Over a month after the spill began, oil continues to gush into the Gulf of Mexico. The exact spill flow rate is uncertain –in part because BP has refused to allow independent scientists to perform accurate measurements– and is a matter of ongoing debate.

It is estimated that the resulting oil slick covers a surface area of at least 2,500 square miles (6,500 km2), although the exact size and location of the slick fluctuate from day to day depending on weather conditions. This animated image shows the fluctuations of the slick between May 21st and 24th.

As this environmental disaster continues, more than 22,000 people and 1,100 vessels are now involved in the onshore and offshore exercise to control the slick that is affecting approximately 65 miles of the Gulf coast.

It was reported this week that BP is recovering 40pc less oil than previously claimed as it prepares fourth attempt to halt leak. The oil giant admitted it was recovering less oil from a tube inserted into the mile-long pipeline that snapped after the Deepwater Horizon drilling rig exploded with the loss of 11 lives a month ago.

BP initially said that most of the estimated 5,000 barrels a day spewing out of the well was being collected and taken a mile to the surface but yesterday the company disclosed that the average daily recovery is running at just over 2,000 barrels.

BP conceded that the siphoning system involved “significant uncertainties” because of its novelty and said that it was impossible to “assure its success or put a definite timescale on its deployment”.

The use of a special tube to collect the oil is the third technique used by BP to control the flow after the failure to reactivate the blow out preventer and erect domes over the damaged seabed installations.

Now BP is pinning its hopes on operation “top kill” involving the injection of heavy drilling fluids to stop the flow and sealing the well with cement to end the nightmare. Engineers hope to start work on Wednesday while work continues on the slower process of drilling two relief wells.

May 11th is the 22nd day of a Gulf of Mexico oil spill that began with an explosion and fire on April 20 on the drilling rig Deepwater Horizon, owned by Transocean Ltd. and leased by BP PLC, which is in charge of cleanup and containment of the environmental disaster. The blast killed 11 workers.

Since then, oil has been pouring into the Gulf from a blown-out undersea well at about 210,000 gallons per day. At least 4 million gallons of oil have spilled since the explosion on the Deepwater Horizon. At that pace, the spill will surpass the 11 million gallons spilled in the Exxon Valdez disaster by Father’s Day.

The spill can be seen in the bottom right corner of the main image thumbnail, taken on May 7th, although it is best viewed by opening the full version due to the slight difference in color between the black oil and the navy blue gulf waters making it difficult to discern. Easier to see is the city of New Orleans to the northwest. However, the spill is easily spotted in the May 8th image details due to sun glint, causing it to appear much lighter than the surrounding waters. These images also show several parallel lines of clouds, an atmospheric phenomenon known as cloud streets, in the skies near the spill.

Top hats and junk shots are on the list of possible next steps to contain the gusher as BP, casting about after a 100-ton containment box failed, settles in for a long fight to stop its uncontrolled oil gusher a mile under the Gulf of Mexico. Engineers at BP PLC were wrestling with a shopping list of ways to plug the well or siphon off the spewing crude, including a smaller containment box, dubbed a top hat, and injecting debris into the well as a stopper, called a junk shot.

Helicopters dropped large sandbags in Louisiana to try to protect the Lafourche Parish marshes from the massive oil slick. The spill began creeping farther west of the Mississippi River last week. About 300, one-ton sandbags were expected to be used as a makeshift boom to protect the coast.

Battered by hurricanes, weakened by erosion and flood-control projects, the sprawling wetlands that nurture Gulf of Mexico marine life and buffer coastal sites from storm surges now face another stern test as a monster oil slick creeps ever closer. About 40 percent of the nation’s coastal wetlands are clumped along southern Louisiana, directly in the path of oil that was still gushing Monday from a ruptured underwater well. Roughly 4 million gallons have escaped in the three weeks since the oil rig explosion, and some is bearing down on the marshes as workers rush to lay protective boom.

BP  said Monday the spill has cost it $350 million so far for immediate response, containment efforts, commitments to the Gulf Coast states, as well as settlements and federal costs. The company did not speculate on the final bill, which most analysts expect to run into tens of billions of dollars.

Early finger-pointing began among companies involved in the oil rig explosion on the eve of the first congressional hearings into the accident. A top American executive for BP, Lamar McKay, said a critical safety device known as a blowout-preventer failed catastrophically. Separately, the owner of the rig off Louisiana’s coast said that BP managed it and was responsible for all work conducted at the site. A third company defended work that it performed on the deepwater oil well as “accepted industry practice” prior to last month’s explosion.
