GUIDELINES FOR MANAGEMENT OF GREEN HOUSE GASES (GHG) 
AND FUGITIVE EMISSIONS FROM MIDSTREAM AND DOWNSTREAM 
PETROLEUM OPERATIONS IN NIGERIA 
e. GHG Intensity (Emission Intensity): 
GHG Intensity for 
a company is the sum of Midstream and/or Downstream petroleum 
preproduction and production GHG emissions during that year (in units of Kilogram 
(Kg) 
of carbon 
dioxide 
equivalents 
(COze)), 
divided 
by 
the 
company’s 
total 
production for that year in units of Barrels of oil equivalent (BOE). 
It is calculated as: 
GHG Intensity (Kg COze/BOE)= 
Total annual GHG emissions (Kg CO2e/year) 
Total annual Production (BOE/year) 
Where: Total Annual GHG Emissions is the Total GHG emissions in Kg COze for the year 
BOE = Barrel of Oil Equivalent, 
f. 
Verification of Optical Gas Imaging (OGI) Camera 
i. 
Verification 
shall 
be performed 
by either the licensee 
or permit-holder, 
manufacturer, or a third-party accredited by the Authority. 
ii. 
Initial verification shall entail confirmation that the camera has the potential 
of imaging 
gases 
in 
the 
spectral 
range 
for 
the 
highest concentration 
compound in the potential fugitive emissions and 
ii. 
The OGI camera shall have the potential 
of imaging 
a gas that 
is half 
methane, half propane at a concentration of less than or equal t010,000 
ppm at a flow rate greater than or equal to 60g/hr from a quarter inch 
diameter orifice.
