In this paper the idea of use of swellable packers as alternate tool is introduced. Mainly, focusing of using it as option for the cementation of a well. Swellable packers contain sel a stomers, which swallow a certain type of fluid. There are two main groups of swellable packers: elastomers which tend to swallow water-based fluid and elastomers which tend to swallow oil-based fluid. Swellable packers were created to solve the problem of isolate different zones. Its elastomer element swallow the fluid and allows to fill up the rubber which creates a good seal between the different zones. Now days, swellable packers are used in many different ways such as: well stimulation, includying fracturing (allowing high pressures to be applied to the tool), well completion, cementation jobs, etc. After making the several cases analysis and present the advantages of using this tool, a proposal for the use of swellable packers as a cement’s replace mnethad been introduced. This new option would save money in terms of cost operations, rig’s time and NPTs.
