The Deepwater Horizon operation saw the injection of 771,272 gallons (2,919,582 litres) of dispersant at depth, in addition to the 1,072,514 gallons (4,059,907 litres) used on the surface.
With further water flooding, pollutions of water flooding well continuously push and cumulate in depth of the formation, which leads to the injection capability decreasing.
