Halliburton said that the report "accurately places responsibility on BP as the well owner for its operational decisions, " which included using a heavyfluid designed to keep gas from entering the well, called drilling mud, that was "too light" and probably mixed with the cement at the bottom of the well, and drilling too narrow a well.
The effort, called a "top kill, " involved plugging the ruptured deep-sea well by pumping heavy drilling fluid into it from the surface, nearly a mile above.
Both countries play versions of the 4-2-3-1 formation that dominates the game at the highest level and both use fluid movement, technically skilled players and heavy pressing to lean on opponents all over the field.
