a multiple completion in which the upper zone flows to the surface through the annulus formed by the casing and the deeper zone tubing. Usually used only in sweet, dry gas upper completions.

n: 1. gas whose water content has been reduced by a dehydration process. 2.gas containing few or no hydrocarbons commercially recoverable as liquid product. Also called lean gas.

a gas stream without condensate. Note: even dry gas at bottom hole conditions may have up to two barrels of water vapor per million standard cubic ft of gas. Dry gas on the process side has all liquids removed.

Dry Gas is a natural gas containing insufficient quantities of hydrocarbons heavier than methane to allow their commercial extraction or to require their removal in order to render the gas suitable for fuel use. (Also called Lean Gas) (SPE).

n: a well that produces natural gas. gas show n: the gas that appears in drilling fluid returns, indicating the presence of a gas zone.

n: natrul gas well with commercial value .the gas produced by this well
is usually dry gas or the gas contained little condensate oil.

the fraction of the pore space occupied by water when the hydrocarbon content is at maximum. This level of water can only be reduced below this level by flow of very dry gas that evaporates the water. Rewetting of a core with saturation below the irreduci

n: 1. residue gas remaining after recovery of natural gas liquids in a gasprocessing plant. 2. unprocessed gas containing few or no recoverable natural gas liquids. Also called dry gas.

a near dry gas, containing only a trace of condensate.

condensate that precipitates in the pore space of the rock in a previously dry gas (single phase) reservoir as the pressure drops below the dew point. The building condensate severely reduces the permeability to gas.

a measurement of the processing of kerogen towards dry methane gas. Usually expressed at Vitronite reflection percent. Vro <0.6 is a immature oil, 0.6 to 1.0 is a oil with dissolved gas, 1.0 to 1.3 is wet gas and >1.4 is dry gas. Vro over values of about
