BP awards Colorado State University $5M to research technology for oil recovery from watered-out wells

Green Car Congress

Colorado State University has obtained a 5-year, $5-million grant from BP to study mechanisms involved with technology for oil recovery from “watered-out” wells. Upward of 70% of the petroleum can remain in the rock formations of many watered-out wells. 2000) Water Control. Bill Bailey et al. Oilfield Review.

New study confirms extensive gas leaks in the North Sea; recommends stricter guidelines for handling of abandoned wells

Green Car Congress

Researchers from the GEOMAR Helmholtz Center for Ocean Research Kiel have found that considerable quantities of the greenhouse gas methane escape uncontrolled into the water from abandoned oil and gas wells in the North Sea. On the basis of investigations directly on the seafloor it was possible to determine the amount of escaping gas.

Study finds methane emissions from coal mines ~50% higher than previously thought

Green Car Congress

The results have important implications for Earth’s climate because methane is about 25 times more powerful than carbon dioxide when it comes to warming the planet over a long period. Kholod said that when a closed mine is flooded, water stops methane from leaking almost completely within about seven years. —Nazar Kholod.

MIT Researchers Elucidate Model for Escape of Underground Methane in Frozen Regions; Current Rate of Escape May be Much Faster Than Earlier Believed

gas hydrate accumulations in ocean sediments and permafrost—escapes. Their findings, published online 29 August in the AGU Journal of Geophysical Research , also suggest that methane trapped under the ocean may already be escaping through vents in the sea floor at a much faster rate than previously believed.

Researchers find that abiotic methane can charge deepsea Arctic gas hydrates

Green Car Congress

It is estimated that up to 15,000 gigatonnes of carbon may be stored in the form of hydrates in the ocean floor, but this estimate is not accounting for abiotic methane. Methane produced by serpentinization can escape through cracks and faults, and end up at the ocean floor. So there is probably much more. —Johnson et al.

US DOE awards ~$5M to expand research on methane hydrates

Green Car Congress

When methane hydrates are “melted,” or exposed to pressure and temperature conditions outside those where the formations are stable, the solid crystalline lattice turns to liquid water, and the enclosed methane molecules are released as gas.
