Abstract: A method of manufacturing a roller cone includes machining a cone blank and thereby defining one or more land surfaces and one or more insert grooves on the cone blank, surface hardening the cone blank, and milling a plurality of recesses into at least one of the one or more land surfaces. The method further includes subjecting the cone blank to a quenching process, forming an insert hole at each recess, and inserting an insert into each insert hole.

Abstract: Methods and systems for well tool wear classification system are provided. A wear classifier tool is configured to classify wear of a scanned well tool using a machine learning engine. Computer-readable memory stores a training dataset and a trained ML model. The training data set includes scanned image data and associated labels representative of classification types of failure. The trained ML model has a neural network. The wear classifier tool can output data identifying a failure mode of the scanned well tool based on classification of input by the machine learning engine. A database is configured to stored historical data on scanner type, patterns of scanner cutting elements, sensor type, and age and usage conditions. A scanning system includes a camera and a three-dimensional (3D) scanner configured to scan a drill bit.

Abstract: A drill bit includes a bit body providing one or more blades and defining a cone section extending from a centerline of the bit body a first distance, a nose section extending from the cone section a second distance, a shoulder section extending from the nose section a third distance, and a gauge section extending from the shoulder section a fourth distance. The drill but further includes one or more cutting elements mounted to the one or more blades outside of the cone section such that the cone section is void of cutting elements, and a plurality of milling elements secured to the bit body within the cone section.

Abstract: A method of quantifying wear data on a well tool includes scanning a used well tool with a scanner and thereby generating a scanned file of the used well tool, the scanner being in communication with a computer system, aligning the scanned file with an original solid model file of the used well tool and thereby obtaining and displaying an overlay output, wherein the solid model file is stored on the computer system and identifies individual wear parts of the used well tool, creating and placing a digital feature on one or more of the individual wear parts displayed on the overlay output, and calculating deviation between the solid model file and the scanned file at each digital feature of the one or more individual wear parts and thereby determining material removed from the individual wear parts of the used well tool.

Abstract: A method of quantifying wear data on a well tool includes identifying the well tool based on a solid model file and a data file corresponding to the well tool, wherein the solid model and data files are stored on a computer system and separately identify wear parts of the well tool, scanning the well tool with a scanner and thereby generating a scanned file of the well tool, the scanner being in communication with the computer system, aligning the scanned file with the solid model file to obtain an overlay output, creating digital features on the wear parts of the scanned file, and calculating deviation between the solid model file and the scanned file at the digital features for the wear parts and thereby determining material removed from the wear parts of the well tool.

Abstract: This application describes a system and techniques for managing the replication, migration, or backing up of virtual machines (VM) operating on a computing device. The techniques include managing real time or near real replication or migration of VM operations logs between computing devices. The operations logs include information or data that would enable another VM to function or operate in the same manner as the VM that generated the operations logs. Techniques are presented herein to insure the replication or migration process of VMs is not open ended or indefinite. For example, the write rate of the source operations log is managed to insure the replication or migration of the source operations log to destination device terminates within a reasonable amount of time.

Abstract: Techniques are disclosed for the non-disruptive and reliable live migration of a virtual machine (VM) from a source host to a target host, where network data is placed directly into the VM's memory. When a live migration begins, a network interface card (NIC) of the source stops placing newly received packets into the VM's memory. A virtual server driver (VSP) on the source stores the packets being processed and forces a return of the memory where the packets are stored to the NIC. When the VM has been migrated to the target, and the source VSP has transferred the stored packets to the target host, the VM resumes processing the packets, and when the VM sends messages to the target NIC that the memory associated with a processed packet is free, a VSP on the target intercepts that message, blocking the target NIC from receiving it.
