Permanent-Type Well Completion

Abstract

Very encouraging progress has been made in the development of the permanent-type well completion which decreases considerably the cost of completions and workovers and aid, in the acquisition of reliable reservoir information at low cost. Completion and remedial operations are performed with tools which pass through the well tubing. Perforating and plug-back operations can be done with the tubing in place and do not require pipe-handling equipment. Because of the many advantages afforded by this method, development work is going forward in anticipation of ultimately being able to use it to perform all usual well completion and workover operations. Effort is also being directed to the development of a more permanent type of lift equipment suitable for use with the permanent-type well completion.
