ABSTRACT:
An improved seal element especially for well packers having multiple mandrels, the improvement providing slits therein of various configurations which allow the seal element to be expanded to sealing condition in response to longitudinal compression such that the resultant stresses created within the element body are minimized in that they are substantially evenly distributed therethrough, thus enabling the multiple packer to seal more readily and to withstand greater pressure differentials.
