Briggs color cube

1. n. [Reservoir Characterization]
A system for color-coding three-dimensional information. This system is used in wireline log analysis to provide color shading in which the final color is determined by the values of three curves. One curve dictates the intensity of red, a second the intensity of green, and the third the intensity of blue. The final resulting color is the result of the three input curves. The input curves may be raw curves from the field or computed curves. When used for correlation work on cross sections, the curves must have been normalized to remove the effects of incorrect calibrations and borehole problems.
