Abstract: A method can include constructing a numerical model of a material matrix, where the numerical model includes cells; performing a simulation of physical phenomena with respect to time using the numerical model; during the performing, analyzing one of the cells as to physical characteristics of the material matrix; and, responsive to the analyzing and during the performing, assigning one or more properties to the cell that indicate failure of the material matrix of the cell without removing the cell from the numerical model.

Abstract: A method can include receiving real-time, time series data from equipment at a wellsite that includes a wellbore in contact with a fluid reservoir; processing the time series data as input to a trained machine learning model to predict a future solids event related to influx of solids into the wellbore from the fluid reservoir; and outputting a time of the future solids event.
