Abstract
Method of taking a sample from a flow of fluid passing out of a well communicating with a permeable subsurface formation, which fluid comprises gaseous and liquid components, the method including the steps of allowing the fluid to flow from the well at a predetermined pressure, mixing the components of the fluid flowing at this pressure, draining a sample stream of the mixed components at this pressure, and storing the components at a pressure that is approximately equal to this pressure.

6. Apparatus for taking a sample from a flow of fluid passing out of a well communicating with a permeable underground formation, comprising:
-
a conduit system with an inlet and an outlet, said inlet being suitable for being brought into communication with the interior of said well, said conduit system comprising; a first pipe and a second pipe arranged in a generally parallel configuration whereby parallel flow of fluid may take place through said first and second pipe; valve means cooperating with each pipe, said valve means being arranged to close off said respective pipe at will; fluid mixing means arranged in the interior of said second pipe and having a body with a central axis, said body having a plurality of passages extending therethrough between the upstream side of said body to the downstream side thereof, each passage having a central axis, the axes of all passages passing through a common point on the central axis of said body adjacent the downstream side of said body; and
,a fluid sampling conduit communicating at its entry thereto with the interior of said second pipe in the proximity of said fluid mixing means. - View Dependent Claims (11, 13, 14, 16, 17, 18, 19)

12. Method of taking a sample from a flow of fluid passing out of a well communicating with a permeable subsurface formation, which fluid comprises gaseous and liquid components, comprising the steps of:
-
passing said fluid through a first pipe from said well at a predetermined pressure; passing said fluid through a second pipe in substantially parallel flow with said first pipe, said fluid being at said predetermined pressure; mixing the components of said fluid being passed through said second pipe; draining a sample stream of said mixed components at said predetermined pressure; and
,storing said components at a pressure that is approximately equal to said predetermined pressure.
