OFF-SHORE DRILLING | Much
of the world runs on oil, most from land, but some from ocean drilling.
To support our modern lifestyle, from cars to plastics, the world has
used more than one trillion barrels of oil to date. Another trillion is
underground, waiting to be tapped. But given the locations of the
remaining oil, the cost is likely to be far higher.
Canada's tar sands are becoming a serious issue, and with the Arctic
ice melting, oil companies are racing to drill there with serious
environmental issues involved. |

| The case against oil drilling off-shore |
A steady stream of
pollution from offshore rigs causes a wide range of health and
reproductive
problems for fish and other marine life. Offshore drilling
exposes
wildlife to the threat of oil spills that would devastate their
populations. Offshore drilling activities
destroy kelp beds, reefs and coastal wetlands.
OVER
ITS LIFETIME A SINGLE OIL RIG CAN . . .
- Dump more than 90,000
metric tons of drilling fluid and metal cuttings into the ocean.
- Drill between 50-100 wells, each
dumping 25,000 pounds of toxic metals, such as lead, chromium and
mercury, and
potent carcinogens like toluene, benzene, and xylene into the ocean.
- Pollute the air
as much as 7,000 cars driving 50
miles a day.

| Some of the dangers with drilling |
July 2011: Is oil
drilling inherently flawed? Documents released under freedom of information legislation, reveal there
are oil and gas spills in North Sea every week. Jake
Molloy, general secretary of the Offshore Industry Liaison Committee (OILC), a union representing North Sea workers, said
Deepwater Horizon showed that "even the most up-to-date, cutting-edge
safety technology can go wrong if it is not maintained properly and not
operated by competent people". He added: "We have been very lucky in
the UK that we have not had another major incident with multiple fatalities. We
have come very close on several occasions, very, very close. It is more luck
than good management in some cases. Some operators don't give a damn. Because
of the high price of oil, they are cutting corners. Some of them are overdue
for prosecution." (More than 100 potentially lethal oil and gas spills took place on rigs in the North Sea in 2009 and 2010) link
Risk-taking rises as oil rigs in the Gulf drill deeper. link The Montara spill November 2009: Timor Sea oil rig blaze caused serious ecosystem damage.
For ten weeks
since August 21 2009, engineers struggled to stop a well-head
accident which resulted an uncontrolled discharge of oil and gas at an estimated 400 barrels (17,000 gallons)
a day being released into waters north of Australia causing an
ecological disaster to marine life. Estimates from satellite imagery
indicate that the slick spread over 50,000 square kilometers of
ocean. The cost of cleanup has been estimated at over $4.8 billion. link Piers
Verstegen, from the Conservation Council of Western Australia, says the
spill is an ecological disaster. "Humpback whales, an endangered species, go to that area and that region to
calf and give birth and this oil spill is happening just off the Kimberley
coast." Conservationists believe that, in its rush to exploit abundant natural
resources, Australia risks inflicting irreparable damage on its fragile environment. link October 25 2009 - photo gallery of marine damage link | Deepwater Horizon spill / Gulf news |
Gulf of Mexico news: Since 2001 there have been 69
offshore deaths, 1,349 injuries and 858 fires and explosions in the Gulf,
according to the federal Minerals Management Service. - link More on the BP Deepwater Horizon disaster below. [Roughly 70% of offshore oil and
gas leases in the Gulf of Mexico and more than half of onshore leases on
federal lands remain idle, neither producing nor under active exploration and
development by companies who hold those leases. link]
The BP Deepwater Horizon spill - largest marine oil disaster ever.  Scientists have
affirmed the Macondo BP oil disaster as the largest marine oil accident ever. After the April 20 2010 explosion,
officials claimed that the flow could not be measured. Then estimates began starting
at 1,000 barrels a day; then 5,000; then 12,000 to 19,000; then upward from
there. Using a new technique to analyze underwater video of the well riser,
they say it leaked some 56,000 to 68,000 barrels daily, maybe more, until the
first effective cap was installed, on July 15. Their estimate of the total oil
escaped into the open ocean is some 4.4 million barrels, close to the most
recent consensus of government advisors. link Guardian timeline of events
Gulf of Mexico has a long history of spills. Federal
records show that between 1964 and 2009, prior to the BP spill, 517,847
barrels of petroleum had been dumped into the Gulf, twice the amount of
the Exxon Valdez spill. While spills have been decreasing, the history
of spills in the Gulf have largely been unreported, and frequently
understated by the companies themselves. link [According to NOAA,
