Citronelle, Alabama

==Geology==
Citronelle developed on what is known as the Citronelle Dome, a salt dome formation that is still rising, as shown by the radial drainage of streams away from the center. In 1955 oil was discovered in this geologic structure at a greater depth than had previously been considered as feasible. The Citronelle Dome was developed as among the first of many "deep" oil fields. The discovery well yielded oil from the [[Glen Rose Formation]] at a depth of {{convert|10879|ft}}.<ref>{{cite book| last1=Eaves| first1=Everett| editor1-last=Braunstein| editor1-first=Jules| title=Citronelle Oil Field, Mobile County, Alabama, in North American Oil and Gas Fields| date=1976| publisher=American Association of Petroleum Geologists| location=Tulsa| isbn=0891813004| pages=259–275}}</ref>

"Citronelle Dome is a giant salt-cored [[anticline]] in the eastern [[Mississippi]] Interior Salt Basin of southwest Alabama. The [[elliptic dome|dome]] forms an elliptical structural closure containing multiple opportunities for [[enhanced oil recovery]] (EOR) and saline reservoir [[Carbon sequestration|CO2 sequestration]].
