Number: 73/152.18
Name: Measuring and testing > Borehole or drilling (e.g., drill loading factor, drilling rate, rate of fluid flow) > Fluid flow measuring or fluid analysis
Description: Subject matter wherein the determination of the physical characteristic of the borehole, the casing, or the drill rigging is made by either (a) detecting the movement of or the presence of a fluid which has traveled either (1) from the formation into the borehole, (2) from the borehole into the formation, (3) from the outside of the borehole into the borehole, or (d) from inside the borehole to the outside of the borehole; (b) measuring a rate, a direction, or a magnitude of fluid flow either (1) from the formation into the borehole, (2) from the borehole into the formation, (3) from the outside of the borehole into the borehole, or (4) from inside the borehole to the outside of the borehole, or (c) detecting or measuring the presence of or an amount of a constituent of a fluid within the borehole, the ratio of one constituent of the fluid to another constituent of the fluid or the effect of a constituent of the fluid.
