Flow Simulation Approach to Estimating Oil and Gas Leakage Rate from the 2010 BP Macondo Well Blowout

On April 20, 2010, the Macondo Well drilled by BP from the Deepwater Horizon floating platform in the Gulf of Mexico suffered a blowout. Eleven people were killed by the explosion and fire on the platform before it sank into the sea. The resulting billowing oil and gas from the...

Global Climate and the Response of Oceanic Hydrate Accumulations

Matthew T. Reagan and George J. Moridis Earth Sciences Division, Lawrence Berkeley National Laboratory Scott M. Elliott, Mathew Maltrud, Philip W. Jones COSIM (Climate Ocean Sea Ice Modeling), Los Alamos National Laboratory Vast quantities of methane are trapped in oceanic hydrate deposits, with estimates of 3,000, 10,000, or even 74,000...

A Clearer Picture of Carbon Sequestration

Source: Berkeley Lab Computing Sciences Simulations Shed Light on Fate of Sequestered CO2 Despite progress in clean energy, Americans will continue to rely on fossil fuels for years to come. In fact, coal-, oil- and natural gas-fired power plants will generate 69 percent of U.S. electricity as late as 2035,...

CO2 as Cushion Gas for Compressed Air Energy Storage (CAES)

Curt Oldenburg and Lehua Pan Multiple approaches are needed to reduce global CO2 emissions to mitigate anthropogenic climate change. Among the approaches available are geologic carbon sequestration (GCS) and much greater use of renewable energy sources such as solar and wind. Because wind and solar energy are intermittent, energy storage...

Biological Carbon Sequestration: Fundamental Research on Biological Carbon Capture and Soil Carbon Stabilization (Margaret Torn)

Margaret Torn Sequestering carbon through biological capture of CO2 and stabilization in soils is one of the major climate-change-mitigation approaches under consideration by DOE and other agencies. Soils are a promising reservoir for sequestration, because soil organic carbon (SOC) residence times are up to tens of thousands of years (Torn...

Identifying and Predicting Climate Change Impacts on the Land-Based Components of the Water Cycle (Salve, R.)

Rohit Salve The major component of the global water cycle—the subsurface under hilly or mountainous regions found throughout the world—remains, to a large extent, an unmeasured zone. This zone, which extends from the surface to the underlying water table, defined here as the partially saturated fractured rock continuum (PSFRC), usually...

CC 2.0 Seminar Friday on Coupling Sequestration With Compressed Air Energy Storage

Source: LBNL TABL Curtis Oldenburg — head of the Geologic Carbon Sequestration Program in the Earth Sciences Division — will present the next CC 2.0 seminar Friday at 2 p.m. in Building 15-253 (User Support Building, adjacent to ALS). His talk, “Demonstration of the Super-Cushion Effect of Carbon,” looks at...

IR Spectroscopy with Superbright Light

Most analytical techniques can provide a snapshot of the average behavior of a group of cells. But as ESD’s Hoi-Ying N. Holman notes, these average snapshots can miss rare cells—those few that behave differently from the rest. Details about these cells often fail to rise above the noise of the...
