Hydrates, an ice-like deposit formed by natural gas under extreme pressure, has been named as a cause of the explosion and sinking of the BP Deepwater Horizon rig two weeks ago. But it may also be an important future source of fossil fuels, writes Tamsin Carlisle
A type of ice-like gas deposit is emerging as a major safety concern for deepwater drilling as it hampers BP's struggle to shut down an oil leak from a stricken well in the Gulf of Mexico.
Natural gas hydrates, which occur mostly in sediments at the bottom of the ocean, have been implicated in the April 20 well blowout and explosion that sank the Deepwater Horizon drilling platform.
There are two main dangers: heat destabilises hydrates, sometimes with explosive results; and the high pressure found deep underwater is likely to lead to ruptured pipes and valve malfunctions, allowing plugs of hydrates to clog up the works.
"There was concern at this location for gas hydrates," says Robert Bea, an offshore risk assessment expert and professor at the University of California, Berkeley, who suspects hydrates were the root cause of the blowout at BP's Macondo well off the coast of Louisiana.
"The deeper the water, the greater the pressure, which when high enough can keep hydrates stable below the sea floor."
Hydrates clogging the pores in sediments below the ocean floor can form seals that trap conventional gas and oil in underlying rock layers over geological time. That can make the deepwater zones where hydrates form especially tempting targets for drilling, as oil companies move their search into deeper waters.
On Friday, another deepwater drilling platform sank, this time off the coast of Venezuela where an international consortium is developing the country's biggest gas discovery. The cause of that accident is not known.
Prof Bea, who has extensive access to BP documents on the US incident, says drillers encountered an unexpected "kick" of gas pressure a month before the blowout, suggesting that hot fluids from deep underground had released gas from hydrate crystals in the well bore. The gas kick was powerful enough to temporarily suspend drilling as a precaution.
Hydrates later stymied BP's efforts to use a 100-tonne steel and concrete box to trap the estimated 5,000 barrels of oil a day that was leaking from the Macondo well.
The problem was the formation of "jelly-like" hydrate crystals near the top of the container, which blocked the pipe through which the oil would have been pumped to the surface.
Now BP is using a fleet of 12 mini robot submarines to try to thread a pipe directly into the wellhead under 1,500 metres of water. The juncture would need to be perfectly sealed to prevent water from entering the pipe and allowing more hydrate crystals to form as the oil is pumped to a tanker at the surface.
"It's never been done before in water that deep," Doug Suttles, the chief operating officer for BP, said on Friday.
As a back-up, the company is preparing a smaller container known as a "top hat" for lowering over the wellhead. In theory, the smaller structure could be kept free of hydrates by injecting methanol to act as antifreeze.
Halliburton, the oilfield services firm that was responsible for cementing the Macondo well to help convert it from exploration to oil production, last year gave a presentation highlighting the risks from hydrates for deepwater jobs.
"Gas flow may occur after a cement job in the deepwater environment that contains major hydrate zones," Halliburton said. "Destabilisation of hydrates after the cement job is confirmed by downhole cameras."
But the sheer concentrations of gas trapped in hydrates, which leads to their explosive behaviour when the crystals fall apart, also means they could be an important future source of fossil fuel.
BP is investigating the possibility at a project in Alaska, where temperatures are low enough for hydrates to form onshore in the permafrost beneath the Arctic tundra.
Japan and India, which both lack sufficient conventional oil and gas resources to fuel their large economies, are also assessing prospects for gas production from hydrates in their offshore waters, as are established northern gas exporters such as Russia and Canada.
The recent Gulf of Mexico tragedy may seem very far away from the Middle East, which still has the biggest concentration of the world's conventional oil and gas resources.
Yet the planet's biggest gas hydrate deposits may lie deep in the Arabian Sea, according to recent joint Indian and US government field studies.

Mane points for safe home colouring
- Natural and grey hair takes colour differently than chemically treated hair
- Taking hair from a dark to a light colour should involve a slow transition through warmer stages of colour
- When choosing a colour (especially a lighter tone), allow for a natural lift of warmth
- Most modern hair colours are technique-based, in that they require a confident hand and taught skills
- If you decide to be brave and go for it, seek professional advice and use a semi-permanent colour

Real estate tokenisation project
Dubai launched the pilot phase of its real estate tokenisation project last month.
The initiative focuses on converting real estate assets into digital tokens recorded on blockchain technology and helps in streamlining the process of buying, selling and investing, the Dubai Land Department said.
Dubai’s real estate tokenisation market is projected to reach Dh60 billion ($16.33 billion) by 2033, representing 7 per cent of the emirate’s total property transactions, according to the DLD.

