Abstract
The invention provides a method for determining the organic matter content of sedimentary rocks from data recorded in the well by at least two well-logging probes measuring different parameters. Two probes are chosen, one for responding in the same direction ot a variation of the water and organic matter content of the rocks, the other for responding very differently to a variation of one or other of these same components, and both so that the iso-organic matter content lines in a three pole diagram are substantially merged whether the third pole is the water pole or the clay pole. The position of the line I(0%) is determined experimentally and the organic matter content is derived therefrom corresponding to each pair of values of the parameters measured in the well. In a diagram where the parameters used depend, for example, on the transit time of sound in the rock and on the electric resistivity of the formations, the iso-content lines form a family of parallel lines.