there are 3,858 oil and gas platforms operating in the Gulf of Mexico.] Sept. 15 2010:
The U.S. Interior Department requires oil and gas companies to plug
nearly 3,500 non-producing wells in the Gulf permanently and dismantle
650 platforms no longer being used. link April 2011: 3,200 wells in Gulf still unplugged. The Associated Press reports that in addition to 27,000
oil and gas wells that were sealed with cement and abandoned without any
regular monitoring in the Gulf of Mexico, another 3,200 old wells have quietly
been left unused without any cement plugging to help prevent leaks. Without
those plugs, there is little to prevent powerful leaks from pushing to the
surface. link July 2010: Now is the time to count the ecological cost with
the spill seemingly under control. In the 85 days of the leak, nearly
184 million gallons of crude oil gushed into the Gulf of Mexico, equal
to the amount of oil Americans burn every 5 hours 10 minutes. The
damage yet to be revealed will be far worse, however, than a few dead
birds and tar balls along 500 miles of coast. link Research shows up
to 40% of gulf oil spill was potent methane gas. link _________________________________________________________
Katrina oil spill: Until the 2010 BP Gulf oil disaster, Katrina was the second worst oil spill in US history after Exxon
Valdez. The
oil pollution in the
wake of Hurricane Katrina could be among the worst recorded in North
America,
officials trying to coordinate the clean-up say. The US coastguard,
which is
responsible for the marine environment, said more than 6.5 million
gallons of
crude oil had been spilt in at least seven major incidents. The
previous worst
spill in US waters was the 11m gallons in Alaskan waters from the Exxon
Valdez
in 1989. The Katrina figure does not include petrol
and oil spilt from up
to 250,000 cars which have been submerged, or that spilt from hundreds
of
petrol stations. The coastguard says it has received almost 400 reports
of
spills, the vast majority of which have not been
assessed. link
Hurricane Ike -
According to Lars Herbst,
regional director for the Minerals Management Service, Hurricane Ike
“appears
to have destroyed a number of oil production platforms and
damaged some
of the pipelines in the Gulf of Mexico. Federal officials agreed at
least 10
production platforms have been destroyed by the storm, and possibly
many more. link Science Direct analyses the damage caused by the two hurricanes (Katrina and Rita) on the offshore oil and gas
industry.
November 2012: Cautious renewal of offshore drilling in Alaska and Gulf. The Obama
administration cautiously offered up more areas in the Gulf of Mexico and off
Alaska's coast to oil and gas drilling but didn't go far enough to satisfy
Republicans. Interior Secretary Ken Salazar unveiled a proposal to hold 15
lease sales for areas in the Gulf of Mexico, including two in the eastern Gulf,
and three off Alaska's coast in the time frame from 2012 to 2017. The sales off
Alaska, where native groups and environmentalists have objected to drilling,
would be the first since 2008. They would be held late in the five-year time
frame to allow for scientific evaluations in the Chukchi and Beaufort Seas,
which Interior officials called a "frontier" for drilling. And they
would be targeted to avoid areas with cultural and environmental sensitivities,
officials said. link
September 2011: The race for oil in the Arctic. The
world's oil companies are now turning to the Far North as supplies elsewhere
across the globe start to run out or become harder to extract, and both the
potential profits from Arctic oil, and the fears about the damage that
extracting it may do, are enormous. The area north of the Arctic Circle is
thought to contain as much as 160 billion barrels of oil, more than a quarter
of the world's undiscovered reserves. Some of it is under land, as in Alaska's
North Slope field, but large amounts of it are known to lie under the seabeds
of the Arctic Ocean and Baffin Bay off Greenland, which are ice-covered for all
or part of the year, depending on the region. It is this offshore oil which is
now the focus of a new exploration rush, with Shell and Exxon among
the strongest contenders, focusing on the Arctic Ocean itself, while the first
wells in the sea off Greenland are already being drilled by Edinburgh-based
Cairn Energy. Any serious oil spill in the ice of the Arctic, the "new
frontier" for oil exploration, is likely to be an uncontrollable
environmental disaster despoiling vast areas of the world's most untouched
ecosystem, one of the world's leading polar scientists has told The
Independent. Oil from an undersea leak will not only be very hard to deal with
in Arctic conditions, it will interact with the surface sea ice and become
absorbed in it, and will be transported by it for as much as 1,000 miles across
the ocean. link (See also: Unlocked
by melting ice-caps, the great polar oil rush has begun - link
October 2010: Another US oil problem on the horizon.
