The N2 content of North Slope gases as a function of depth, stratigraphic sequence, and the occurrence of samples within known fields or in non-field wells

Figure 6. The N₂ content of North Slope gases as a function of depth, stratigraphic sequence, and the occurrence of samples within known fields or in non-field wells. The vertical line at 4 mole % N₂ provides a visual reference to distinguish high N₂ content samples from the more frequent low values that are typical of oil field gases.
