ABSTRACT
A method to convert multiple shot section open hole completions into cased hole completions has been developed and tested. This method provides zonal isolation between shot sections thus helping prevent injection fluid loss to non-pay intervals. The process, called "Puddle-Pack", involves formulating a permeable resin fill material and placing the material in the shot open hole to fill the large voids. The excess material is then drilled out and underreamed to allow a liner to be run and cemented in place. This paper details the necessity for the development of the process, design requirements, laboratory pretesting of the sand-resin mixture, remedial procedures, data demonstrating zonal isolation and profile improvement, and economic advantages of converting these wells to cased hole completions.
