This summers energy bill, signed into law on Aug. 8, included a somewhat
controversial provision to inventory the oil and natural gas in the outer continental
shelf (OCS) of the United States. While most of the OCS is currently off-limits
to exploration and production, advocates of the inventory have said that it
is logical to know what resources are out there. Some opponents worry, however,
that any accurate inventory would include new drilling. Now, with hurricanes
Katrina and Rita hitting the nations energy systems particularly hard,
Congress is considering new ways to produce oil and gas, including possibly
finding ways around the OCS moratoria.
States have jurisdiction over mineral (primarily oil and gas) exploration and
development from their coasts to about 5 kilometers offshore, where the U.S.
Minerals Management Service (MMS) takes over. The OCS then encompasses about
1.76 billion acres of territory from 5 to 320 kilometers offshore, about 10
percent of which is currently available for leasing. Congressional and presidential
moratoria in place since the 1990s prohibit exploration and development activities
off the entire East and West coasts, parts of Alaska and the eastern Gulf of
Mexico.
Still, MMS manages about 8,300 separate leases. Of those, more than 8,000 are
in the Gulf of Mexico, producing about 30 percent of the nations oil and
21 percent of its natural gas. By 2006, the Gulf could be producing 40 percent
of the nations oil, according to MMS. That is a lot of our eggs
in one single basket, says Walter Cruickshank, MMS deputy director.
Every five years, MMS develops a new plan for where to allow leases. So the
inventory, which Congress directed to be completed within six months, will be
included in the next five-year plan, about which MMS is soliciting public comment.
Current estimates suggest that the entire OCS contains 76 billion barrels of
technically recoverable oil and 406.1 trillion cubic feet of gas. But those
estimates, especially for the moratoria areas, are somewhat out of date, Cruickshank
says, which is part of the reason Congress directed the inventory.
The inventory may not help update energy estimates, however, as most of the
moratoria areas have not been assessed in nearly two decades or more, Cruickshank
says. An inventory is most effective with seismic testing or modeling, but no
such new activities will take place, he says, because Congress did not appropriate
any funding for new testing. And without the prospect of development, companies
are not likely to perform expensive new field studies on their own. So MMS will
have to rely on new ways to look at old information and on anyone
who has information on resources to share it, he says.
In the meantime, the offshore landscape could be further changing, with Congress
acting quickly to enact new legislation in the weeks following the hurricanes,
as gasoline prices soared, and citizens clamored for policy-makers to intervene.
On Sept. 28, the House Resources Committee, chaired by Richard Pombo (R-Calif.),
approved a new bill that would allow states to opt out of the coastal
leasing bans, and thus allow development 45 kilometers or more offshore. If
states petition the federal government to withdraw from the existing moratoria
and develop resources off their coasts, they would receive revenues from royalties,
a real incentive. Amid controversy on Sept. 30, a committee spokesperson announced
that the bill would not go to the House floor after all and instead may become
part of the budget reconciliation package.
The House is using Katrina to push through measures quickly that it has
tried to push through before, says a staffer for a Democratic representative
in the Resources committee, who wished to remain anonymous. But the legislation
may face an uphill battle in the Senate, especially because it also allows drilling
in the Arctic National Wildlife Refuge and cuts back on many environmental regulations.
The Senate is certain to take a more deliberative approach than the House,
which pretty much implemented the fast track to push this huge bill through,
says the staff member. Were in a tough time, paying the price of
not having a broader energy policy its now that the argument becomes
stronger for pursuing greater conservation and renewable energy measures,
rather than simply drilling more.
But with the Department of Energy projecting at least a 1.5-percent annual growth
in demand for oil and gas, and oil imports already at about 60 percent, Gale
Norton, secretary of the Interior, said in an Aug. 22 press release: We
would be irresponsible if we did not consider how we might develop [the] abundant
domestic resources in the OCS.

Oil is one of Venezuelas most precious commodities, and recently, President
Hugo Chávez has been sharing it with his Caribbean neighbors.
