Decommission operations, in the hydrocarbons sector, are essential to maintain a clean environment. We propose a guideliness to provide a methodology to standardize the decommission procedures establishing a logical structure in the operations. It shows the generation of possible decommission alternatives. They are picked up in three types, abandonment that is to leave the infrastructure in the place, dismantlement that is the total dismounts of the pieces that compose it, reutilization that will be the new use that will be given to the things. Finally, through an appropriate environmental management, to select the best decommission alternatives that mitigate the impacts and the generation of environmental passives. A project can be presented the abandonment, the reutilization and the dismantlement simultaneously. Also, there are a form to organize and to evaluate the process of decommission. The interdisciplinary work has great importance in this process, as well as an appropriate social management with the affected communities.
