The Dukhan anticline demonstrates a range in the extremity of folding of along its length, the folding of the northern part being more pronounced than the southern. Pastoralism has historically been dominant among the nomads of the area as many areas of Dukhan offer suitable grazing territory for camels . Once oil activities commenced, grazing camels often suffered ill-effects from oil pollution and litter. Some camels unknowingly consume residue and waste material left over from oil extraction and become sick. Furthermore, camels may come into contact with sensitive infrastructure, such as switches for oil wells and fences. Incidents have been recorded of camels causing leakages in oil wells, turning off oil wells and injuring themselves on such installations. It

In 1974 the Fahahil plant was commissioned to recover raw natural gas liquids (NGL) from associated gas (which is found in either dissolved in crude oil or as a ‘cap’ of gas above the oil). This milestone was followed in 1976 by

1935-472: Was reported in 1992 that oftentimes, camels crossing the roads around Dukhan were the cause of fatal motor accidents, particularly at night. In the early days of Dukhan's oil operations, livestock owners would be compensated by QatarEnergy for any incidents resulting in the death of their camels, however, this precedent was overruled in 1985, with the new official position stating that pastoralists were to be held responsible for their livestock. Common flora in
