At any rate, you did ask about risks during the conduction of the test. Well the main risk was that the pressure buildup during the test. If that pressure reached 8,000-9,000 psi, it could have caused damage itself to a partially fractured well bore. Especially if it was kept up that high over time. Since we did not get that high, that risk did not occur. Now running at 6,700 psi has risks too, but they are less of a factor. Again, we do not want to damage the well bore. It makes killing the well permanently much more difficult. Absolute worse case would be a sea floor breach with little resistance to flow.
Thank you very much!
