Abstract
The present invention relates generally to a method and system for geophysical exploration and more particularly to a method and system for obtaining selected physical properties of the subterranean formations surrounding a wellbore so as to aid the geophysicist in evaluating the oil and gas bearing potential of such formations. In one embodiment of the invention, core samples are obtained along the length of a wellbore and labeled with a machine readable bar code. A plurality of separately arranged measurement stations, each having a unique machine readable bar code, are provided for measuring properties of each sample. By use of a bar code a reader interconnected to a CPU, measurement of physical properties of the samples can be initiated at each measurement station. A log of each physical property as a function of depth can then be prepared with which explorationists can evaluate geophysical survey data for oil and gas potential.