The US demand for oil has led to a connection with the tar sands oil of Alberta (see Keystone XL pipeline page for more on this). TransCanada
plans to build a $7 billion pipeline that carries tar
sands crude oil from the tar sands of Alberta to Gulf Coast refineries in Texas
and is vowing that the pipeline will be unparalleled on the safety front. Opponents argue how anybody can guarantee that a 36-inch diameter,
1,702-mile pipeline buried four feet deep and delivering up to 900,000 barrels
of heavy crude per day won’t leak. Although
Congress doesn’t have ultimate “yea” or “nay” power on this project, Keystone
XL is on their radar screens as federal legislators try to figure out if and
how they should strengthen the pipeline regulatory agency. A series of
summertime, headline-grabbing ruptures along the nation’s 2.3 million-mile network
of oil and gas pipeline, most notably in California and Michigan, has prompted legislators to
promote pipeline safety measures. link For more on Alberta tar sands oil, see Canada page Traditional oil corporations under pressure. National
governments and state-owned fossil fuel firms such as China National Petroleum
Corporation produce 93% of the world's oil. The formerly dominant supermajors (such as
ExxonMobil, BP, Royal Dutch Shell, Total), are now seeking out riskier and
riskier reserves, drilling in the ultra-deep waters of the Gulf of Mexico and
mapping the Arctic Ocean floor. In their continuing struggle to appease
investors, they've also become increasingly reliant on major oil sands
expansions, suggests groundbreaking new research detailed later in this story. link.
How much oil is off the Atlantic Coast? We really have no idea.
The entire East Coast has been off limits from all drilling-related
activity since 1981. That's the last time any data was collected on the
area, using seismic equipment that's outdated compared to today's
advanced methods. More accurate data is likely to lead to more accurate
drilling and fewer "dry wells" that don't produce oil. But it could
also revise downward how much we think is out there. The Interior
Department's Minerals Management Service (MMS) estimates there could be
as much as 10 billion barrels of oil and natural gas in the mid- and
south Atlantic. But that's only at a 5% level of confidence. Ask them
what they're 95% confident of, and the estimate drops to fewer than 2
billion barrels, or about 100 days of oil at our current rate. So, not
much. "We really don't know a lot about what's down there," Interior
Secretary Ken Salazar admits. "It may be nothing, it may be a lot.

June 2008: Andrew Leonard in Salon writes: John McCain and the offshore oil ruse. The truth is, we can probably make offshore drilling as safe as we reasonably
want it to be. Norway has
been drilling for decades in the North Sea with reasonably good
environmental results (notwithstanding the spillage of 24,000 barrels in December 2007). Then again, for an
example of how it can all go terribly wrong, visit Nigeria, where lax
environmental controls have resulted in a huge mess in the Niger Delta, and where rebel forces attacked
an offshore oil platform just this week. But drilling practices and technology have improved. With the
appropriate government oversight and regulation, it may be possible to drill off
the coasts of Florida and California without covering the beaches with sludge
and killing thousands of seabirds. Provided we acknowledge, of course, that a
few nasty hurricanes in Florida will make at least a little bit of mess, and an
earthquake in the wrong spot in California could be a slight problem. And
provided we are capable of following the example of Norway, where the government
and the people tell the oil company what to do and preventing energy industry being in charge of
policymaking. link Any
drilling would be minimal help According to the International
Energy Agency, if the federal moratorium on offshore drilling were
eliminated (and none of the states block drilling) and if exploration
and
development of resources in those areas begins in 2012, then
essentially no
extra oil would be recovered until 2020. From 2020 to 2030, the extra
oil
production averages about 150,000 barrels of oil a day. But of course
that's
not going to happen since California is not going to allow drilling off
its
coast. So we are almost certainly talking under 100,000 barrels a day
sometime
after 2020. more
| Oil subsidies / pollution |
Oil companies are already
sitting on 68 million acres of leases that they aren't even drilling?
Oil companies
already have access to nearly 80% of all American offshore oil
that is
technically recoverable. According to the US
Energy Information Administration, "access to the Pacific, Atlantic
and eastern Gulf regions would not have a significant impact on
domestic crude
oil and natural gas production or prices before 2030.” July 2010: An
examination of the American tax code indicates that oil production is
among the most heavily subsidized businesses, with tax breaks available
at virtually every stage of the exploration and extraction process. link April 2011: Energy companies underpaying by millions, perhaps billions. By law, energy companies must pay
one-sixth to one-eighth of the value of oil and gas obtained on public lands
and in federal waters off the nation's coasts. In practice, government auditors
and Interior's inspector general believe the industry is paying less than it
legally should. Exactly how much less is anybody's guess, but it is believed to
be at least hundreds of millions, and possibly tens of billions of dollars.
So flawed and complicated are Interior Department operations and records that
even auditors from the Government Accountability Office, the watchdog arm of
Congress, have been unable to figure out exactly how much has been lost to
taxpayers. link
The conventional
wisdom that the oil industry has been the major
beneficiary of
federal financial largess is correct. Between 1950 and 2006 the oil and
natural gas industries have garnered 60% of federal energy incentives
totaling $725 billion, with $335 billion in combined incentives going
to the oil industry. link
