Methane from BP oil spill eaten by microbes 2011-01-06T19:00:01Z In mid-May, academic scientists working in the Gulf started finding evidence that untold amounts of oil were spreading away from the wellhead and forming vast plumes some 1,200 metres below the surface. Newsmaker of the year: In the eye of the storm 2011-01-04T21:21:06.817Z The company did not succeed in halting the flow of oil and gas from the well until mid-July, when valves on a newly installed cap at the wellhead were closed. Relief Well Reaches Stricken BP Well 2010-09-17T14:40:00Z Still, Mr. Vidrine insisted on a second test that would be done slightly differently, measuring the upward flow in a smaller line running from the wellhead to the rig known as the “kill line.” Documents Fill in Gaps in Narrative on Oil Rig Blast 2010-09-08T02:50:00Z So the water at the wellhead still contains some of the water that’s been there over the last couple months.” Methane From BP Spill Goes Missing 2011-01-07T15:23:00Z More than 4 million barrels of oil gushed into the Gulf until July 15, when a cap on the wellhead sealed off all flow. Report: BP probe to spread blame for spill 2010-09-07T23:54:00Z The first flashpoint was the question of how much oil was leaking from the wellhead and where it was going. Newsmaker of the year: In the eye of the storm 2011-01-04T21:21:06.817Z Plus, by the time it hits land, natural processes have weathered the oil, making it less toxic than when it first came gushing out of the wellhead. Hurricanes Katrina and Rita damaged Gulf wetlands and swamps 2010-08-31T04:00:00Z Below it is a subsea cityscape of pumps, pipes, valves, manifolds, wellheads and blowout preventers — all painted a bright yellow so as to be visible to the floodlights of the remote-controlled submarines that maintain it. Risk-Taking Rises as Oil Rigs in Gulf Drill Deeper 2010-08-30T02:20:00Z The captain maneuvered the ship close to the burning rig to be closer to the wellhead. Testimony: Response to gulf well explosion hurt by lack of gear 2010-08-24T20:00:00Z Early groups of researchers theorized that some of the oil might spread in underwater plumes—perhaps aided by the liberal application of chemical dispersants at the wellhead. Oil in the Gulf: There's More Than We Thought 2010-08-19T22:40:00Z The threat is greatest to spawning grounds in the vicinity of the wellhead, where the plumes are concentrated, with fisheries in the broader Gulf of Mexico unlikely to suffer an impact, Dr. Short said. Oil Plumes May Be More Toxic Than Thought, Scientists Warn 2010-08-18T20:25:00Z Federal and independent scientists agree that undersea plumes of microscopic oil droplets pose a threat to sea life, but likely only within a few miles of the wellhead. Scientists Tussle Over Gulf Oil Tally 2010-08-17T22:44:00Z The footprint of development will be about one-third of the original proposal; the number of wellheads where drilling will occur was cut by about 70 percent.

BP cements Gulf oil well ahead of permanent plug 2010-08-06T02:42:00Z The firmest number in the report is that 17 percent of the oil emerging from the wellhead was captured by various containment devices. Government Report on Gulf Oil Spill Stirs Debate 2010-08-05T01:59:00Z About 17% was removed after BP was finally able to attach a pipeline to the wellhead a mile below the surface of the sea and pump it on to ships. Gulf oil spill: US scientists reject talk of plumes and report 75% of slick has gone 2010-08-04T19:59:00Z The leak was discovered during final preparations for the "static kill" operation, which involves injecting heavy mud into the wellhead. In gulf, crews ready for 'static kill' attempt 2010-08-03T16:22:00Z The static kill starts at the top, firing the mud and possibly cement into the blowout preventer that sits on the wellhead. BP aims to plug gulf oil well for good with two-pronged 'kill' shot 2010-08-02T04:00:00Z The static kill starts at the top, firing the mud into the blowout preventer that sits on the wellhead.

