• Crude oil contains associated hydrocarbon gases.
• When brought to surface the gases are released.
• Where there is no market for the gas the industry standard for disposal is flaring.
• Venting also occurs – releasing unburnt gases directly into the atmosphere.
• Alternatives include reinjection, on-site power generation, and transport to markets.
The Gas Flaring Issue
How Much Gas Is Flared?• A number of countries report
gas flaring volumes, but these are not all viewed as reliable.
• The World Bank Global Gas Flaring Reduction Initiative (GGFR) estimates that a 150 billion cubic meters (BCM) of gas is flared or vented per year.
• This is equivalent to 25% of US consumption.
• There is large uncertainty in the estimates since reporting is voluntary and the activity occurs primarily in remote locations.

Why Not Estimate Gas Flaring Volumes From Satellite Data?• Open combustion produces a unique
signature that should be detectable by satellite sensors.
• Systematic global observations of gas flaring from satellites could provide estimates free of corporate and national disclosure constraints.
The U.S. Air ForceDefense Meteorological Satellite Program (DMSP)Operational Linescan System (OLS) has aUnique capability to collect low-light imagery.

Pros and Cons of DMSP
• OLS sensor extremely sensitive to light emitted by gas flares.
• Global archive extending back to 1992.
• NGDC has standardized and largely automated annual product generation.
• Lighting detected from many other sources.
• No onboard calibration of visible band.
• Gas flares not detected in OLS thermal band data.

• Indonesia 3.5 3.23 3.39• China NA 2.50 2.23• Malaysia NA 1.95 2.07• India NA 0.78 0.75• Vietnam NA 0.67 0.68• PNG NA 0.31 0.37• Thailand NA 0.24 0.21• Brunei NA 0.118 0.119• Philippines NA 0.064 0.045• Myanmar NA 0.036 0.024
Conclusions• The satellite data estimate of global gas flaring
volumes is 190-199 BCM in 2004.• This is about 30% higher than the GGFR
estimate of 150 BCM.• Russia has the largest flaring – more than 30%
of the global total.• Indonesia, China, and Malaysia have the largest
amount of flaring in south and east Asia.• NGDC plans to extend the annual estimates
back to 1992 using the DMSP archive.
