ARROW-PLOT WITH COLOR CODED AZIMUTH

摘要

A method of visually presenting information representative of the dip characteristics of earth formations by means of a polychromatic chart. The preferred method comprises representing the dip information by means of an arrow plot comprising oriented symbols such as a nail so that the location of each nail head and the orientation of its tips are respectively representative of the amplitude of the dip and the azimuth direction of the dip. Each nail head is colored as a function of the direction of the dip with the color selected from a palette comprising a plurality of colors corresponding to dip azimuth directions.
