20110030947 | Stimulating subterranean zones - The present disclosure is directed to a system and method for stimulating subterranean zones. In some implementations, a method for stimulating a subterranean zone includes pumping stimulation fluid through a tubing string in a wellbore during a stimulation process. The tubing string includes a plurality of sleeves with each associated with a different treatment zone of the subterranean zone. A time for each of a plurality of different sealers entering the tubing string is detected. Each of the plurality of different sealers is associated with a different one of the plurality of sleeves. A location of the plurality of different sealers in the tubing string is substantially determined based, at least in part, on the associated entry time. | 02-10-2011 |
