Oil rose over $137 Monday after traders calculated that Saudi Arabia's announced production increase will not be able to replace production disruptions in Nigeria, Bloomberg News reported.

Oil rose $2.20 to $137.56 per barrel in Monday mid-day trading. The other major energy commodities also rose on the news. Heating oil jumped 8 cents to $3.85 per gallon, unleaded gasoline gained about 4 cents to $3.47 per gallon, and natural gas climbed about 23 cents to $13.22 per million BTUs.

Attacks on a Royal Dutch Shell (NYSE: RDS.A) platform and a Chevron (NYSE: CVX) pipeline last week halted production of 300,000 barrels of oil per day from Nigeria, Bloomberg News reported. The Nigerian unrest easily offset Saudi Arabia's announcement, at the Jeddah summit it hosted, that it would pump an additional 200,000 barrels per day.

Oil's 'safety cushion' is low

Jim Dietz, independent energy trader, told BloggingStocks Monday, a weak dollar and speculator long positions have been factors in oil's more than 4-year bull market, but the No. 1 factor, in his interpretation, is the low 'safety cushion' between daily global oil supply and demand.

Oil surged $4.27 to $136.20 per barrel Friday after the dollar fell and reports confirmed that Israel had conducted a military exercise that analysts say rehearsed a potential bombing attack on nuclear targets in Iran, Bloomberg News reported Friday.

The other major energy commodities also surged Friday on the news. Heating oil jumped 11 cents to $3.82 per gallon, unleaded gasoline gained 8 cents to $3.43 per gallon, and natural gas climbed 26 cents to $13.12 per million BTUs.

Short-circuited oil sell-off

Under most circumstances, oil rises when the dollar falls, as holders of oil, which is priced in dollars, raise their prices to compensate for the reduced purchasing power of the dollar. The dollar Friday was set to record 3-cent weekly declines against the euro and British pound.

Further, geopolitical events re-entered the oil stage. Israel undertook a major military exercise earlier this month that American officials say appeared to be a rehearsal for a potential bombing attack on Iran's nuclear facilities, The New York Times reported Friday.

Alpha Natural (NYSE: ANR), an Appalachian coal producer with a market cap of $5.11 billion, closed at $72.73 Tuesday. Davenport & Company raised its rating to Buy with an $85 target price on May 27.

ANR overall option implied volatility of 65 is above its 26-week average of 58, suggesting larger price movement.

BBC news reported Saturday that militants in Nigeria have again sabotaged oil transfer infrastructure belonging to Royal Dutch Shell (NYSE: RDS A). This is the fifth incident of such attacks in recent weeks. The BBC report states: "Several previous ones have been blamed on supporters of the militant leader Henry Okah, who is currently awaiting trial on treason charges."

A Shell Oil spokesperson is quoted as stating that multiple oil delivery lines are affected and that some amount of oil has spilled into the environment. The company is undertaking oil containment measures and production volume has been reduced. Reuters News Service reported: "...the rebel Movement for the Emancipation of the Niger Delta (MEND) ... has already knocked 164,000 barrels a day off Shell's production in Nigeria with a pipeline bombing last month."

According to Reuters, local security forces are reporting that not just oil delivery lines have been affected. They claim that three oil wells and other equipment were also subjected to damage. Additionally, this news of sabotage comes on the heels of an eight day Nigerian labor strike against Exxon Mobil Corp. (NYSE: XOM). That strike ended this past Thursday and had temporarily cut that company's Nigerian oil production in half. And of course, with oil supply problems and concerns, oil prices have increased.

In what is sure to be only the latest event in a long case of protracted legal wrangling, a San Francisco federal appeals court has ordered Royal Dutch Shell Plc's (NYSE: RDS.A) vessels to stop all operations in the Beaufort and Chuckchi Seas. Environmental groups and Eskimo villages are seeking greater research into the effect drilling will have on marine wildlife in the region, and the judge agreed to give them time.

Shell isn't too happy. The company claims to have spent $200 million on the project already, including extensive research on the effect drilling will have on the environment, and has also formulated a plan to deal with oil spills. Of course, it's easy to be skeptical of an oil company's studies on environmental impact.

The Department of the Interior has supported drilling but, given the recent scandals involving global warming and political pressure on scientists, the department is not as high on credibility as it once was.

Given the amount of time it will take for any oil from the region to be brought to market, and the relatively small amount that is thought to be feasible for drilling, this probably won't have a material impact on energy prices anytime soon.
