n: the expansion of a gas, vapour, or liquid stream from a higher pressure to a lower pressure with no change in enthalpy of the stream.

abbr: articulated loading platform.

radioactive decay process where the loss of an alpha particle from the nucleus lowers the atomic number by two and the atomic mass by four.

n: one of the extremely small particles of an atom that is ejected from a radioactive substance (such as radium or uranium) as it disintegrates. Alpha particles have a positive charge.

the initial wave of gravel transport when packing a well with a deviation over 55o.

n: (ALP) offshore platform in which the riser is jointed to allow for changes in water level, current, and so on.

the returning wave of gravel after the alpha wave when packing a well over about 55o deviation.

n: a specialpurpose valve used to facilitate spacing out and flanging up the well, run in on the tubing string.

n: the heat content of fuel. A thermodynamic property, it is the sum of the internal energy of a body and the product of its pressure multiplied by its volume.

n: a type of rock consisting of thinly bedded sandstone and shale, thought to be the result of the action of turbidity currents;a succession of turbidites originating in marine depositional basins, usually near the base of the continental slope. Flysch deposites are especially common in the Alpine region of Europe.
