we're hooufing forward now it looks like. >> but still, they haven't been so clear about a time line, but they're telling us about how they're going to test it in intervals. we could know between six and 48 hours. walk us through that process. they're going to be quite careful in how they do this. they know what's on the line and they do not want to mess this up. >> right. i mean, it's a 8-hour test. they're going to stop and take measurements and analyze the data that they get every six hours . so if things go completely haywire out of the gate, they could shut this down after six hours if they need to. but those pressure readings is what they'll be looking at closely to make sure they're not doing any more damage to that well bore that goes into the earth surface and deep, almost three miles deep into the earth. so that's what they're concerned about. that's what they'll be monitoring closely. >> we've been hearing so much about integrity tests and pressure. but once again, explain low pressure, bad. high pressure, good.
