petroleum engineering Petroleum engineering is a field of engineering concerned with the activities related to the production of hydrocarbons, which can be either crude oil or natural gas or both. Exploration and production are deemed to fall within the ''upstrea ...

gas Gas is a state of matter that has neither a fixed volume nor a fixed shape and is a compressible fluid. A ''pure gas'' is made up of individual atoms (e.g. a noble gas like neon) or molecules of either a single type of atom ( elements such as ...

porous Porosity or void fraction is a measure of the void (i.e. "empty") spaces in a material, and is a fraction of the volume of voids over the total volume, between 0 and 1, or as a percentage between 0% and 100%. Strictly speaking, some tests measure ...

rocks. Minipermeametry has been used in the oil industry since the late 1960s (Eijpe and Weber, 1971) without becoming in any way a standard experimental method in core analysis or reservoir characterisation. The laboratory minipermeametry can make important contributions both as an improved methodology within experimental petrophysics and as a source of data invaluable in routine reservoir characterisation (C. HALVORSEN AND A. HURST, 1990) The values obtained from the minipermeameter should possibly be calibrated by a Klinkenberg correction
