Abstract
An apparatus and method are disclosed for wet shoe applications in cementing tubing in a wellbore. A wet shoe tool has a seat and an insert in a flow bore of the tool. A first wiper plug is deployed down the tubing at least behind the cement and seats on the insert, which can then be moved in the flow bore to a bypass position allowing for fluid flow through the tool to produce a wet shoe track. A second plug is deployed down the tubing behind the second plug and seats on the seat in the flow bore of the tool. The seated second plug isolates applied pressure from passing downhole end of the tool so the integrity of the tubing can be tested. The second plug is self-removable (e.g., dissolvable) in the tool to reestablish fluid communication through the flow bore of the tool.
