Abstract

Gas-phase partitioning tracer tests were conducted to measure water content for several porous media with different mean particle diameters and particle-size distributions. Methane was used as the nonreactive tracer and difluoromethane was used as the water-partitioning tracer. Water contents determined from the tracer-test results were similar to values measured gravimetrically. These results support the utility of the gas-phase tracer method for measuring water content in a variety of porous media.
