[QUOTE=pumpjack hand;37204]Do you know what the various DWH driller’s displays looked like exactly, was it a graph exactly like the chart we’re looking at, or digital LED, or dials? Recently calibrated? Cross checked with the mud logger’s readings? Do we know for a fact that it was working correctly at the time? There’s been mention of some things not working in various reports and presentations. The reason I’m wondering is because in other areas you are saying we need to wait for the investigation to unfurl, but here you assume you know enough to make a determination. I think it’s great to hammer in the points for basic well control, but there were a lot of things going wrong at the same time out there, so are you 100% sure of your assumption?[/QUOTE]
I wasn’t there. You asked if the driller could see the display as we all see the printed version. On 100% of rigs I’ve worked on the display is visible right in front of the driller. Additionally, the rig have an independent system with the data displayed in a similiar way. Hopefully, all are calibrated. A very big question mark would be associated with any volume control which isn’t in working order. Shut down and fix it.
