摘要: The concentration of unspent zinc-based hydrogen sulfide scavenger in an oil-based drilling fluid is controlled by selectively dissolving and extracting the unspent scavenger in a solvent, such as glacial acetic acid, separating the aqueous solution, measuring the concentration of dissolved zinc in the aqueous solution, for example, with an X-ray fluorescence spectrograph, and utilizing the results of the measurements to proportion the extent of changes in concentration of the scavenger in the drilling fluid.

摘要: A method for quantifying the volume of oil in the fluids produced by solvent extracted sponge core distills only a portion of the solvent from the solvent/oil mixture, then determines and subtracts the remaining solvent volume to yield the actual volume of oil removed from the sponge.
