BP hopes to start permanently plugging the oil well in the Gulf Tuesday.
Engineers are running their final tests a mile underwater before attempting the so-called static kill.
If the tests look good, crews will spend Tuesday slowly pumping heavy mud into BP’s broken well.
The experiment may lead to plugging the well for good.
Engineers will decide whether they can follow the mud with cement, or whether they need to wait and use the relief wells to make a permanent seal.
The decision on whether or not to put cement in after the mud will be completely dependent on the assessment of the integrity of the well bore.

For Charter Boat Captain Ralph Smith, he's seen business fall off 70 to 80 percent this season. “I want to get back to normal if there is such a thing anymore.”
Gulf Coast leaders still have plenty of concerns about the millions of gallons of oil in the water.
Residents are also worried about the impact of chemicals BP used to keep oil from reaching the shore.
The EPA released a new study showing the dispersant is no more or less toxic to marine life than the oil alone.
EPA test results were released Monday, after the Obama administration was criticized for letting BP use excessive amounts of chemical dispersants before knowing how toxic they were.
