EFD Field Trial of Dissolved Gas Sensor
Measuring concentrations of dissolved gases in ground water remains a challenging proposition. EFD is coordinating a test of a Raman spectroscopy downhole tool for this purpose. This technology is a offered by WellDog, a service company based in Laramie, Wyoming, offering services in the US and Australia. The Raman spectroscopy tool will be field-tested at a site located in an area known to have dissolved gas present in ground water.
"The Raman effect occurs when light scattering from a material excites the natural vibrational motion of the interatomic bonds in that material. During that excitation, the photons comprising the light lose a certain amount of energy and therefore change in color. By measuring the color of the resulting photons, Raman spectroscopy identifies the materials. By examining the number of photons at each color, Raman spectroscopy also measures the concentration of the materials."

article by Louise S. Durham
Airguns have long been the industry standard sound source used by crews to acquire seismic data in the marine environment offshore.
The driving mechanism for airguns is supplied by compressed air, and the devices create considerable noise when large volumes of air are emitted. These intense pulses of acoustic energy act as a signal, traveling downward through the water and ultimately triggering a series of refractions and reflections off the varied horizons present in the target subsurface area.
This popular and effective sound source technology has remained essentially static through the years.
Change, however, is afoot...

Welcome SMU to the EFD University Alliance!
The SMU Geothermal Lab was established in 1970 by Dr. David Blackwell. Research is the lifeblood of the SMU Geothermal Laboratory with a variety of ongoing geothermal resource projects specializing in thermal conductivity, heat flow and basin fluid-flow modeling. Our faculty, staff, and students strive to broaden the understanding and use of geothermal energy, from the simplest form - geothermal heat pumps for buildings, to the large-scale deployment of geothermal power plants providing energy for our cities. Our research also explores opportunities to integrate renewable geothermal projects in an oil & gas setting.

The EFD program, funded by federal, state and foreign government agencies, industry and environmental organizations, provides unbiased science to policy makers and identifies, develops and tests new technologies, processes and systems to reduce the environmental footprint associated with oil and gas activities, from well site selection through natural gas compression. The program, approximately $4 million per year, is engaged in research and technology transfer activities from the Western Slope of the Rockies to the Ukraine, and from the North Slope of Alaska to Columbia (South America). Research includes land, air and water issues, as well as public perception investigations. The program was honored with the Chairman's Stewards Award for Environmental Partnership at the 2009 Annual Meeting of the Interstate Oil and Gas Compact Commission.
