Class Information
Number: 73/152.41
Name: Measuring and testing > Borehole or drilling (e.g., drill loading factor, drilling rate, rate of fluid flow) > Fluid flow measuring or fluid analysis > Fluid injection into formation > Determining permeability or saturation
Description: Subject matter wherein the determination of the characteristic of the borehole, the casing, or the drill rigging is made by measuring either (a) a quality of either a bulk formation of a borehole or of selected constituents of a formation of a borehole to be penetrated by a liquid or a gas passing through pores or openings therein or (b) the maximum impregnation by gas, water, or oil of a bulk formation of a borehole or of selected constituents of a formation.
