Abstract
A method for treating a hydrocarbon containing formation is described. The method for treating a hydrocarbon containing formation may include heating a first volume (162) of the formation using a first set of heaters (158). A second volume (164) of the formation may be heated using a second set of heaters (158). The first volume may be spaced apart from the second volume b y a third volume of the formation. The first volume, second volume, and/or thi rd volume may be sized, shaped, and/or located to inhibit deformation of subsurface equipment caused by geomechanical motion of the formation during heating.
