How does drilling....
Posted on 5/9/10 at 10:16 am

a relief well stop the existing 5000 (so they say) leak from the spud? I think BP has no clue as to what to do about the leak. Their primary concern is to capture the oil from the well. OT PE's please explain.

What is the spud?
The end of the riser?

I am not familiar with the Oil and gas industry but from my reading on this spill, from what I understand is that the Relief well will intersect with the original well shaft and use mud/concrete to seal off the original well. It will also serve to provide a way to relieve the pressure on the original well and allow for the well to be controlled.

Exact spot the drill bit enters the ground.

Actually, from a landman perspective, the spud refers to the date that drilling begins.... the original hole, so to speak. My concern is that an alternate well may not stop the "flow" from the original well bore.

Thanks for a clear, concise answer to my question.

from what I understand the relief well will drill in from the side and intersect at quite a depth. I don't know the depth but it is not at the surface and it is not the same place as the original well.

the relief well will intersect the original wellbore at or near the reservoir. it will allow you to establish circulation at the bottom of the hole.
the formation that is flowing has a specific bottom hole pressure. the well flows when the fluids in the hole exert a pressure against the formation that is less than reservoir pressure -- i.e. if the reservoir pressure is 10,000 psi and the fluid column in the hole exerts 9,900 psi on it, then the well will flow (these are just general numbers to illustrate the point).
normally, when you drill into a formation and take a kick, you can circulate in heavier weight fluid in order to regain control of the well by raising your bottom hole pressure. in this case, that is impossible without the relief well.
when the relief well enters the existing well, they will pump (as fast as possible) a heavy weight fluid that will control the formation (exert more pressure on bottom than the formation is capable of putting out). that will be followed by huge volumes of cement in order to permanently isolate the formation.

Thanks
so your prognosis for this "situation" is good?
Posted on 5/9/10 at 10:44 am to oilfieldtiger
^^^^ That is correct, the need to drill into the existing well, pump a high weight fluid that creates a higher hydrostatic pressure than the formation flowing and kill the well.
Spud refers to when they first start to drill into the sea floor or ground.

To my knowledge the oil isnt leaking from the spud hole.
that is why I was asking you what you meant by the spud.
To my knowledge it isnt leaking around the surface casing either.
Thus the relief well should work.

the relief well will definitely kill it, it's just very time consuming to execute, especially as you approach the original hole at final depth -- you need to keep stopping and employ very high tech surveying techniques to confirm your position relative to the original hole.
remember, you're trying to hit an 8.5" hole exactly on the nose from 18,000' away.

This is all good news to me. Thanks for the info

With the technology that Schlumberger and others in the industry have, it can be done in a timely manner. But as you state, more time than a normal drill well. In the last 5 years or so, the applications have been amazing.

You're right they got to be on of the top 5 biggest oil companies in the world because they don't know how to fix a leak.

Welllllllllll, they haven't have they?
So 2-3 months is the solution?
