• Dispose of the oil at the surface during a well test.
• Avoid oil storage and pollution problems.
• Limit heat radiation on rigs.
• Burners are installed on
long booms to keep them a
safe distance from the rig.

• Principle: Atomization of well effluent -> reduction in fine
droplets
• Needs: -propane
-propane for pilots
-electricity for lodge boxes (spark plug)
-Schlumberger air compressors (do not use rig air)
-water mainly to prevent heat radiation
• Classified by number of combustion heads: determines
maximum oil flow rate

SAFETY ASPECTS FOR HANGING OFF A BOOM
•Standby boat in constant contact with by radio
•WT supervisor to get a work permit
•Everybody working on the boom wears a life vest
•Not compulsory to be attached with a safety harness
•Preferably this operation is carried out by daylight
•Consider weather situation
•Restrict the number of people on boom to TWO max.
