Coke and Chemistry, 2011
The gas-tightness of coke-oven doors may be improved by means of a flexible membrane seal in which the edge of the membrane is pressed against the perimeter by a spring; gas-exhaust channels; and separation of the door’s welded housing from the lining module using a sealing frame.

Introduction to Tight Gas Reservoirs
2013Tight gas reservoirs represent a significant portion of natural gas reservoirs worldwide. Tight gas sand is generally characterized as a formation with effective permeability less than 0.1 md (Law and Curtis 2002).

Flow Units: From Conventional to Tight-Gas to Shale-Gas to Tight-Oil to Shale-Oil Reservoirs
SPE Reservoir Evaluation & Engineering, 2013Summary Core data from various North American basins with the support of limited amounts of data from other basins around the world have shown in the past that process speed or delivery speed (the ratio of permeability to porosity) provides a continuum between conventional, tight-, and shale-gas reservoirs (Aguilera 2010a).