Officials in gulf and BP resuming work on relief well 2010-07-26T04:00:00Z The temporary cap on the broken wellhead contained most of the oil during the evacuation. As storm dies down, crews hurry back to work on gulf relief well 2010-07-25T04:00:00Z The frenzied activity to try to plug the broken wellhead one mile below the waves reminds me of the very worst approaches to product development and branding strategy. Oil and Innovation 2010-07-23T22:00:00Z Subsurface oil was detected close to the wellhead, she said, but was highly dispersed at significant distances from the well. A Brighter Day for Gulf Fisheries 2010-07-23T18:12:00Z Before the relief well punctures Macondo, engineers may also—if the government allows them—pump some heavy mud down from the now-capped wellhead. BP and the gulf: After the leak 2010-07-22T11:21:00Z The real end to the drama at the wellhead may be a few weeks away. BP allowed to keep well shut amid concerns about seepage 2010-07-19T12:57:00Z As BP ended its string of futility and affixed a cap to the wellhead, the news comforted a battered American psyche, a counterpoint to a ceaseless narrative of plans going spectacularly awry. A Spill Into the Psyche, and a Respite 2010-07-17T20:14:00Z The test would shut the well by closing off valves on a tight-sealing cap that was installed at the wellhead, 5,000 feet down and a few miles from this Coast Guard cutter. Timing on Oil Well Test Remains Uncertain, BP Says 2010-07-14T15:06:00Z The new cap-and-seal stack is larger than the previous one and is bolted over the top of the wellhead rather than clamped loosely over it. BP oil spill: testing begins after installation of new containment cap 2010-07-13T09:20:00Z "Start at the source, a mile beneath the surface," he says of the ruptured wellhead, which is accessible only to remote-controlled submersibles. Thad Allen: Obama's Master of Disaster in the Gulf 2010-07-13T08:30:00Z Gulf of Mexico oil leak: the old cap on the wellhead was not stopping all the oil from flowing into the sea. BP oil spill: new cap 'successfully installed' on leaking well 2010-07-13T05:56:00Z Associated Press Oil continues to leak from the broken wellhead in this image from video provided by BP late Friday. BP Removes Old Cap 2010-07-11T20:10:00Z The leader, , a retired Coast Guard admiral said at a briefing in New Orleans that technicians would remove the containment cap at the top of the wellhead, perhaps as early as Saturday. BP Is Ready to Put Tighter Cap on Runaway Well 2010-07-09T19:36:00Z Both require laying flow lines, either flexible or hard steel piping, to connect the leaking well to existing wellheads on these older sites. BP Sets New Spill Target 2010-07-08T04:11:00Z The area around the leaking wellhead, nearly 50 miles off the Louisiana coast, was buffeted Tuesday by strong, 20-knot winds and resulting waves that topped five feet high Tuesday. Oil in Lake Pontchartrain stokes worries in New Orleans 2010-07-07T01:26:00Z A Whale is being tested close to the wellhead because officials believe it will be most effective where the oil is thickest rather than closer to shore. Faith in BP cleanup rests on giant tanker 2010-07-04T16:09:00Z High waves at the well site delayed surface work to prepare for the next phase of BP’s system to collect oil at the wellhead, said Toby Odone, a company spokesman. Winds From Tropical Storm Disrupt Spill Cleanup 2010-06-30T01:12:00Z The backup plan would involve continuing to collect the oil through several systems at the wellhead and pumping it through a subsea pipeline to an existing production platform at least several miles away. BP Discussing a Backup Strategy to Plug Well 2010-06-29T01:46:00Z But the use of such large volumes of dispersant, and its application in a novel setting like the wellhead, constitute an experiment of epic proportions. How Much Has Spilled, and How Far? Seeking Answers as Questions Mount 2010-06-26T01:52:00Z Containment efforts continued at the wellhead after a temporary shutdown on Sunday that showed the improvised oil recapture system’s vulnerability to weather. Feinberg Says Faster Claim Payment Is Needed as Spill Cost to BP Tops $2 Billion 2010-06-21T19:50:00Z But although that represents "a significant improvement," there is still oil and gas surging from around a containment cap on the damaged BP wellhead, Allen said. Containment system capturing some gushing oil in gulf faces uncertain future 2010-06-18T15:50:00Z An estimated 73.5 million to 126 million gallons of oil has come out of the breached wellhead, whether into the water or captured. "I'm not stonewalling" 2010-06-18T13:15:00Z The majority, said the company, was lost through two incidents – one in which the firm claims that thieves damaged a wellhead at its Odidi field and another where militants bombed the trans-Escravos pipeline. Oil companies under attack 2010-06-15T17:45:00Z The method involves pumping oil from the busted wellhead to a special ship on the surface, where it will be burned off rather than collected. Obama will order BP to hand over control of oil spill damage claims 2010-06-15T15:27:00Z Allen said the pumping of oil and natural gas from a damaged wellhead deep in the gulf continues apace. Administration: BP agrees to expedite oil spill claim payments 2010-06-10T18:53:00Z Thad W.

