摘要： The disclosure relates to an apparatus and method for determining the permeability and the porosity of small sections at and just below the surface of a slabbed sample of porous rock or other material. The measurement is performed by forcing air or other gas through a central passageway of a deformable (e.g. rubber) probe tip pressed against the surface of the sample to be tested. Permeability of the matter directly under the probe tip is computed from the ratio of flow rate into the sample to the pressure drop between the gas in the probe-tip and the ambient atmosphere. A preferred and an alternative means for measuring flow rate are disclosed involving the use of an optical interferometer to detect displacement of a bellows chamber. The apparatus of the invention includes a fact-acting valve such that immediately after calculation of the permeability of the sample under defined conditions, a precise value of the porosity of the same sample may be computed from the transient pressure change that is observed after cutting off air flow into the sample from the probe.

摘要： An apparatus and method for measuring the filtration efficiency of a moving air-permeable web. The apparatus includes a sampling head with an upstream head and a downstream head disposed on opposite sides of the moving web and spaced apart to define a path for web travel. Particle laden air from the upstream head passes through the moving web and is collected in the downstream head where a sampling probe is disposed to collect filtered air for efficiency measurements. The method can be practice on-line in the media manufacturing process to continuously monitor the filtration characteristics and if necessary change the process condition to maintain the filtration characteristics within design parameters.

摘要： An apparatus for determining the effect of dilution and/or diffusion of the gaseous components of a gas flow passing through a gas permeable test object is claimed. The apparatus comprises a source of calibrating gas, a laminar resistance coupled to the source of calibrating gas with the gas flowing through the laminar resistance, and a volumeter is coupled to the laminar resistance for measuring the volume of gas flowing therethrough. The gas from the laminar resistance flows through the test object to a gas concentration measuring device for receiving and for measuring the concentration thereof. A bypass device is provided for bypassing the flow of gas around the test object, and a suction device draws gas from the source to the measuring device.

摘要： The apparatus disclosed herein is useful for testing unconsolidated sand samples from oil-bearing or gas-bearing earth formations. Basically, the device comprises a cylinder equipped with opposing pistons. The sand sample is placed in the cylinder between the pistons and then compacted by moving the pistons toward each other. The force for moving the pistons is supplied by a fluid, such as air or hydraulic oil, which is injected under pressure into a chamber defined in the cylinder behind each piston. The compacted sample is then subjected to various test procedures involving permeability measurements, consolidation tests, and flow studies.

摘要： The systems and method described in this specification relate to at least partially restoring porosity and brine permeability of carbonate core samples. The systems and methods include extracting a carbonate core sample from a subterranean formation. The extracted carbonate core sample is inserted into a core flooding test machine. A first porosity and a first brine permeability of the extracted carbonate core sample is measured. A fluid is pumped through the extracted carbonate core sample to flood the carbonate core sample. The fluid includes at least one of a high-molecular weight polymer solution and a gel particle solution. The systems and methods include at least partially restoring the porosity and the brine permeability of the carbonate core sample by pumping an oxidizing solution through the flooded carbonate core sample and heating the carbonate core sample to a temperature of at least 60° C. after pumping the oxidizing solution through the carbonate core sample.
