On ABC’s “Good Morning America” on Friday, Admiral Allen said the top kill effort was continuing, and that BP engineers had been able “to push the hydrocarbons and the oil down with the mud.”
But the technician working on the effort said later Friday that despite the injections at various pressure levels, engineers had been able to keep less than 10 percent of the injection fluids inside the stack of pipes above the well. He said that was barely an improvement on Wednesday’s results when the operation began and was suspended after 11 hours. BP resumed the pumping effort Thursday evening for about 10 more hours.
“I won’t say progress was zero, but I don’t know if we can round up enough mud to make it work,” the technician said. “Everyone is disappointed at this time.”
So, just as we described in this post last evening, they’re losing too much mud being blown out of the BOP and out the riser pipe by the pressure from oil/gas gushing up the well. That means they can’t yet get enough mud down the column to overcome the massive pressure of gas/oil gushing up the well and force that column of fluids back down the well. And the "junk shot" has so far not clogged up the BOP enough to reduce the loss of mud out the BOP top.
