Financial Performance of Major Oil Companies, 2007-2011

"...Over the period 2007 to 2011, oil prices were volatile. They increased to a record peak in 2008, declined rapidly at the end of 2008 and early 2009, and increased through 2010, and remained
high during 2011. The total revenues and net incomes of the five major oil companies followed a
similar pattern. However, the companies’ production of both crude oil and natural gas, their two
key products, remained largely unchanged in the face of volatile prices, suggesting that for these
firms, market price and the production of key products are not closely related..."

World Oil Transit Chokepoints
"Chokepoints are narrow channels along widely used global sea routes, some so narrow that restrictions are placed on the size of vessel that can navigate through them. They are a critical part of global energy security due to the high volume of oil traded through their narrow straits."

Venezuela: Issues in the 111th Congress
"The United States traditionally has had close relations with Venezuela, a major supplier of foreign oil, but there has been friction in relations for almost a decade under the government of populist President Hugo Chávez. U.S. officials have expressed concerns about human rights, Venezuela’s military arms purchases, its relations with Cuba and Iran, and its efforts to export its brand of populism to other Latin American countries. Declining cooperation on anti-drug and antiterrorism efforts has also been a concern. In September 2008, bilateral relations worsened when President Chávez expelled the U.S. Ambassador to Venezuela, and the United States responded in kind. Under the Obama Administration, Venezuela and the United States reached an agreement
for the return of respective ambassadors in July 2009. While some observers were hopeful that
the return of ambassadors would mark an improvement in relations, this has not been the case.
The United States has continued to express concerns about the Venezuelan government’s
treatment of the news media and political opposition and about interference in the affairs
of other countries in the region.

Under the rule of President Chávez, first elected in 1998 and re-elected to a six-year term in
December 2006, Venezuela has undergone enormous political changes, with a new constitution
and unicameral legislature, and a new name for the country, the Bolivarian Republic of
Venezuela. Human rights organizations have expressed concerns about the deterioration of
democratic institutions and threats to freedom of expression under President Chávez. The
government benefitted from the rise in world oil prices, which sparked an economic boom and
allowed Chávez to increase expenditures on social programs associated with his populist agenda.
These programs have helped reduce poverty levels significantly, but the Venezuelan economy has
been hit hard by the global financial crisis and economic downturn..."

Employment in the Oil and Gas Well Drilling Industry
"Employment in the oil and gas well drilling industry accounted for 63,012 jobs in September 2009, which is the most recent period available from the Bureau of Labor Statistics (BLS) Quarterly Census of Employment and Wages (QCEW) program.

Gulf Coast employment in this industry is most concentrated in a number of Texas counties and Louisiana parishes. Drilling accounts for a much larger share of employment in these localities than is the case for the Nation as a whole.

Nearly a quarter (23.6 percent) of total U.S. Employment in this industry is in Harris County, Texas (Houston), which accounts for 14,881 jobs and 0.9 percent of private sector employment in that county. Drilling's share of Harris County employment is almost 15 times its share of the national total, also known as a location quotient..."

Oil and Gas Industry Fatal and Nonfatal Occupational Injuries
"Oil and gas industries are frequently in the news. Much of the time this news is related to changes in prices of oil and gas, which affect most consumers in one way or another. Another less frequent subject of media attention is when disasters strike, as in the offshore oil drilling platform explosion and fire on April 20, 2010, and previous incidents such as the Clearbrook, Minnesota pipeline fire in 2007 and the Texas City, Texas refinery explosion in 2005.

According to the North American Industry Classification System, the oil and gas extraction industry is classified in mining, as all mining industries are focused on extracting natural resources from the earth. Drilling oil and gas wells and support activities for oil and gas operations are classified under support activities for mining. Fatal injury data include oil and gas extraction, drilling oil and gas wells, and support activities for oil and gas extraction. Nonfatal injury and illness data only include drilling oil and gas wells.

Occupational injuries and fatalities associated with fires and explosions are rare events. The overall rate of injuries and illnesses with days away from work due to fires and explosions in all industries was 0.2 per 10,000 full-time workers in 2008, composed of 2,320 cases with days away from work. There were 174 fatal injuries due to fires and explosions in 2008, 18 of which were in the oil and gas industry..."

OPEC Revenue Fact Sheet
"Based on projections from the EIA December 2009 Short-Term Energy Outlook (STEO), members of the Organization of the Petroleum Exporting Countries (OPEC) could earn $575 billion of net oil export revenues in 2009 and $759 billion in 2010. Last year, OPEC earned $965 billion in net oil export revenues, a 41 percent increase from 2007. Saudi Arabia earned the largest share of these earnings, $284 billion, representing 29 percent of total OPEC revenues. On a per-capita basis, OPEC net oil export earning reached $2,671 in 2008, a 38 percent increase from 2007."

U.S. Crude Oil, Natural Gas, and Natural Gas Liquids Proved Reserves, 2008
"The Energy Information Administration's (EIA) estimates of proved reserves of natural gas and crude oil as of the end of 2008 tell very different stories about apparent changes in the availability of these two energy resources in the United States. Proved reserves are those volumes of oil and natural gas that geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions. Proved reserves of natural gas rose enough not only to replace production, but also to grow by almost 3 percent over 2007, largely due to continued development of unconventional gas from shales (see Table 1). In contrast, even though discoveries of crude oil rose for the third year in a row, proved reserves of crude oil fell by more than 10 percent. Under Securities and Exchange Commission (SEC) rules for determining reserves that have been in effect since 1982, operators assessed their 2008 reserves based on what they could produce with reasonable certainty at the market price on the last day of the year. Under updated SEC rules issued in 2008 that take effect in 2010, operators will instead use an average of first-day-of-the-month prices throughout the year, which is less sensitive to volatility in prices, in developing their reserves estimates. The SEC's new rules would have shown an increase in oil prices in 2008 compared to 2007, rather than the significant decline in the year-end 2008 price relative to the year-end 2007 price. Under the new rules, there would likely have been a smaller drop (or possibly even an increase) in crude oil proved reserves."

The Truth About America’s Energy: Big Oil Stockpiles Supplies and Pockets Profits — A Special Report by the Committee on Natural Resources Majority Staff
"While the oil industry and some Members of Congress argue that
opening more federal lands and waters would lead to lower gasoline prices,
the facts prove otherwise. The fact is that the Nation simply cannot drill its
way to lower prices at the pump. Other options, from greater energy
efficiencies to the development of alternative fuels, are essential to reducing
dependency on petroleum fuels and lowering fuel costs."

Oil Industry Profit Review 2007
"Increases in the price of crude oil that began in 2004 pushed the spot price of West Texas Intermediate (WTI), a key oil in determining market prices, to nearly $100 per barrel in the third quarter of 2007. Tight market conditions persisted through the remainder of 2007, with demand growth in China, India, and other parts of the developing world continuing. Uncertain supply related to political unrest in Nigeria, Venezuela, Iraq, and other places continued to threaten the market and contribute to a psychology that pushed up prices. The decline of the value of the U.S. dollar on world currency markets, as well as the investment strategies of financial firms on the oil futures markets, has also been identified by some as factors in the high price of oil. The profits of the five major integrated oil companies remained high in 2007, as they generally accounted for approximately 75% of both revenues and net incomes. For this group of firms, oil production led the way as the most profitable segment of the market, even though oil and gas production growth was not strong. The refining segment of the market performed relatively poorly."
