During the process of drilling for hydrocarbons, there is often the need to set a cementitious material plug in an open hole to allow the process of sidetracking and drilling of a new well bore. The present invention provides an apparatus 100 and method for setting a cementitious material plug in an irregularly shaped and/or over gauge well bore without contamination of the cementitious material by extruding a membrane 120 filled with cementitious material from a membrane delivery device 130. |
