It's a significant risk to controlling the well. There is a suggestion from the evidence that flow could be taking place up the production casing annulus (I think this is the case) - but with so many liner strings, there could be a loss of integrity anywhere. It's unlikely that the flow could find its way all the way up the outside of the various casing strings. But this well has had mud losses just before penetrating the reservoir, and this zone of weakness would probably be the first to take new losses. All of these speak to the importance of killing from the bottom up, via the relief wells. Any mud that begins to work its way upward from the source of flow is also exerting its hydrostatic pressure downward, back to the reservoir. The higher the column, the less the well is inclined to flow. This will have a great effect on any potential weak zones that may have been taking a portion of the well's flow. It is also the best way to prevent making things worse. The top kill, on the other hand, was one of the best ways to make things worse - it's good that they stopped it so soon after commencing. I've worked in areas that are plagued with long term underground blowouts, some of them still going after a dozen years. It's not a legacy I would want my name attached to. I flew over the GOM a few days ago on my way to HouTex. No difficulty spotting the oil. There were long lines of it stretching into the distance every so often, and the occasional floating puddle. Lots of support craft out there, mopping up. A very sad sight to see. Regards to all Aggie
