aims of the project and approach
Aims of the project and approach

Noble gases are being used as tracers to measure the structure of gas and oil deposits. Due to their chemical inertness, they offer the advantage that they do not react with the environment with which they are in contact. In standard commercial applications long lived isotopes and nuclear decay counting are being used. Our research will employ stable isotopes, which are environmentally accepted.

The novelty in our present approach is that it uses optical detection for noble gases. In particular for krypton (Kr) it relies in using several narrow banded (1 MHz) cw-lasers to excite the rare isotope ions (signal ions) to a high Rydberg level, followed by field ionization and energy discrimination for their detection. We showed that this scheme can be implemented with about 20% total efficiency for 85Kr; it works equally well for all the stable Kr and other noble gas isotopes.

motivation
Motivation
  • A need to analyze well gas samples from the Northfield (Dr. Fahes) for rare noble gas isotopes.
  • Tracer techniques are relatively cheap and informative for reservoir structure characterization.
  • Allows fast diagnostics of gas/water breakthroughs and plug off efficiency by detecting the migration velocity of the tracers.
  • The total selectivity is made up as the product of selectivities of the mass separator and of the two laser excitation steps namely
  • Stotal = Smass separator • Slaser1 • Slaser2 = 10-3 • 10-4 • 10-4 = 10-11
comparison of main detection techniques
Comparison of main detection techniques
  • Standard tracer technique in the petroleum industry to
  • assess size, porosity, connectivity and other important
  • properties of a reservoir
  • Inject 20 to 40 Curie of 85Kr into a central well
  • Using decay counting measure the speed and extend of
  • spike migration by sampling surrounding wells
  • In a large fields nuclear decay counting runs out of
  • sensitivity due to diifusion

detection

Optical detection

  • About 3 orders of magnitude more sensitive [proven
  • by our on-line work at RIKEN (Japan), TRIUMF
  • (Canada), Oak Ridge National Lab (USA)]
  • Possible use of rare stable isotopes (Kr, Ar, etc.)
  • Enviromentally friendly
  • No safe guarding for nuclear polution
  • Large amounts of tracer gas can be safely injected
  • Availability of several tracer gases provides the opportunity for detailed reservoir characterization.

Source and open beamline segments showing the bending capacitors and the quadrupole triplet. The bending capacitors are for overlapping the ion beam on axis with the laser beam. The quadrupole triplet is to remove possible astigmatism and also serves as one of the focusing elements for the ion beam (does not contain a magnet for mass separation and field ionization region).

Director, Institute for Rare Isotope Measurements, and Research Professor, Departments of Geological Sciences, and Physics and Astronomy at the University of Tennessee.

The Institute for Rare Isotopes Measurements (IRIM) explores extremely sensitive analytical techniques using multiple lasers that make the detection of only a few atoms in a sample feasible.

Collaborations with researchers word-wide to studies of very old groundwater, contaminant transport and modern groundwater recharge, age-dating of polar ice sheets, and to studies of isotopic signatures in minute mineral grains in meteorites and presolar dust grains to understand the formation and early history of our solar system.

Dr. Thonnard measured the 81Kr concentration in groundwater to better understand the flow, recharge and potential for contaminant incursion in a major regional aquifer system. The many instruments in his laboratory include four mass spectrometers, two multi-wavelength laser systems, water and gas processing systems, and lots of vacuum and electronic systems.

Particular interest for the current work presents expertise of Dr. Thonnard in purification of gas and oil samples with tracer isotopes.

the major future stages of the project
The major future stages of the project

Spring 2008: The PI (Schuessler) and TAMU coop Industrial Engineering student Ricardo Nava are at TAMU Qatar to install the first half of the collinear fast beam apparatus, which is ready for shipping to Doha. Professor Fahes has reservoir gas which is evaluated fo rare noble gas isotopes for possible tracer use. Professor Nasrabadi uses his expertise to simulate tracer prorogation in a reservoir. Professor Rudolph Lorentz applies data computations and numerical solutions procedures to solving reservoir simulations with differential equations. Professor Samia Jones contributes to statistics and data evaluation.

June-December 2009: A postdoc under supervision of the PI and Profs. Fahes and Nasrabadi will will further develop the collinear fast beam apparatus and work with it based on the equipment that was already setup.

February to May 2010: By this time and the field ionization part of the collinear fast beam apparatus has also been completed in the TAMU machine shop and has been shipped to Doha by TAMU. The field ionization and energy discrimination stages will be added. Also a simple laser system will be operational.

June to December 2010: We will order the remaining equipment items to be shipped directly to Doha. They will be installed into the analytical instrument. The collaborating professors, postdoctoral researchers, and students will start to use the system to process tracer samples at TAMU-Qatar.
