    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.
•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
Nuclear decay       •Standard tracer technique in the petroleum industry to
detection            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

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.

                 beam. The quadrupole triplet is
                 to remove possible astigmatism
                 and also serves as one of the
                 focusing elements for the ion

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
           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.

  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.
