Oil and Gas: Supply Issues After Katrina
Robert L. Bamberger and Lawrence Kumins
Resources, Science, and Industry Division
Summary
Hurricane Katrina made landfall on August 29, 2005, leaving behind considerable
devastation. Some onshore refineries were shut down in advance of the storm; others
remain down now because of the widespread interruption of electric power and flooding.
Assessment of damage to oil and gas production rigs, as well as refineries, continues.
Some operating refineries whose crude supply has been interrupted are borrowing crude
from the Strategic Petroleum Reserve (SPR). On September 2, the International Energy
Agency (IEA) announced a coordinated drawdown of European and Asian stocks
totaling 60 million barrels to be released at the rate of 2 million barrels daily. Some
refineries have resumed operation, but at reduced runs. A number of major refineries
remain shut. The Louisiana Offshore Oil Port (LOOP) resumed operation late
September 1, and is accepting crude oil imports. The Colonial pipeline, which supplies
refined products to regions of the South and Northeast, has resumed operation and is at
100% of pumping capacity. The industry advises that it may be months before the area’s
oil and gas production and refining are fully restored. Spot and futures prices for
gasoline and middle distillates rose sharply in the days following the storm, but prices
began to fall early the week of September 5. This report will be updated.
Hurricane Katrina shut down oil and gas production from the Outer Continental
Shelf in the Gulf of Mexico, the source for 25% of U.S. crude oil production. Several oil
refineries that provide a significant share of the nation’s refined petroleum products
remain shut down along the Gulf Coast in Louisiana and Mississippi. Much of the product
from Gulf refineries is transported by pipeline for the East Coast and upper Midwest.
Important to policymakers will be continuing information on the damage to production
facilities, refineries, and transport facilities and how soon they can be restored to
operation. Most of the information cited in this report is from the trade press and the
Energy Information Administration.
On August 31, Secretary of Energy Bodman announced that the Bush Administration
was authorizing releases of Strategic Petroleum Reserve (SPR) crude oil. Operating
refineries whose crude supply has been interrupted have requested to borrow roughly 9
million barrels. The release of SPR oil and the announcement on September 2 from the

crude and refined products calmed markets by early in the week of September 5. The first
of this supply should reach the United States by mid-September. However, recovery from
the hurricane’s effects will depend upon resumption of production and refining operations
in the Gulf, and the ability to transport petroleum products.1 Roughly 1.3 million barrels
of refining capacity in the Gulf remains completely shut down, but total capacity lost may
approach 2.0 million barrels. When refineries resume operation, runs are sharply reduced
and then increase over a number of days.
Factors Affecting Oil and Natural Gas Supply
! Outer Continental Shelf (OCS) Production. Natural gas and petroleum
production in the Western Gulf of Mexico is virtually halted. Eastern
Gulf output is seriously curtailed. About 1.0 million barrels per day
(mbd) of crude and 5.2 billion cubic feet per day (bcf/d) of gas output are
currently offline.2
! Postponement of Natural Gas Deliveries at Henry Hub. This is the
delivery point, located in Louisiana, for purchasers taking physical
delivery of gas traded on the New York Mercantile Exchange (NYMEX).
Trading was briefly interrupted following the hurricane, but the timing
of physical delivery of natural gas contracts is unclear. The Henry Hub
gas contract is an important pricing benchmark widely used in setting
prices nationwide.
! Lack of Alternative Gas Supplies. OCS natural gas supply losses are not
easily made up by imports because additional supply possibilities from
Canada and from liquefied natural gas (LNG) are limited. There is no
Strategic Petroleum Reserve (SPR) for gas. A short-term problem could
worsen if the shortage continues into the heating season.
! Crude Oil Imports via Louisiana Offshore Oil Port (LOOP). About 1
mbd of crude oil imports flow through this tanker offloading facility.
This constitutes roughly 5% of petroleum consumption.3 LOOP resumed
operation late September 2, delivering crude to an operating Exxon
refinery in Baton Rouge, Louisiana. On September 5, LOOP reported that
it was operating at full capacity. Other Gulf Coast ports through which
oil imports flow may not have yet resumed operation.
! Pipeline Transport of Crude Oil and Refined Products. Pipelines from
the Gulf to the Midwest and East Coast have been affected. The Colonial
Pipeline — serving the whole East Coast with refined products — was
operating at full capacity early in the week of September 5. Its capacity

