The clariÞ ed paragraph is below. Quad GeometricsWith a profound understanding of the oceans and the atmosphere, Scripps has a lot to offer companies looking for ways to Þ nd and understand oil and gas deposits deep within the earth. With that same interest in mind, Quad Geometrics, LLC, another recent Scripps startup, was cofounded by Mark Zumberge, Ph.D., Research Geophysicist and head of the Gravity Lab at the Institute for Geophysics and Planetary Physics, to provide products and services that precisely measure key earth parameters such gravity, sound, pressure and vibration. Quad Geometrics takes technology developed through decades of research in the North Sea and other areas of intense oil and gas exploration, and brings it to the commercial marketplace. The instruments, licensed to Quad Geometrics by the University of California, San Diego, show changes in density under the seaß oor so drilling companies can see what?s happening underground as the oil and gas are pumped out. Changes in gravity measurements help extraction companies understand and maintain the balance between remaining oil and gas, empty space and the water used to back Þ ll the voids created by the pumping activity. Information on how much product remains in a reservoir is potentially worth hundreds of millions of dollars to these companies. Quad Geometrics? instruments can give a clear picture of the underground/underwater topography showing how much or how little viable product is sitting below the sea. As companies attempt to squeeze out the maximum from each well, such technologies can measure the reservoir to see if it?s cost effective to continue pumping or time to stop. Prof. Steven Constable directs the Marine Electromagnetism (EM) Laboratory at Scripps and established the Seaß oor Electromagnetic Methods Consortium (http://marineemlab.ucsd.edu/semc. html), which has attracted the support of leading oil and gas companies and specialized geophysical services providers that bene Þ t from the laboratory?s world-class expertise and access to cutting-edge instruments developed over decades by the EM Lab.
