    Supply is dictated by demand.

    The consumer is in no way the villian here.

    Re: ‘Fundamental Mistake’ Made Before BP Oil Spill, Lawmakers Say

    It sounds like you two are talking about two different things.

    ADK_Forever talking about cement plugs

    apdst talking about cementing the casing joints - between the casing and bedrock.

    But both of you are on the right track according to some experts belief of how the tragedy occurred..Some believe an O-ring and/or cementing wasn't done or was improperly done while installing plugs.

    Here's a link to an illustration with explanations of how and what may have occurred.

    More conservative absolutist thinking. Reducing demand and eliminating demand are not the same thing. And to consider us blameless is really burying your head in the sand.

    The only way to totally eliminate the chance of an oil well blow out, is to totally stop drilling. What are we to do if there is zero oil supply? Food for thought.

    The OP says they were drilling. The OP in another thead says they were cementing. My point is, that everything that's been posted, so far, is pure speculation, as to what happened.

    As to the link you posted. Is that possible? The riser is bolted to the well head. There would have to be a casing failure for gas to go up through the riser.

    And, besides that, the link you posted shows the riser inside the casing which isn't how the assembly is put together. The casing and drill pipe go inside the riser, not the other way around.

    I’m well aware that they cement between the pipe and the earth as I had provided you with this diagram:

    Note that this diagram doesn't show any cement.

    Care to tell us how a cased hole, with a flow shoe at the bottom, blows out and shoves 4 miles worth of cement to the drill floor? Do you know what any of that means?
    This sure sounds like you’re saying they cement the entire hole.

    Next explanation?

    You claimed in another thread that the cementing job is the reason that the well blew out. For that to be possible, the gas pressure would have to travel up, through the cement; the cement between the casing and the well bore. Please, explain how there was enough pressure to push four miles of cement up to the drill floor, in just a few seconds. There would have to be upwards of 200 thousand pounds of pressure to accomplish that.

    Care to explain to us how that is possible?

    I don't believe I ever blamed the cementing job for this. If you agree there were 3 plugs, and not the entire well cemented, why do you think the oil/gas would have had to blow thru 4 miles of cement?!?!?! The oil/gas would have had plenty enough pressure to blowout the plugs (probably demolishing them) up thru the well.

    How does a gas bubble shoot up through solid earth. Got any explanation for that one?

    What spurs my curiosity the most, is how many different stories we're going to hear about how this well blew out.

    What the hell are you talking about? The oil/gas blew up past the 3 cement plugs, which were separated by sea water instead of mud, inside the well. The cement was outside the well hole casing between the casing and the earth.

    Look at the diagrams!
