Methods for treating a hydrocarbon containing formation are described
herein. Methods may include treating a first zone of the formation.
Treatment of a plurality of zones of the formation may be begun at
selected times after the treatment of the first zone begins. The
treatment of at least two successively treated zones may begin at a
selected time after treatment of the previous zone begins. At least two
of the successively treated zones may be adjacent to the zone treated
previously. The successive treatment of the zones proceeds in an outward,
substantially spiral sequence from the first zone so that the treatment
of the zones may move substantially spirally outwards towards a boundary
of the treatment area.
