in Canada ... moves quickly to ensure
member Sam Epstein has his own story
to tell about what it was like at the World Trade Center
on Sept. 11. He was there.

this winter from an El Niño weather event?
Project: A new technology called dual
gradient drilling has the potential to revolutionize
at the wellsite? Geologists who keep
up to speed on developments involving drilling fluids
and new techniques can be enormously valuable.
resonance imaging can provide answers
to many questions regarding downhole geology.
magnetic resonance (NMR) continues
to be a valuable and technically evolving tool for downhole
and risk: Borehole imaging using microresistivity
images have become important, efficient, cost-effective tools
the secrets of the subsurface is always a tricky proposition, but
today's geologists are reaping the benefits of technological advances
to help in their mission -- developments that are covered in several
stories in this annual Downhole Geology issue of the EXPLORER. The
cover design, created by Rusty Johnson, features a drillsite photo,

based on dips from well bore and an interpreted structural model,