is 2.4 million barreks per day. Because the pipeline was full when it went
down, deliveries of gasoline and middle distillates were immediate. The
Capline pipeline resumed operation on September 1 at a reduced rate of
720,000 b/d, pending restoration of full operation of LOOP, and is now
operating at 960,000 b/d, or 80% of its capacity.
! Product Imports and International Energy Agency (IEA) Response. On
September 2, the IEA initiated a coordinated stock drawdown of 60
million barrels of crude and refine product stocks from Europe and Asia.
Two million barrels daily will be released. Gasoline imports currently on
the water should begin reaching the United States by mid-September.4
The IEA has indicated a willingness to release strategic stocks held by
member countries if the situation warrants.
Refineries
Several major facilities in Louisiana and Mississippi are closed. Refineries in the
region are located in low-lying areas and have sustained some water damage. Roughly
1.3 million barrels of refining capacity in the Gulf remains completely shut down, but
total capacity lost may approach 2.0 million barrels. Some refineries anticipate resuming
operations within the next few weeks. Others still lack power and have water damage.
When refineries resume operation, runs are sharply reduced and increase over a number
of days.5 (See Table 1.) Electric power appears to have been restored to all but two
refineries in the New Orleans vicinity.6 Refiners are also concerned about staffing
facilities because employees have been scattered by the storm; there is both concern and
uncertainty whether some will return to the region. Chevron has placed an advertisement
asking employees to phone.7
Electric Power8
At the height of Katrina, it is estimated that 2.6 million customers lost power. Power
is now being restored. Inaccessibility due to flooding and saltwater damage to equipment
are major factors slowing restoration. Mississippi Power estimates that about 70% of its
8,000 miles of transmission and distribution lines will have to be repaired or replaced
because of Katrina — a process the utility estimates could take four weeks. Early in the
week of September 5, Mississippi Power had restored power to over 44% of its

customers.9 Entergy, which serves the greater New Orleans area, reports that a major
obstacle to restoring service is the lack of food and water for its repair crews, who are
sleeping in their trucks. Entergy reports that priority for crews includes restoring service
for pumping, sanitation, medical, and housing facilities.10 Power outages have hindered
or delayed the resumption of pipeline operations. The Louisiana Public Service
Commission is working with Entergy to assess the situation and provide guidance on
priorities. FEMA Region IV is working with Mississippi officials on the same subject.

Relaxation of Motor Fuel Standards11
On August 31, 2005, Environmental Protection Agency (EPA) Administrator
Stephen Johnson announced that EPA would temporarily waive certain gasoline and
diesel fuel standards through September 15, 2005, in order to help increase available fuel
supplies. For gasoline, EPA is waiving volatility standards that would otherwise prohibit
the sale of gasoline produced for northern states in the South, or the sale of “winter”
gasoline in the summer months. This waiver should allow gasoline normally prohibited
in certain areas to be transported to those areas in response to supply limitations. EPA is
also waiving sulfur standards for diesel fuel, so that fuel produced for non-road uses may
be legally used in highway vehicles. This waiver should help mitigate some of the
disruption in diesel fuel supplies.12
Gasoline and Distillate Inventories

As of August 26, the Energy Information Administration reported that U.S.
commercial gasoline inventories were 194 million barrels, near the lower bound of the
normal range. Minimum operating level is 170 million barrels, representing the point at
which localized shortages occur because the distribution system cannot be drawn down
further without hindering operations. At current consumption rates, this amounts to less
than three days of available supply.
The situation with middle distillates (heating oil and diesel fuel) is somewhat similar,
reflecting the normal seasonal build of stocks, now standing at 135 million barrels, the
equivalent of nearly nine days of available supplies.
As a result of Katrina, wholesale gasoline prices on the New York Mercantile
Exchange surged almost immediately, in anticipation of a shortage. At the beginning of
September, wholesale gasoline traded on the NYMEX briefly surged to $2.40 before
settling to $2.06/gallon on September 5. Pump prices also reached a new high of $3.06
nationwide, according to the American Automobile Association. Distillate prices
followed, albeit with a lower rate of increase. Following announcements of the use of SPR
crude and the coordinated international stock drawdown from IEA nations, prices
retreated early in the week of September 5.

Commercial Inventories of Crude Oil

Crude stocks were 321 million barrels on August 26, up from 285 million barrels
during the same period last year. Minimum operating level for crude is 270 million
barrels, suggesting that 51 million barrels might be available from existing inventories.
This could be used to offset the shortfall of OCS production and imports, if it were
located where it could be accessed by refiners seeking replacement crude. But it is not
clear that logistics would support this, nor is it clear how rapidly refining capacity to
utilize these inventories will be restored.13 New stock numbers should be available on
September 8.
Strategic Petroleum Reserve
On August 31, Secretary of Energy Bodman announced that the Administration was
authorizing loans of crude oil from the Strategic Petroleum Reserve. By September 6,
loans had been granted to six companies totaling roughly 12.5 million barrels.14 But as
noted above, the SPR will be of limited help in this situation if there is insufficient
refining capacity to turn its stocks of crude oil into gasoline or diesel fuel.
