Abstract
A computer-based method is provided for modeling and visualizing a property of a subterranean earth formation while drilling a borehole therethrough. The computer-based method gathers electromagnetic signals corresponding to a current measurement station location of a measurement-while-drilling tool, and generates a multilayer model corresponding to such electromagnetic signals. A histogram characterizing uncertainty of the multilayer model is used to generate a set of color hue values which represent predictions of the formation property for depth values above/below the tool, and a corresponding set of saturation values (which represent uncertainties for these predictions). A curtain plot is generated and displayed. The curtain plot employs colors to visualize formation property predictions for depth values above/below the tool over successive measurement station locations. A new column of the curtain plot is generated for the current measurement station location. The color values of the new column are based upon the set of color hue values and the set of saturation values derived from the histogram. The saturation levels of the new column represent uncertainties for the correspon…
