Abstract
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.
Claims20
A method, comprising:
- pumping stimulation fluid through a tubing string in a wellbore during a stimulation process, the tubing string including a plurality of sleeves with each associated with a different treatment zone of the subterranean zone;
- detecting a time for each of a plurality of different sealers entering the tubing string, each of the plurality of different sealers associated with a different one of the plurality of sleeves;
- and
- substantially determining a location of the plurality of different sealers in the tubing string based, at least in part, on the associated entry time.
A method, comprising:
- selectively positioning a sensor at least proximate an opening of a tubing string in a wellbore in connection with a stimulation process, the tubing string including a plurality of sleeves with each associated with a different treatment zone of the subterranean zone;
- detecting a time an initial sealer enters the opening of tubing string using the sensor;
- and
- substantially determining a location of the initial sealer in the tubing string based, at least in part, on the entry time.
A system, comprising:
- a wellbore configured to pump stimulation fluid through a tubing string during a stimulation process, the tubing string including a plurality of sleeves with each associated with a different treatment zone of the subterranean zone;
- a sensor configured to detect a time for each of a plurality of different sealers entering the tubing string, each of the plurality of different sealers associated with a different one of the plurality of sleeves;
- and
- a stimulation system configured to substantially determine a location of the plurality of different sealers in the tubing string based, at least in part, on the associated entry time.
