Abstract: Systems and methods for determining vector-ratio safety factors for wellbore tubular design are provided. Pressure and temperature data for at least one load point along a tubular component of a wellbore are obtained. An effective failure axial load expected at the load point is calculated during a downhole operation to be performed along one or more sections of the wellbore within a subsurface formation, based on the obtained data. An upper boundary and a lower boundary for the effective failure axial load are determined, based on physical properties of the tubular component at the load point. A midpoint of the effective failure axial load is calculated based on the upper and lower boundaries. A critical failure differential pressure is calculated, based on the midpoint of the effective failure axial load. A vector-ratio safety factor is calculated, based on the critical failure differential pressure relative to the effective failure axial load.

Abstract: Methods and systems are provided for generating a predictive tachometer profile at a tachometer of a vehicle. When an inertia phase of a transmission shift event is determined to be in progress, the predictive tachometer profile can be computed based on: a computed shift completion percentage; a difference between the current attained gear speed and the commanded gear speed; and a commanded engine torque that is determined based on the accelerator pedal position and the vehicle speed. The predictive tachometer profile can then be displayed at the tachometer. The predictive tachometer profile accounts for delays in a signal path between an engine speed sensor and the tachometer.
