On the cover: We start our annual Downhole Geology issue with a computer-generated graphic that shows the configuration of a permanent in-well optical seismic system as being used by BP Norway and Weatherford at the Valhall Field -- a big step forward in securing effective 4-D data, and an example of how technology is helping geoscientists find success.
