Abstract
A baffle system for use in well casing having a plurality of landed subs therein, for progressive injection of a fracking or treating fluid into a hydrocarbon formation via existing or created perforations in the well casing. The baffle members provide a plug seat, and are each frangibly affixed to a conveying tool and have collet finger protuberances thereon. The collet finger protuberances of each baffle are of a different width, and respectively engage only one annular recess of a corresponding width in a respective landing sub. Each annular recess and/or collet finger protuberance on an uphole edge thereof has a chamfer which allows disengagement of the collet finger protuberances and thus removal of the baffle member from the well casing upon upward force being applied to the baffle member. A method of using the baffle system is also disclosed.
