  • Formation evaluation neutron porosity

    In the field of formation evaluation, porosity is one of the key measurements to quantify oil and gas reserves. Neutron porosity measurement employs a neutron source to measure the hydrogen index in a reservoir, which is directly related to porosity. The Hydrogen Index (HI) of a material is defined as the ratio of the concentration of hydrogen atoms per cm3 in the material, to that of pure water at 75 °F. As hydrogen atoms are present in both water and oil filled reservoirs, measurement of the amount allows estimation of the amount of liquid-filled porosity.

  • Porosity sealing

    Porosity sealing is done through the process of vacuum impregnation. Vacuum impregnation seals porosity and leak paths that form during the casting or molding process. Vacuum impregnation stops casting porosity and allows manufacturers to use parts that would otherwise be scrapped. Vacuum impregnation is governed by Military Standard MIL-STD-276A as well as numerous proprietary and customer specifications.

  • Hydrogen gas porosity

    Hydrogen gas porosity is an aluminium casting defect in the form of a porosity or void in an aluminium casting caused by a high level of hydrogen gas (H2) dissolved in the aluminium at liquid phase. The solubility of hydrogen in solid aluminium is much smaller than in liquid aluminium. As the aluminium freezes, some of the hydrogen comes out of solution and forms bubbles, creating porosity in the solid aluminium.

  • Gas porosity

    Gas porosity is the fraction of a rock or sediment filled with a gas.

  • Sliced Porosity Block - CapitaLand Raffles City Chengdu

    Sliced Porosity Block - CapitaLand Raffles City Chengdu is a building complex built in Chengdu, China designed by Steven Holl Architects. It was built from 2008 to 2012. It celebrated its topping out in October 2011 at 123 meters.

  • Porosity Storage Reservoir

    Porosity Storage Reservoirs are man-made water storage reservoirs located in shallow alluvial (sand and gravel) deposits. The porosity, or void space, refers to the open spaces between the sand and gravel, and it is in this area that the water is stored. By separating and isolating a portion of an alluvial deposits through the use of walls made of natural materials, large reservoirs of water (up to a 100,000 acre feet) can be built up to 150 feet below ground. Securely storing water underground in this way protects the water from evaporative loss, unwanted contamination and is seen as low impact to the environment, compared to traditional dams and above ground water reservoirs.
