This find will never compare to the incredible vast expanses of oil reserves in Iraq and Iran. The oil will go into US reserves so I don't see how
this can help with our demand on foreign oil.
This Gulf of Mexico find is estimated at between 3 and 15 billion barrels. The US currently uses about 20 million bbls a day, importing about 15
million bbls a day. This means at current consumption rates, 20 m/b/d, we would have a 750 days supply from this one find. Or, if we replaced all our
imports, we could have a 1,000 days of foreign oil independence. 2 years, 9 months. Saudi Arabian reserves are nearly 10 times those of the United
States.
“Reserve” in this instance means what the oil industry calls “proven reserves.” That is accomplished by drilling a number of exploratory wells
around the field, then estimating how much oil is under the ground and capable of being recovered. Of that kind of oil, the US has 29 billion barrels.
On that basis, and at current consumption rates, the US have enough oil to supply its needs for 11 years, provided imports of foreign oil continue at
the current level. Note: The US imports only about 2 m/b/d from the Persian Gulf. Most of our imported oil is from the Western Hemisphere.
This oil "reserve" is not to be confused with the nation's Strategic Petroleum Reserve which is about 750 million barrels of ready to go crude oil,
stored in old salt mines around the Louisiana-Texas Gulf Coast. 50 days supply at current consumption rates.
The find is in deep water and the wells are very deep. Chevron said the well set a variety of records, including the deepest well successfully tested
in the Gulf of Mexico. Chevron said the well was drilled more than 20,000 feet under the sea floor below 7,000 feet of water for a total depth of
28,175 feet. From the AP.
Post Script.
One major source of confusion when talking about oil “reserves” and “proven reserves” is this: assume an oil field. The field is defined by
the geological structure way below the ground. This is measured as if it was an earthquake. Seismically. Small explosions or air hammers pound the
earth and a number of seismic monitors sited around the field give readouts that when taken together, can be used to plot the geological structure,
the oil field. Suppose this underground structure is 20 X 20 miles, or 400 square miles. Based on other fields in similar geological structures, the
field can be estimated to hold, say 10 to 25 billion barrels of oil.
Suppose you drill a half dozen wells over an area of 4 miles X 5 miles. 20 square miles. You may discover this area holds 5 billion barrels of oil,
now called “proven” reserves. As that part of the field is used up, other exploratory wells will be drilled to add to the proven reserves. So, it
is entirely probable this one oil field will have approximately the same amount of “proven reserves” for many years, even though the field is
under active production. Many people mix the terms, “reserves” and “proven reserves.” The former is a guesstimate but the latter is very
reliable. DW
