Methane and Hydrocarbon Emission Rates from Oil and Gas Production in the Province of Basra, South of Iraq

Abstract Petroleum deposits typically contain a gaseous component known as “associated gas”. If associated gas is not collected or used on-site, it may be flared vented byproduct of oil production. Flaring preferential to venting in terms global warming. oxidizes carbon and produces CO 2 , but by destroying methane other hydrocarbons, decreases the overall risk warming emissions. On 100-year time scale, fossil 36 times more potent than . The measurements were taken at six fields (AlTuba, Allhais, Artawi, North Rumaila, Nahran Omar, Majnoon) two power plants (Alnajebia plant Shatt Al-Basra). To measure concentrations direct measurement was for months. ANOVA test analyze results p ≤ 0.05 correlation between hydrocarbon concentrations, wind speed, temperature done. result showed that hydrocarbons found all stations, with different except Alnajebia Al-Basra first measurements, device did detect concentration. highest average Allhais which recorded 995, 598.15, 418.7, 358.89 279.13 ppm methane, ethane, propane, butane pentane respectively. lowest majnoon field 395, 238.8, 167.16, 142.2 111.4 relationship monthly speed positive.
