BP, rig owner Transocean and well cement contractor Halliburton have blamed each other for the disaster.
In September, a government report on the spill found that BP, rig owner Transocean and well cement contractor Halliburton shared responsibility for the explosion, but BP was "ultimately responsible" for operations at the site.
Trinidad and Tobago is the leading Caribbean producer of oil and gas, and its economy is heavily dependent upon these resources but it also supplies manufactured goods, notably food products and beverages, as well as cement to the Caribbean region.
For all the attention given to technologies like horizontal drilling and hydraulic fracturing, some of the greatest gains to be made in reducing the environmental risks of natural-gas production come from simple things like the proper pouring of cement well casings and the proper handling of chemicals and wastewater, so that they do not spill or seep into streams or water supplies.
The solutions for -- the solution with the top kill, first in stabilizing the well with heavy drilling mud, ultimately would lead to the cement capping of that well.
If a stable column of mud has been set up in the well, keeping the oil at bay through its sheer weight, the next step would be to set cement in the well and seal it off permanently.

This technique, starving fires of oxygen and then instantly capping the well with mud and cement, remained his favourite.
Halliburton was contracted by BP to cement the well and had argued its contract protected the energy company from legal action resulting from its work.
From that point, it will take another few days to permanently seal the well with mud and cement from below in what's called a "bottom kill" procedure.
At this moment, Davy Jones has been cased to the bottom of the well, sealed with cement and temporarily abandoned so the rig could be moved 2.5 miles to the southwest to drill the second Davy Jones delineation well.
Allen said that would push the interception date -- which had been expected Thursday or Friday -- to sometime between Sunday and next Tuesday, weather permitting, at which point crews could begin the "bottom kill" procedure to permanently cement the well.
Halliburton said that the report "accurately places responsibility on BP as the well owner for its operational decisions, " which included using a heavy fluid designed to keep gas from entering the well, called drilling mud, that was "too light" and probably mixed with the cement at the bottom of the well, and drilling too narrow a well.
That could have been why Transocean was pushing to complete the cement plugs while the well was still weighted with mud.

The plan was to set cement plugs in the well, temporarily abandon it, and move the Deepwater Horizon off to a new drilling site within a couple days.
As in most oil states, Iraq's idea is to channel the crude oil wealth into the creation of refineries, steel mills, agriculture, cement factories, as well as sundry infrastructural programs--schools, hospitals, roads and the like.
The commission's 13 key points focused on tests done to check the cement used in the well, decisions made by BP when plugging the well and the actions of those at the company in the hours before the disaster aboard the Deepwater Horizon rig.
Dialog from the characters helps cement that attachment, as well as providing some comedic moments.
Monday's presentation kicked off a two-day hearing that is due to include reaction from BP, Transocean and Halliburton, the contractor which did the cement job on the Macondo well.
But others point out that CCS is able to eliminate CO2 production from industries such as cement and steel, as well as electricity generation, again through absorbing it from waste gases.
While many remember the failed blow-out preventer and bad judgement all-around, a sloppy cement job in the Macondo Well, meant to save a couple of days and a few hundred thousand dollars, failed.
According to Bartlit's letter, the cement was poured to stabilize the well on April 19 and 20.
The mud solidified into a cement like mass that caused the well to stop flowing and then really STOP FLOWING.

Then there is Halliburton, which was contracted to cement the production liner in the well casing, effectively sealing off the reservoir from the well bore.
With that leak sealed, the plan is to inject heavyweight "kill mud" into the lower part of the blowout preventer, followed by cement that will effectively entomb the well.
Halliburton ( HAL - news - people ), which was contracted to cement the production liner in the well casing, effectively sealing off the reservoir from the well bore.
Cemex makes one of the world's most basic products -- cement -- and makes it very well.
However, the letter said investigators were unsure if that fourth test was completed before the cement slurry was poured at the Macondo well, and that Halliburton reported the positive result to BP after the blowout.
Washington (CNN) -- Oil giant BP and contractor Halliburton knew of potential flaws in the cement slurry used to reinforce the oil well below the Deepwater Horizon rig before it exploded in April, according to a letter Thursday from the lead investigator for a federal probe of the Gulf oil disaster.
