The test went very well with no failures with the exception of the gas detectors which did not register to the sample bottle and the nitrogen back-up was at 1750 psi. In summary: The AUDI rig and surrounding location was in a wery clean state and the crew went through the test quickly. ,~ There was extr~itrogen on the rig and the electrician has more sensors for. the gas detectors and should have them fixed in a few"days.