In June, 13 Caribbean countries signed deals with Venezuela to receive oil cheaply,
followed by deals with Argentina, Brazil, Uruguay and Paraguay. Cuba has been
getting most of its oil from Venezuela since April, in return for doctors and
teachers. And in August, when protesters in Ecuador dynamited oil pipelines
and vandalized pumping machinery, crippling oil exports, Chávez stepped
in and covered Ecuadors oil export commitments, free and clear.
Critics have charged that Chávez is buying friends and influence with
oil, with the purpose of undermining the United States and extending his own
power in the Western Hemisphere. There is no economic rationale in these
deals, said Ricardo Hausmann, an economist at Harvard and a former minister
of planning in Venezuela, in an article in The Christian Science Monitor
on Aug. 25. It is a political investment, perhaps for the day when
Chávez decides to radicalize his Bolivarian revolution, he said.
Other observers suggest that it is altruism, and that Chávez is simply
being a good neighbor. Regardless of Chávezs intentions, it could
mean trouble for the United States, industry pundits say. Chávez proclaimed
on Aug. 14 that the daily supply of 1.5 million barrels of oil to the United
States could be halted if U.S. aggressions against the Venezuelan
government continue, according to The Christian Science Monitor.
Deborah A. Kramer, the Magnesium Commodity Specialist for the U.S. Geological Survey, has compiled the following information about magnesium, an important mineral for aluminum production.
Magnesium, often confused with last months mineral of the month manganese,
is valued primarily because of its light weight and high strength-to-weight
ratio. Magnesium is the eighth most abundant element and constitutes about 2
percent of the Earths crust. It is the third most plentiful element dissolved
in seawater, with a concentration averaging 0.13 percent. Magnesium is found
in over 60 minerals, and also is recovered from seawater, wells, and lake brines
and bitterns.
Magnesium metal has been produced continuously in the United States since it
was first recovered in 1916. The height of magnesium production in the United
States was during World War II, when 15 magnesium plants were operating to supply
magnesium for aircraft production.
Today, magnesium is produced at only one plant in the United States. Its largest
use is as an alloying addition to increase the hardness and corrosion resistance
of aluminum. The single largest application for magnesium-containing alloys
of aluminum is the aluminum beverage can, which has a magnesium content of about
4.5 percent in the lid and about 1.1 percent in the can body. Without magnesium
in the alloys, aluminum beverage cans would be as flexible as a toothpaste tube.
Magnesium and its alloys have structural uses in the forms of die castings,
sand and permanent mold castings, and wrought products. Automakers have introduced
magnesium components such as clutch housings, instrument panel supports, headlamp
assemblies and grill covers to reduce vehicular weight. From the 1977 to the
2004 model years, magnesium die castings in automotive applications have increased
from an average of 1 pound per vehicle to 10 pounds per vehicle. The power tool
market includes magnesium castings in chain saws and lawnmower housings. Die-cast
magnesium also is used in video camera, cell phone and computer components.
In the iron and steel industry, magnesium is used as an external hot-metal desulfurization
agent, and it is used in the production of nodular iron. Magnesium is used as
a catalyst for producing certain organic chemicals and petrochemicals and as
a reducing agent for producing other nonferrous metals. Anodes of magnesium
are frequently used in underground pipes and water tanks, water heaters and
marine applications.
World production of primary magnesium metal in 2004 was about 584,000 metric
tons, with China as the worlds leading producer, accounting for about
426,000 metric tons. The sole magnesium plant in the United States has the capacity
to produce 43,000 metric tons per year, but U.S. consumption in 2004 was about
140,000 metric tons, much of which was supplied by imports. In 2004, Canada,
China, Israel and Russia supplied 92 percent of the 99,000 metric tons of U.S.
imports.
Magnesium recycled from old scrap supplied about 15 percent of U.S. consumption.
Magnesium is recycled from new scrap generated mainly during the production
of magnesium structural products. Recycled magnesium also comes from old scrap
such as used beverage cans and other discarded consumer products.