Mercer, the investment consulting arm of US services company Marsh & McLennan, expects its wealth division to at least double its assets under management (AUM) in the Middle East as wealth in the region continues to grow despite economic headwinds, a company official said.
Mercer Wealth, which globally has $160 billion in AUM, plans to boost its AUM in the region to $2-$3bn in the next 2-3 years from the present $1bn, said Yasir AbuShaban, a Dubai-based principal with Mercer Wealth.
“Within the next two to three years, we are looking at reaching $2 to $3 billion as a conservative estimate and we do see an opportunity to do so,” said Mr AbuShaban.
Mercer does not directly make investments, but allocates clients’ money they have discretion to, to professional asset managers. They also provide advice to clients.
“We have buying power. We can negotiate on their (client’s) behalf with asset managers to provide them lower fees than they otherwise would have to get on their own,” he added.
Mercer Wealth’s clients include sovereign wealth funds, family offices, and insurance companies among others.
From its office in Dubai, Mercer also looks after Africa, India and Turkey, where they also see opportunity for growth.
Wealth creation in Middle East and Africa (MEA) grew 8.5 per cent to $8.1 trillion last year from $7.5tn in 2015, higher than last year’s global average of 6 per cent and the second-highest growth in a region after Asia-Pacific which grew 9.9 per cent, according to consultancy Boston Consulting Group (BCG). In the region, where wealth grew just 1.9 per cent in 2015 compared with 2014, a pickup in oil prices has helped in wealth generation.
BCG is forecasting MEA wealth will rise to $12tn by 2021, growing at an annual average of 8 per cent.
Drivers of wealth generation in the region will be split evenly between new wealth creation and growth of performance of existing assets, according to BCG.
Another general trend in the region is clients’ looking for a comprehensive approach to investing, according to Mr AbuShaban.
“Institutional investors or some of the families are seeing a slowdown in the available capital they have to invest and in that sense they are looking at optimizing the way they manage their portfolios and making sure they are not investing haphazardly and different parts of their investment are working together,” said Mr AbuShaban.
Some clients also have a higher appetite for risk, given the low interest-rate environment that does not provide enough yield for some institutional investors. These clients are keen to invest in illiquid assets, such as private equity and infrastructure.
“What we have seen is a desire for higher returns in what has been a low-return environment specifically in various fixed income or bonds,” he said.
“In this environment, we have seen a de facto increase in the risk that clients are taking in things like illiquid investments, private equity investments, infrastructure and private debt, those kind of investments were higher illiquidity results in incrementally higher returns.”
The Abu Dhabi Investment Authority, one of the largest sovereign wealth funds, said in its 2016 report that has gradually increased its exposure in direct private equity and private credit transactions, mainly in Asian markets and especially in China and India. The authority’s private equity department focused on structured equities owing to “their defensive characteristics.”

The smuggler
Eldarir had arrived at JFK in January 2020 with three suitcases, containing goods he valued at $300, when he was directed to a search area.
Officers found 41 gold artefacts among the bags, including amulets from a funerary set which prepared the deceased for the afterlife.
Also found was a cartouche of a Ptolemaic king on a relief that was originally part of a royal building or temple.
The largest single group of items found in Eldarir’s cases were 400 shabtis, or figurines.
Khouli conviction
Khouli smuggled items into the US by making false declarations to customs about the country of origin and value of the items.
According to Immigration and Customs Enforcement, he provided “false provenances which stated that [two] Egyptian antiquities were part of a collection assembled by Khouli's father in Israel in the 1960s” when in fact “Khouli acquired the Egyptian antiquities from other dealers”.
He was sentenced to one year of probation, six months of home confinement and 200 hours of community service in 2012 after admitting buying and smuggling Egyptian antiquities, including coffins, funerary boats and limestone figures.
For sale
A number of other items said to come from the collection of Ezeldeen Taha Eldarir are currently or recently for sale.
Their provenance is described in near identical terms as the British Museum shabti: bought from Salahaddin Sirmali, "authenticated and appraised" by Hossen Rashed, then imported to the US in 1948.
