SLIDE 2 Flaring is a widely used practice for the disposal of “associated gas” at oil production facilities in remote locations and poor countries. While flaring is a waste and there are h l i k technologies to make use of the gas, flaring is still better than venting venting.

SLIDE 21 Summary Summary
- Flames from gas flares can be detected in THEOS data
Flames from gas flares can be detected in THEOS data.
- The THEOS spectra of gas flares shows higher emission
in the near infrared (NIR) than in the visible bands. in the near infrared (NIR) than in the visible bands.
- This spectral pattern resembles the spectral signature
for green vegetation. But the contrast between the NIR g g and visible tends to be higher for gas flares than green vegetation.
- THEOS data collected at night would be capable of
discriminating gas flares and other combustion sources i h with ease.
