Well inflow phenomena in chalk gas condensate reservoirs - Effect of fluid sampling

Fluid flow and thermodynamic processes in saturated gas condensate reservoirs is complicated because<br>the composition of the saturated gas flowing to the weIl in the reservoir is altered during the production.<br>The pressure draw down at the well will cause heavy components to drop out of solution. When producing<br>from low permeability reservoirs as the chalk reservoirs in the Danish sector of the North Sea,<br>thermodynamic processes at the weIl are especially pronounced, because of the large pressure draw down<br>required to maintain production.