Salazar defends drilling moratorium, Allen cites containment progress 2010-06-09T16:03:00Z The University of Georgia-led team of scientists tracked the plume from three-quarters of a mile to nearly 14 miles from the damaged BP wellhead. NOAA: Presence of hydrocarbons found deep in gulf waters 2010-06-08T20:19:00Z With no consensus among experts on how much oil is pouring from the wellhead, it is difficult — if not impossible — to assess the containment cap’s effectiveness. Rate of Oil Leak, Still Not Clear, Puts Doubt on BP 2010-06-08T01:56:00Z Thad W. Allen, the Coast Guard commander, said on “Face the Nation” on CBS that BP officials were working to secure the cap over the wellhead and to gradually increase the amount of oil recovered. Damage Will Go On After Well Is Plugged, Admiral Says 2010-06-07T01:09:00Z The oil is being collected in the funnel-like cap and then ushered up to the surface, where it is collected in a tanker called the Discoverer Enterprise sitting above the wellhead. Gulf oil spill: Containment cap working well so far, says BP 2010-06-06T21:31:00Z The Q4000 was used for BP's "top kill" operation, in which engineers attempted to pump heavy mud and other debris into the wellhead to plug it and stop the gush of crude into the gulf. Salazar defends drilling moratorium, Allen cites containment progress 2010-06-09T16:03:00Z She said that based on "fingerprinting" of the oil, the samples taken 40 nautical miles northeast of the wellhead appeared to be from the BP oil spill. NOAA: Presence of hydrocarbons found deep in gulf waters 2010-06-08T20:19:00Z He said that video images from the wellhead showed a “curtain of oil” leaking from under the cap. Rate of Oil Leak, Still Not Clear, Puts Doubt on BP 2010-06-08T01:56:00Z But a few tense moments later the cap was successfully centered over the wellhead, 5,000 feet below the surface, then lowered half a foot to make a seal. BP Funneling Some of Leak to the Surface 2010-06-05T02:37:00Z Earlier Thursday, 20-foot-long shears were used to snip the damaged riser pipe at the wellhead, and technicians began to lower the cap over it. Obama Cancels Asia Trip as Concern on Spill Mounts 2010-06-04T05:20:00Z The national incident commander denied that the government was deliberately underestimating the flow of oil from the damaged wellhead. Salazar defends drilling moratorium, Allen cites containment progress 2010-06-09T16:03:00Z Technicians operating remote-controlled undersea robots managed to cut a riser pipe over the bleeding wellhead, a successful first step in BP's latest effort to contain the oil leak. BP Takes a First Step Toward Capping the Leak 2010-06-03T05:40:00Z Mr. Wells reiterated that a second collection system, involving hoses at the wellhead, would be implemented “by the middle of June.” Rate of Oil Leak, Still Not Clear, Puts Doubt on BP 2010-06-08T01:56:00Z At times during the process of preparing the wellhead to accept the cap and putting the cap into position, it seemed like this latest effort might prove as futile as the previous ones. BP Funneling Some of Leak to the Surface 2010-06-05T02:37:00Z That oil was not leaking at the wellhead is corroborated by the logs, though at the time a survey of the entire riser, which was still attached to the blowout preventer, had not been completed. Logs Show Coast Guard Saw Potential Threat Early 2010-06-04T01:05:00Z Using robotic submersibles to manipulate 20-foot-long shears, technicians successfully snipped the damaged riser pipe at the wellhead and prepared to lower the cap over it. Relief Wells Proceed During Efforts on Sea Bed 2010-06-03T23:31:00Z Disadvantage: Getting powerful enough magnets in place; only possible on a small part of the exposed wellhead, not under the seabed. Deepwater Horizon: Guardian web users' oil spill solutions 2010-06-03T19:37:00Z The