	A system for treating a hydrocarbon containing formation is described. The system includes two or more groups of elongated heaters. The group includes two or more heaters placed in two or more openings in the formation. The heaters in the group are electrically coupled below the surface of the formation. The openings include at least partially uncased wellbores in a hydrocarbon layer of the formation. The groups are electrically configured such that current flow through the formation between at least two groups is inhibited. The heaters are configured to provide heat to the formation. Grouped exposed metal heaters	Vinegar, Harold J. , Coit, William George , Griffin, Peter Terry , Hamilton, Paul Taylor , Hsu, Chia-Fu , Mason, Stanley Leroy , Samuel, Allan James , Watkins, Ronnie Wade	11/09/2010	7,831,134
