USGS Oil and Gas Resource Estimates Updated for the National Petroleum Reserve in Alaska (NPRA)

The U.S. Geological Survey estimates 896 million barrels of conventional, undiscovered oil and 53 trillion cubic feet of conventional, undiscovered non-associated gas within NPRA and adjacent state waters. The estimated volume of undiscovered oil is significantly lower than in 2002, when the USGS estimated there was 10.6 billion barrels of oil. The new estimate, roughly 10% of the 2002 estimate, is due primarily to the incorporation of new data from recent exploration drilling revealing gas occurrence rather than oil in much of NPRA.

The scandal around the oil spilt into the Gulf of Mexico does not subside. On Thursday, the information was released that U.S. authorities are preparing a lawsuit against the owner of the exploded BP platform, demanding compensation for damage caused by the leakage. Fines can reach $4,300 for each barrel of oil spilt in the waters of the Gulf, i.e., a total of approximately $17.6 billion.

WASHINGTON — Glaciers that detach from the seafloor and begin floating create larger icebergs than glaciers that stay on the sea floor, researchers have found. Floating glaciers also produce icebergs more erratically.

These new observations may help researchers better understand and predict iceberg production from glaciers and ice sheets, improving estimates of sea-level rise due to climate change.
