cache directory includes a plurality of directory entries, each entry is associated with a cache line. Each cache line has a tag. The tag includes a logical address, an address space identifier, a real address bit indicator, and virtual address to real address indicator. This virtual address to real address indicator indicates if the logical address and the real address are the same. When activated, address translation is not performed.

  • Publication number: 20200063506
    Abstract: A method of connecting or disconnecting a first tubular to a second tubular includes engaging the first tubular with a power tong; engaging the second tubular with a backup tong; and rotating the first tubular relative to the second tubular. The method also includes, while rotating, monitoring a distance between the backup tong and the power tong and comparing the distance to a first threshold value; and stopping rotation of the first tubular when the distance equals to the first threshold value. According to one embodiment, a tong assembly includes a power tong, a backup tong, a sensor configured to measure a distance between the power tong and the backup tong, and a controller configured to compare the distance to a threshold value.

  • Patent number: 10465494
    Abstract: A system for controlling a set of tools for hydrocarbon recovery includes a remote controller and a device controller. The remote controller is communicatively coupled to the device controller. The device controller is generally configured to receive a command to operate one of the plurality of tools from the remote controller. Based on the command, the device controller generates one or more instructions executable by a controller associated with the one of the plurality of tools. The device controller transmits the one or more instructions to the one of the plurality of tools.
