Abstract:
1. A method of providing a temporary flow barrier in a wellbore, the method comprising: providing a wellbore element including a body having two or more tapered fins extending therefrom, wherein the body, the fins, or both are made from at least one reactive metal in major proportion and at least one alloying element in minor proportion selected from the group consisting of aluminum, zinc, magnesium and combinations thereof, wherein a coating is disposed about the body, the fins, or both, and, wherein the coating includes aluminum; depositing the wellbore element into a tubing string so that the wellbore element engages and cooperates with a seat to block fluid flow therepast; pumping stimulation fluid into the tubing string to stimulate an area of the wellbore above the seat, the wellbore element having structural integrity to withstand the fluid pressure; and degrading the wellbore element so that the wellbore element and seat allow for the flow of fluid past the seat.
