| Description |
This project was an
add-on to the current LSU Well Control Project (No.8). It's purpose was to develop
specifications and designs for improved Drill String Safety Valves (DSSV). Safety valves
and inside blowout preventers were found to be one of the categories experiencing the
highest failure rates during routine testing and well-control events. |
| Progress |
The Department of
Mechanical Engineering had two groups of undergraduate students design, build, and test
DSSV. Their work was presented in two papers given at the LSU/MMS Well Control Workshop,
November 19-20, 1996, in Baton Rouge, Louisiana (papers were published in the
proceedings). The first paper focused on testing the of two DSSV's. The valves were tested
under static pressure conditions and closing on flow. The results were a function of valve
design, condition, and the closing technique of the operator. A third paper was presented
at the April 1, 1998, LSU Well Control Workshop. The final paper concluded that the key to
better performance of DSSV is the ability to overcome the high torque of actuation. |
