gas permeability of rocks
1Permeability (earth sciences) — Permeability in the earth sciences (commonly symbolized as κ , or k ) is a measure of the ability of a material (typically, a rock or unconsolidated material) to transmit fluids. It is of great importance in determining the flow characteristics… …
2Permeability — Permeability, permeable and semipermeable have several meanings:*Permeability (electromagnetism), the degree of magnetization of a material in response to a magnetic field *Permeability (earth sciences), a measure of the ability of a material… …
3permeability — /perr mee euh bil i tee/, n. 1. the property or state of being permeable. 2. Also called magnetic permeability. Elect. a measure of the change in magnetic induction produced when a magnetic material replaces air, expressed as a coefficient or a… …
4natural gas — a combustible mixture of gaseous hydrocarbons that accumulates in porous sedimentary rocks, esp. those yielding petroleum, consisting usually of over 80 percent methane together with minor amounts of ethane, propane, butane, nitrogen, and,… …
5Shale gas — may also refer to gas generated from oil shaleShale gas is natural gas produced from shale. Because shales ordinarily have insufficient permeability to allow significant fluid flow to a well bore, most shales are not sources of natural gas. Shale …
6Газопроницаемость — свойства вещества и в т. ч. горных пород пропускать газ благодаря наличию в них сообщающихся между собой пор или трещин. В свободных от воды порах и трещинах распространение газа происходит под влиянием разности давлений (эффузия) и Г. выражается …
7газопроникність гірських порід — газопроницаемость горных пород gas permeability of rocks, rocks permeability to gas *Gasdurchlässigkeit der Gesteine спроможність гірських порід при деякому перепаді тиску пропускати через себе газ. Розрізнюють абсолютну, фазову і відносну Г.г.п …
