n: the standard unit of measurement for neutron logs. Standardisation of this unit results from the calibration of each logging tool model in the API neutron test pit at the University of Houston.

n: a French unit of measurement, equal to 191.833 feet (58.5 metres).

n: a counterprinter with selective means for setting price per standard unit of measurement. It can compute the total price for a quantity of product delivered.

n: a unit of measurement of the American Petroleum Institute that indicates the weight, or density, of oil. See API gravity.

n: a number that does not have a unit of measurement associated with it.

n: an internationally used unit of measurement equal to 2.47 acres.

abbr: million cubic feet;a common unit of measurement for large quantities of gas.

million standard feet of gas.

n: (Pa) the SI metric unit of measurement for pressure and stress and a component in the measurement of viscosity. A pascal is equal to a force of 1 newton acting on an area of 1 square metre.

a unit of pressure equal to 1/100,000 of a bar.

n: 1. a measure of the ease with which a fluid flows through the connecting pore spaces of rock or cement. The unit of measurement is the rnilIidarcy. 2. fluid conductivity of a porous medium. 3. ability of a fluid to flow within the interconnected pore network of a porous medium. See absolute permeability, effective permeability, relative permeability.

n: the units of permeability are darcies or millidarcies.

n: the viscosity of a liquid in which a force of 1 dyne (a unit of measurement of small amounts of force) exerted tangentially on a surface of 1 square centimebe of either of two parallel planes 1 centimetre apart will move one plane at the rate of 1 centimetre per second in reference to the other plane, with the space between the two planes filled with the liquid.
