Hurricane Threatens Gulf of Mexico

Low-pressure air in the southeastern United States will move toward the Gulf of Mexico, and potentially 50 percent turned into a tropical storm within 48 hours. According to the U.S. National Hurricane Center about the threat of bad weather in the area of the location of the worst oil spill in American history,According to weather forecasts, the low air pressure will cause the flow of warm water in the Gulf on Monday morning local time, and will be able to produce locally heavy rain and strong winds along the central Gulf Coast region.

Commander of the National Disaster Management Agency Thad Alen, who heads the government’s response in tackling the oil spill, said at the weekend, the activity of disposal wells that are designed to permanently block the oil wells will be finished after the giant energy company BP to end the period of testing and planning some time ago.Disposal wells by BP, the owner of the well which was leaked last week, also suspended because of bad weather.

Chronology of Gulf of Mexico oil spill

A drilling rig explosion on April 20 left 11 workers missing and presumed dead, and the rig’s subsequent collapse unleashed a major oil spill that threatens the ecosystems and economy of the U.S. Gulf of Mexico.Also threatened is the heart of U.S. energy production, as a giant, unprecedented underwater leak spreads oil across the northern Gulf of Mexico, threatening areas from Florida to points west of the of the Mississippi River.

President Barack Obama’s plans to widen offshore drilling have been suspended, and energy giant BP Plc (BP.N) (BP.L) faces another blow to its reputation and a multibillion-dollar bill for cleaning up the mess and paying damages.

Below is a chronology of the spill and its impact:

* April 20, 2010 – Explosion and fire on Transocean Ltd’s (RIG.N) (RIGN.S) drilling rig Deepwater Horizon licensed to BP; 11 workers missing, 17 injured. The rig was drilling in BP’s Macondo project 42 miles (68 km) southeast of Venice, Louisiana, beneath about 5,000 feet (1,525 metres) of water and 13,000 feet (4 km) under the seabed. A blowout preventer, intended to prevent release of crude oil, failed to activate.

* April 22 – The Deepwater Horizon rig, valued at more than $560 million, sinks and a five-mile long oil slick is seen.

* April 23 – The U.S. Coast Guard suspends search for missing workers.

* April 25 – The Coast Guard says remote underwater cameras detect the well is leaking 1,000 barrels of crude oil per day. The agency calls the leak a “very serious spill” that threatens ecosystems along the Gulf Coast. It approves a plan to have remote underwater vehicles activate a blowout preventer and stop leak, but the effort fails.

* April 26 – BP’s shares fall 2 percent on fears the cost of cleanup and legal claims will deal the London-based energy giant a heavy financial blow.

* April 27 – U.S. departments of Interior and Homeland Security announce joint investigation. Coast Guard says leaking crude may be set ablaze to slow the spread of oil in the Gulf.

* April 28 – The Coast Guard says the flow of oil is 5,000 barrels per day (bpd) (210,000 gallons/795,000 litres) — five times greater than first estimated. A controlled burn is held on the giant oil slick.

* April 29 – Obama pledges “every single available resource,” including the U.S. military, to contain the spill, which Homeland Security Secretary Janet Napolitano says is of “national significance.” Obama also says BP is responsible for the cleanup. Louisiana declares state of emergency due to the threat to the state’s natural resources.

* April 30 – An Obama aide says no drilling will be allowed in new areas, as the president had recently proposed, until the cause of the Deepwater Horizon accident is known.

* BP Chairman Tony Hayward says the company takes full responsibility and will pay all legitimate claims and the cost of the cleanup. The Interior Department orders safety inspections of all 30 deepwater drilling rigs and 47 deepwater production platforms.

* May 1 – Coast Guard says leak will affect the Gulf shore.

* May 2 – Obama visits the Gulf Coast to see cleanup efforts first hand. U.S. officials close areas affected by the spill to fishing for an initial period of 10 days. BP starts to drill a relief well alongside the failed well, a process that could take two to three months to complete.

