The relief well isn’t for testing. It is for delivering heavy mud to first balance the pressure and stop the flow, then delivery of the cement to permanently stop the flow. >>>>>>>>>>>
Sure and it is testing too...for well casing integrity. It has been running close to the gusher well for a few weeks. 20 ft is what I read a few weeks ago
They are at the near bottom of the well. Testing the casing integrity at this point has little meaning.
Do you have any details on how they can do that?
All I have heard about is the ranging device to sense the magnetic field of the WW casing.
