Abstract
A single stage high pressure mercury injection capillary pressure measurement apparatus includes a sample sub-assembly, a transducer sub-assembly, a hydraulic intensifier, and a gas cylinder. The sample sub-assembly includes a casing having walls defining an interior volume, a penetrometer arranged in the casing, the penetrometer having walls defining a sample volume, an annular space defined between the walls of the casing and the walls of the penetrometer, and a common chamber fluidly connected to the annular space by a fluid line and to the sample volume of the penetrometer by a tubing. The transducer sub-assembly is fluidly connected to the sample sub-assembly via the common chamber and includes a plurality of high-pressure transducers a plurality of low-pressure transducers. The hydraulic intensifier is fluidly connected to the common chamber and is configured to apply a high pressure to the annular space.
