get an indication if there is oil in the opening between the well casing and the pipe itself. based on that information, we can make a determination on these burst plates, which are placed periodically up and down the casing are still intact or if they burst and that gives us an idea of the pressure exerted. it will be a combination of the pressure in the well integrity tests and what we encounter when we drill into the well from below. >> christen hayes with reuters. you said that six-hour threshold. when you reach that six hours, if pressure is still low is that when you decide to ramp up the helix and the q-4000 and start collecting againy you said that the floating ricer is under construction and will be ready july 19th. >> we think we will be ready for proukd on the 19th.
