Abstract:
A wiper plug can be used in wellbore operations. The wiper plug can include a fishing neck located at a rear portion of the plug. The fishing neck can be a male or female fishing neck. A corresponding male or female fishing tool can be used to retrieve the wiper plug from a tubing string. The wiper plug can include a nose that can land on a landing tool or a female fishing neck of another wiper plug. The wiper plug can be introduced into the tubing string before or after a cement composition. The wiper plug can include a rupture disk that allows an operator at a wellhead to observe a pressure change to indicate the location of the wiper plug and fluid within the tubing string.
