A deployable baffle apparatus installed in a casing to isolate sections of a wellbore during stimulation treatments. The deployable baffle is inserted and positioned within a wellbore by a setting tool. To deploy the deployable baffle, the setting tool expands an expandable section of the deployable baffle such that the outer wall of the expandable section contacts an inner surface of the casing. Once the deployable baffle is deployed, the deployable baffle is detached from the setting tool and the tool sting may be repositioned for other downhole operations or removed from the wellbore. The deployable baffle includes an inner baffle for receiving an untethered object such that a seal is formed between the inner baffle and the untethered object, permitting isolation of adjacent wellbore sections. Any or all of the deployable baffle and the untethered object may be made of a dissolvable material. |
