Gas recombination is not a "measurement" in the same sense as a CCE or CVD experiment: it is the sample-preparation and quality-control step that creates the live reservoir fluid on which every subsequent gas-condensate or wet-gas PVT study depends.

The Gas Flash test takes a sample of reservoir gas at reservoir pressure and temperature and subjects it to a single, abrupt pressure reduction to a defined flash pressure (separator or atmospheric).

The Gas Depletion test reproduces, at the cell scale, the non-equilibrium material-balance history that a dry or wet gas reservoir undergoes as it is produced down its decline curve.

The retrograde condensation (liquid dropout) test maps how much liquid phase forms inside a gas condensate as reservoir pressure declines below the dew point.

The dew point determination is the cornerstone constant-composition experiment for any gas condensate reservoir.

Fluid type: gas condensate (retrograde gas)

For gas condensate fluids the Constant Composition Expansion is commonly run under the names Constant Mass Expansion (CME), Constant Mass Depletion (CMD), Constant Mass Study, or Pressure-Volume (P-V) relation.

The multiple-contact miscibility test, also called the multiple-contact mixing or multcontact experiment, reproduces in the laboratory the repeated, stage-wise mass exchange that occurs when an injection gas (, , , lean or enriched hydrocarbon gas, or a flue-gas blend) advances…
