Abstract:
The present invention is related to a downhole tool having a flapper valve assembly for controlling the backflow of fluid into a tubing string. The downhole tool includes a first sleeve slidably disposable within at least a portion of the flapper valve assembly and the downhole tool. The downhole tool can also include a second sleeve slidably disposed within the downhole tool. The present invention is also related to a method of using the downhole tool. The method includes the step of positioning the downhole tool in a wellbore. Once the downhole tool is positioned in the wellbore, the first sleeve is shifted to interact with the flapper valve assembly.