* May 5 – A barge begins towing a 98-ton containment chamber to the site of the leak. BP says one of the three leaks has been shut off by capping a valve, but that would not cut the amount of oil gushing out.

* May 6 – Oil washes ashore on the Chandeleur Islands off the Louisiana coast, uninhabited barrier islands that are part of the Breton National Wildlife Refuge and important nesting and breeding areas for many bird species.

* May 7 – BP engineers use undersea robots to move the containment chamber over the larger of the two remaining leaks on the seabed. A fishing ban for federal waters off the Gulf is modified, expanded and extended to May 17.

* May 8 – BP’s containment dome hits a snag when a buildup of crystallized gas forces engineers to postpone efforts to place the chamber over the oil leak and siphon oil to the surface. “Tar balls” suspected to come from the leak wash up along a half-mile stretch of Dauphin Island, Alabama.

* May 9 – BP says it might try to plug the undersea leak by pumping materials such as shredded up tires and golf balls into the well at high pressure, a method called a “junk shot.”

* May 10 – Forecasts suggest the oil spill could move significantly west of the Mississippi River delta as brisk onshore winds prevail. BP announces plans to place a small containment dome, known as a “top hat,” over the blown out well to funnel oil to the surface.

* May 11 – Executives with BP, Transocean and Halliburton appear at congressional hearings in Washington, where Senators criticize their safety records. The executives blame each other’s companies for the explosion. The oil slick washes ashore on a third land mass: Louisiana’s Port Eads area, on the southern edge of the Mississippi Delta.(Reuters)

U.S. natural gas industry officials on Thursday defended a controversial drilling technique

U.S. natural gas industry officials on Thursday defended a controversial drilling technique known as hydraulic fracturing as the industry braces for possible new government regulations.Hydraulic fracturing injects millions of gallons of water, sand and a proprietary mix of chemicals up to two miles underground where it breaks open fissures in the gas-bearing shale to allow the gas to be extracted.Some environmental groups claim the technique, which is often referred to as “fracking”, is unsafe and threatens supplies of drinking water, but the industry claims its practice is safe.

“There is no known instance where fracking has contaminated someone’s drinking water,” said Will Brackett, the managing editor of the Powell Barnett Shale Newsletter, speaking on an industry panel sponsored by the George W. Bush Institute and Southern Methodist University’s Cox Maguire Energy Institute.Bush, the former U.S. president and Texas oil man, said more natural gas drilling would create more U.S. jobs. Bush did not touch on the hydraulic fracturing debate.

“When you explore for natural gas, when you develop natural gas, when you lay pipelines for natural gas, Americans are working,” Bush said in opening remarks to the conference.Earlier this month, the top U.S. environmental regulator said she was “very concerned” about the practice. The Environmental Protection Agency last week said it will conduct a study of drinking water impacts, which could mean new regulations on a booming area of the energy sector.

An industry scramble to develop vast shale deposits that are estimated to contain enough natural gas to meet U.S. needs for up to a century has brought drilling rigs within the limits of cities like Dallas and Fort Worth.

A bill in Congress would require gas companies to disclose the chemicals used in hydraulic fracturing and give the EPA oversight of the industry, which is now regulated by the states.

Industry officials dismissed any suggestion that their drilling practices were dangerous.”We have had some issues in less than half a dozen cases and they have been mostly mistakes and it is not clear that the issue is directly related to the fracking process itself,” said Randy Foutch, chairman and CEO of privately-held Laredo Petroleum.

Some residents who live near gas rigs in states from Pennsylvania to Wyoming say their water has become undrinkable since drilling companies fractured the wells and they complain of sickness and skin rashes after using the water.

Removing gas from shale rock accounts for 15 to 20 percent of U.S. natural gas production and provides a relatively clean energy source for the United States, which is trying to reduce its dependence on foreign oil.(Reuters)
