Screen 3 Assumptions:

North Hargrave SWB

Calculations for Screen3- air dispersion modeling

Assume: GOR= 5 m3/m3

90% of gas breaking out of tank goes to flare- the rest stays in tank and goes through scrubber

flare stacks are 40 ft ( 12.2m tall)

tanks are 24 ft tall ( 7.3 m)

H2S: 0.0560 mole fraction and 80.7 g/m3 hydrogen sulfide (used highest of 2-23-12-27 well, 5-23-12-27 well and 4-23-12-27 battery analysis')
