Abstract: The preparation of a concrete having an air bubble system consisting of finely divided air bubbles is often desirable for the purpose of protecting the concrete against damages, for instance caused by frost. The composition of the air bubble system in fresh, or green concrete is identical to the composition in the hardened concrete and the invention is directed to a method of determining the quality of the air bubble system in fresh concrete, expressed by means of the specific surface of the system. The method consists in that the air bubbles are expelled from a sample of the fresh concrete, for instance by agitation in glycerol by means of a magnetic agitator and that the expelled air bubbles while ascending in for instance water, which is superposed upon the glycerol layer, are registered as a function of time whereupon the quality of the air bubble system is expressed by means of the analysis result.

Abstract: ABSTRACT      A method is disclosed for using a pair of tracers to determine the in-situ residual oil saturation surrounding a single wellbore in subterranean reservoirs.  The first tracer has a labile hydrogen atom, and the second tracer is formed by substitution of a hydrogen isotope, i.e., tritium or deuterium, for this labile hydrogen atom.  The mixture comprising the tracer and its isotopic form is injected into the reservoir where the isotope exchanges with non-isotopic hydrogen from the reservoir water.  The produced sample is analyzed for the presence of both tracers, and the residual oil saturation is calculated.