diamond-laced wire saw was being used to cut the riser, the mile-long pipe that once ran from the wellhead up to the drilling rig and snaked along the seabed. Admiral Says Oil Pipe Is Cut, a Key Step in Halting Leak 2010-06-03T15:05:00Z A diamond-studded wire saw had stalled on Wednesday after cutting less than halfway through the damaged riser pipe atop the blowout preventer stack at the wellhead. BP Funneling Some of Leak to the Surface 2010-06-05T02:37:00Z But oil engineers say that dynamite or other conventional explosives risk destroying the wellhead so that the flow could never be plugged from the top. Nuclear Option on Gulf Oil Spill? No Way, U.S. Says 2010-06-03T03:40:00Z For this procedure to work, the original riser, the pipe that once ran from the wellhead up to the drilling rig and now lies broken and snaking along the sea floor, must be sheared off. Latest Effort to Stop Oil Flow Hits a Snag 2010-06-02T16:34:00Z With robotic submarines, the company will sever the leaking, kinked riser pipe that emerges from the top of the blowout preventer, the five-story-tall contraption on top of the wellhead. As 'top kill' effort fails, BP must fall back on oil spill containment strategy 2010-05-30T04:00:00Z At the wellhead, roughly a mile down, that translates into a pressure of more than one ton per square inch. Under the Waves, a Deep Unknown 2010-05-30T00:21:00Z The majority, said the company, was lost through two incidents – one in which the company claims that thieves damaged a wellhead at its Odidi field and another where militants bombed the Trans Escravos pipeline. Nigeria's agony dwarfs the Gulf oil spill. The US and Europe ignore it 2010-05-29T23:04:00Z Officials said the pumping process was showing signs of success in conjunction with "junk shot" injections of heavier blocking material, such as rubber, into the wellhead. Oil spill's latest developments 2010-05-29T04:00:00Z If the top kill works, BP officials said the well would be sealed with cement and they would also consider installing a new blowout preventer on the wellhead, as a safeguard. BP Prepares for ?Top Kill? Procedure to Contain Spill 2010-05-25T16:01:00Z Fires have to be extinguished, wellhead equipment repaired, gunk removed. Expert Is Confident of Gulf Oil Well?s Death 2010-05-24T15:55:00Z The industry robots working on the seabed around the wellhead need powerful lights. Under the Waves, a Deep Unknown 2010-05-30T00:21:00Z Yet the area around the Deepwater Horizon wellhead, nearly a mile below the surface of the Gulf of Mexico, is busting with activity—robotic activity. How Robots Help Stop the Gulf Oil Spill 2010-05-19T19:38:00Z Preparations continued on a plan to pump heavy drilling mud into the well through the blowout preventer, the safety device at the wellhead that failed during the accident. BP Reports Some Success in Capturing Leaking Oil 2010-05-17T15:48:00Z Engineers at the surface used robotic submarines to try to close valves on a massive apparatus called the blowout preventer, which sits atop the wellhead 5,000 feet below. Engineers trying multiple tactics in battle to plug oil well in Gulf of Mexico 2010-05-11T04:00:00Z Because of the pressure, temperature and remoteness of such deep water, preparations to seal the well have taken time, with the work at the wellhead done by robotic submersibles. Expert Is Confident of Gulf Oil Well?s Death 2010-05-24T15:55:00Z In so-called managed pressure drilling, the wellhead is sealed by a rotating rubber cone, creating a closed-loop mud circulation system that allows for more precise control over pressures. With Spill, Focus Turns to Well-Blocking System 2010-05-10T21:49:00Z The blowout preventer, which failed to stem the flow of oil when the wellhead erupted and is widely used throughout the industry, is likely to be declared not fit for purpose, he added.
