Abstract
A system and method for capturing fluid samples from a borehole is described. The system includes an outer pipe (703) and an inner pipe (702) disposed within the outer pipe. A removable capture assembly may be disposed within the inner pipe proximate to a top of the inner pipe. A flow port (706) may provide fluid communication with the inner pipe. The system may also include a flow mandrel (756) disposed around the outer pipe. The flow mandrel may include a flow path in fluid communication with an annular space within the outer pipe, and the removable capture assembly may be at least partially disposed within the flow mandrel.
Claims20
An fluid sample capture tool, comprising:
- an outer pipe;
- an inner pipe disposed within the outer pipe;
- a removable capture assembly disposed within the inner pipe proximate to a top of the inner pipe;
- a flow port providing fluid communication with the inner pipe;
- and
- a flow mandrel disposed around the outer pipe, wherein the flow mandrel includes a flow path in fluid communication with an annular space within the outer pipe, wherein the removable capture assembly is at least partially disposed within the flow mandrel.
A method for capturing fluid sample at the surface of a drilling system, comprising:
- deploying a fluid container from a fluid sampling tool disposed in a borehole, wherein the fluid sampling tool is coupled to a first drilling pipe;
- capturing the fluid container at a removable capture assembly within a fluid sample capture tool coupled to the first drilling pipe at the surface;
- and
- retrieving the fluid container from the fluid sample capture tool.
A fluid sample capture tool, comprising:
- an outer pipe, wherein the outer pipe is sized to couple with a first drilling pipe and a top drive mechanism;
- an inner pipe disposed within the outer pipe, wherein the inner pipe is sized to couple with a second drilling pipe, wherein the second drilling pipe is disposed within the first drilling pipe;
- a side flow port providing fluid communication with the inner pipe;
- a flow mandrel disposed around the outer pipe, wherein the flow mandrel includes a flow path in fluid communication with an annular space within the outer pipe;
- and
- an overshot latch disposed within the inner pipe, wherein the overshot latch engages with a fluid container received through the inner pipe;
- and
- a sealing cap coupled to the overshot latch and threadedly engaged with a top opening on the inner pipe
