  3. Hydrogen Flame vs. Mass Spectrometer The best Flame-ionization chromatograph available being run in a side by side comparison to the DQ1000TM FID data DQMS data On this side we have the FID readings Note that C1 thru C5 are essentially a perfect overlay here – unlike real life. This is actually a great data set – note that the ratios are actually very slightly different after the show. On this side we have the DQ1000 readings Note that only C1 and C3 are positively deflected C3 simply does not improve at the same rate as C1, nor C5 at all, as the other machine would suggest. C9 C5 C3 C1 C10 C7(green) C5 C4 C3 C2 C1 “Air cut” scaling issue. Note that C1 is ¾ of value before show No “Air cut” issue. Note that C1 is about at value before show Lag error – not using pump strokes for lag method The older gear does not detect at all for the wetter hydrocarbons which are needed to do critical gas analysis.

  4. Example courtesy of Peter Moreland excerpted from his presentation at 2010 RMGS Peter Moreland Sr. Geologist Note that the gas data indicated lighter gas composition in the more fractured interval, and that the sections indicated through DQMS interpretation correlated to the FMI presentations very well. This DQMS interpretation was available to the operator within 24 hours of TD for their “packers plus” completion design. Crown Geochemistry, Inc.

  5. Prepared originally by Peter Moreland, Sr. Geologist at Bill Barrett Corp for RMAG 2010 – Thanks Peter! Note that the gas data indicated lighter gas composition in the more fractured interval, and that the sections indicated through DQMS interpretation correlated to the FMI presentations very well. This DQMS interpretation was available to the operator within 24 hours of TD for their “packers plus” completion design. Crown Geochemistry, Inc.

  6. Example data relative to published Ro Montgomery et al. 2005, published Ro map “Wetness” calculation using the equation Crown Geochemistry, Inc.

  7. Example data relative to published BTU contours “Wetness” calculation using the equation Crown Geochemistry, Inc.

  8. Example Wh data contours as marked Tarrant Parker Conforms to Natalie Givens and Hank Zhao’s BTU map for this region reasonably well. PS; remember this is a rough work done as a visual aid for an oral presentation, your mapping skills are probably more suitable to constructing any actual map. “Wetness” calculation using the equation X 100 Crown Geochemistry, Inc.
