<p>A downhole arrangement for oil wells and the like, wherein the fluid flow path to the bottom of the well is extended below the productive horizon, and forced circulation is thereby produced to take advantage of the effects of gravity on the fluid pressure, while phase segregation problems are reduced or eliminated. As a result, substantially enhanced downhole sampling quality is achieved, and said arrangement constitutes an approach that is compatible with any kind of fluid deposit, particularly saturated condensate gases.</p> |
