Interesting Math …
When engineers report quantities of a gas like methane they are generally referring to Standard Temperature and Pressure (STP), which is room temperature and 1 atmospheric pressure. Engineers can convert the STP gas value to another gas value at a different temperature and pressure. The mass of the gas (of course) stays constant but the volume the gas occupies changes with temperature and pressure.
“A BP spokesman said the company was burning about 30 million cubic feet of natural gas daily from the source of the leak … “
Gulf Oil Full Of Methane
30 million cubic feet methane = 224,415,584 gallons = 5,343,228 barrels at STP
The static pressure of seawater at 5000 feet deep is about 150 atmospheres.
5,343,228 barrels at STP / 150 = 35,621 barrels methane gas at the sea floor.
(The change in volume due to temperature is ignored, as I don’t know the temperature.)
Therefore BP admits AT LEAST 35,600 barrels of methane gas is pouring out of the BOP at the sea floor. This is just the amount they are burning at the surface (30 million cubic feet). This DOES NOT include the methane that is venting to the ocean NOR any of the liquid oil that is captured (15,000 barrels per day) NOR the liquid oil that is venting to the ocean.
So now BP admits that they are capturing 35,600 barrels (gas) and 15,000 barrels (oil) = 50,600 barrels gas/oil as it exits the BOP on the seafloor.
Clearly the total VOLUME of the gas and liquid pouring out of the BOP is in excess of 50,000 barrels and probably way more than 100,000 barrels per day. Just the gas they admit they are burning at the surface equals 35,600 barrels per day at the hydrostatic pressure at the BOP 5,000 feet below the ocean surface.
That’s one HELL of a WELL!
And that’s a sh*tload of gas at the BOP.
