Working Interest in current zone vs. future zone

I have working interest in a well that is non profitable to produce in its current zone. The well was drilled in 2005 and the logs show a very good zone upper from the zone that is currently being produced. Can i go non consent on the current zone that is being operated and then when the upper zone is re-completed be back in on the well? If so, what if anything will i owe the operator? Thanks in advance
