Cretaceous volcanic ash seeded U.S. oilfields

Petroleum and natural gas stores are often found amid rocks — particularly ashbeds — deposited during the Cretaceous, when dinosaurs roamed Earth and abundant volcanic arcs lined the edges of the continents.

Bubble accumulation could explain massive volcanic sulfur releases

The spectacular 1815 eruption of Indonesia’s Mount Tambora spewed large amounts of sulfur gases into the atmosphere, which formed fine sulfur-rich particles that blocked sunlight and lowered global temperatures by more than half a degree Celsius, causing famine and death on a global scale.

Above oil seeps, photosynthetic life flourishes

The direct effects of oil and gas releases in the ocean are typically negative — as in the case of 2010’s Deepwater Horizon oil well disaster, which devastated marine ecosystems in the Gulf of Mexico. But scientists have now found that when natural oil and gas seeps upwell toward the ocean’s surface, they can also carry nutrients such as nitrates and nitrites from the seafloor that feed communities of phytoplankton, which flourish as a result.

The Changing Face of Sudan

To say that things are changing in Sudan would be an understatement. With a referendum on secession set for Jan. 9, and expected to pass, and many issues to be negotiated between now and July 9 when the country’s peace agreement ends, a lot will change over the coming months. And everything hinges on Sudan’s most valuable product: oil.

Natural gas production linked to earthquakes in Texas

A saltwater disposal well, a part of the natural gas production process, may have been responsible for triggering a series of minor earthquakes in the Dallas-Fort Worth area of Texas in 2008, according to a recent study.

Of sounds and cetaceans: Quieting a noisy underwater world

Marine mammals live in a world of sound. In the open ocean, whales and dolphins depend on sound waves, using echolocation to navigate, find food, attract mates and communicate. But their clicks and calls are not the only noises underwater: Oil and gas exploration, seafloor mapping, and ship and submarine navigation have increased dramatically over the past few decades, making the world’s oceans noisier than ever.

Crystal Ball EARTH: Energy: A fool's look into the future

In the 1985 classic “Back to the Future,” Doc Brown, the mad scientist played by Christopher Lloyd, queries his time-traveling visitor, Marty McFly (Michael J. Fox), in 1955 about the future of America with the simple question of who was president. The answer of Ronald Reagan appeared astounding and ridiculous, as his name was on a movie poster at the time.

Crystal Ball EARTH: Energy: Oil and gas around the world

Energy is a combined product of natural resources, human ingenuity and economy; it is also an engine for economic and social development. This is truer now than ever before because the global economy is more integrated and populations are growing, and with that, competition, challenges and prospects are also rising.

Coal-to-liquids: Can fuel made from coal replace gasoline?

Amid all the attention to the converging of three energy-related crises — climate change, resource depletion and international extremism funded by the energy trade — a surprising energy choice keeps rearing its head: coal. That especially includes liquid fuels made from coal, which can be a substitute for gasoline, jet fuel and just about any other transportation fuel on which we currently rely.

As Green As It Gets: Algae Biofuels

It’s hard to think of a humbler organism than algae, or a less-likely prospect to become savior of our energy future. “Algae fuel” does not conjure up images of power, big business or high-tech gadgetry; it suggests a modest picture of a murky pond covered by a greasy, greenish film. But unassuming algae, some researchers think, have the potential to become the ultimate in “green” fuel, powering everything from cars to jets — and perhaps putting an end to one of the more bitter battles in the biofuels industry: the “food versus fuel” debate over how best to use arable lands.
