Abstract: A method of planning and/or performing an energy industry operation includes estimating variable coefficient of friction (CoF) functions defining the variation of a CoF as a function of a downhole condition dependent on a selected operational parameter of an energy industry operation, the operation including deploying a downhole component configured to perform the operation, each variable CoF function associated with a different value of the selected operational parameter.

Abstract: An embodiment of a method of performing an energy industry operation includes: deploying a carrier in an earth formation, the carrier including a downhole component configured to perform the operation; performing the operation according to operational parameters; measuring a condition, the condition including at least one of a surface condition and a downhole condition, and generating measurement data representing the measured condition; tuning a simulation model of the operation based on the measurement data, the model being a mathematical model configured to estimate the condition based on the selected operational parameters; selecting a hypothetical adjustment to one or more selected operational parameters; applying the hypothetical adjustment to the simulation model to generate predicted conditions of the operation; and based on the predicted conditions representing an improvement to the operation, adjusting operational parameters according to the hypothetical adjustment.
