Systems and methods provide a bottom hole assembly for a wellbore that includes a drill bit and multiple drilling tools. The multiple drilling tools include multiple sensors configured to capture a multiple instances of a common measurement type at multiple locations along a drill string. The multiple drilling tools also include processing circuitry configured to compare the multiple instances of the common measurement type to determine a difference among the multiple instances. The processing circuitry is also configured to determine that the difference is greater than a threshold corresponding to an inference of high frequency torsional oscillation. Furthermore, the processing circuitry is further configured to send an indication of an occurrence of high frequency torsional oscillation in the bottom hole assembly.

A multi-disciplinary optimization (MDO) framework and workflow facilitates analysis and optimization of set of designs of a pressure-controlling component. The MDO workflow generally enables design workflow integration and automation, which can improve engineering efficiency, and enables automated optimization within the workflow automation, which facilitates performance and reliability improvement for product development. The MDO workflow enables the integration of computer-aided design (CAD), finite element analysis (FEA), digital manufacturing simulation (DMS), and optimization packages to facilitate testing and optimization of a set of pressure-controlling component designs. As such, the MDO framework and workflow improve the efficiency of the design process by providing a scalable solution for automating aspects of the design process for a set of designs of a pressure-controlling component, which may represent a product family or a set of competing alternative designs.

An asset management system that includes a field asset management system; a maintenance management system; and a digital avatar associated with a specific asset. The digital avatar has an automatic Model that is customized for the associated asset. The digital avatar automatically receives information from at least one of the field asset management system or maintenance management system as information associated with the asset is entered into the at least one of the field asset management system or maintenance management system. The automatic Model automatically runs with the new information and provides a new operating parameter for use by at least the field asset management system.

A pump rod can include a body that includes a longitudinal axis; and a pin at an end of the body where the pin includes threads where the threads include tangential elliptical roots.

Pump rod connection

A thread structure in accordance to one or more embodiments includes a thread extending helically along a portion of a bit body in spaced thread turns, the thread having a crest extending between a first flank and a second flank and a root extending between the thread turns, the root having a curvature defined by a portion of an ellipse tangentially adjoining the first and second flank at respective flank transition points, the ellipse having a major axis extending parallel to the axis and a minor axis extending perpendicular to the major axis and through a root bottom.

A method of cold rolling a thread on a tubular support member of a rotary shouldered thread connection includes obtaining an original root depth of a thread root, cold rolling the thread until a minimum increased root depth tolerance is achieved. The thread may be cold rolled with a wheel tip having an elliptical profile.

A thread structure in accordance to one or more embodiments includes a thread extending helically along the cylindrical member in spaced thread turns, the thread having a crest extending between a first flank and a second flank and a root extending between the thread turns, the root having a curvature defined by a portion of an ellipse tangentially adjoining the first and second flank at respective flank transition points, the ellipse having a major axis extending parallel to the axis and a minor axis extending perpendicular to the major axis and through a root bottom.
