Engineering Expert Witness On Gulf Spill

The color of the oil gushing from the main pipe in the Gulf of Mexico oil spill shows the underwater plume has changed in color from medium gray to black. Two scientists noticed the change, which oil company BP downplayed as a natural fluctuation that is not likely permanent.

However, engineering expert witness Robert Glenn Bea, Ph.D., P.E. at the University of California at Berkeley, says the color change may indicate the BP leak has hit a reservoir of more oil and less gas. Gas is less polluting because it evaporates. Bea has spent more than 55 years working and studying oil rigs.
