A wellbore fluid recovery system and method is disclosed for recovering a
column of wellbore fluid within a stand of pipe when breaking out joints
of a wellbore tubular string. The system comprises a container that can be
mounted to seal around the joint. The container is preferably connected
through a first valve to a receiving tank to which a vacuum may be
applied. A vacuum tank may preferably be provided to assist in producing
the vacuum in the receiving tank and a second valve preferably connects
between the receiving tank and the vacuum tank. A third valve may be
provided for controlling flow from the receiving tank to a storage tank
for wellbore fluid. Prior to breaking the joint, a vacuum is preferably
applied to the receiving tank. The first valve may then be opened to
remove the fluid from the joint that is captured by the container in
response to the vacuum in the receiving tank. Subsequently, the third
valve is opened to permit drainage between the receiving tank and the
storage tank. The first and third valves may then be closed and the second
valve may be opened for producing a vacuum in the receiving tank. A vacuum
source may be used to increase the vacuum in the receiving tank further as
necessary. The second valve may then be closed and the system is ready to
operate as described above to receive fluid from the next joint.
