The first relief well, which started drilling May 2, has reached a measured depth of 16,546 feet and has successfully completed a second ”ranging” run using specialist equipment inserted into the well to help more precisely locate the MC252 well. Drilling and ranging operations will continue over the next few weeks as the well progresses towards the target intercept depth of approximately 18,000 feet. Once intercept has occurred, operations are expected to begin to kill the flow of oil and gas from the reservoir by pumping specialised heavy fluids down the relief well.The second relief well, which started May 16, is at a measured depth of 12,038 feet. Both wells are still estimated to take approximately three months to complete from commencement of drilling.

What about the suction? I hear these are not that big. The suction from the up pour might suck the drill up and cause more problems.
However, what does a relief well do other than spread the problem? I mean, we ARE working off an old broken pipe. Is patching a part of it a guarantee it will not break again?

I appreciate your optimism but I would not say they are "nearing completion" just because BP's graphic shows them getting close to the most difficult part of the endeavor.
Not nit picking but at the end of the day the only information we have as regards this comes from BP. I have the three graphics issued and each shows a further advance. Under the assumption that these are correct then the first well is close.
to the OP who is hardly some BP apologist
.... I am hopeful about the relief wells but also feel they should be filled and capped and the area left the hell alone if they succeed.
Whatever the outcome I have the strong feeling this will not be over even once the well is hopefully sealed up or relief wells in place.

Let's hope this works as planned.
However, since this oil resovoir is under enough pressure to already have caused one blowout, why is BP confident that it won't happend again?
Even if they do succeed in getting it plugged, wouldn't the pressure buildup underneath the plug eventually cause it to fail too?
As much as I hate to think BP would profit from this disaster, wouldn't using the two relief wells to obtain oil twice as fast be a better option? It seems to me that would ensure the pressure in the existing well is minimized enough that they can begin to pump in a couple miles of concrete into the original well, ensuring that the plug doesn't fail.
In my mind, if the ocean floor and a mile of water above it, is not enough to quell the oil and methane flow, how does one expect a measly few feet/yards of cement to plug it up?
What I don't like if the final point in this article:
* If the Macondo well is too damaged to revisit, it is possible the company could turn one of the relief wells into a producing well.
This is confusing. How could they have been that close so long ago?
