Abstract
The mud causes considerable pollution impacting several sectors, especially the groundwater system and the staff working on Drilling wells so as to mitigate the environmental effects of the sludge on the environment we propose two treatment processes (scenarios 1 and scenario 2) like: thermal desorption, stabilization/solidification off line), these treatments are very privileged and used in the field of treatment of oil muds, in (Hassi-Messaoud) Algeria. We use the "life cycle analysis" to evaluate the environmental impacts of each process (the two scenarios), the environmental impacts of each scenario are compared. Which are performed by the use of models of eco-indicator 99 by software “SIMAPRO7”. This evaluation allowed us to identify and quantify the contributions of emissions on human toxicity, the depletion of resources and the ecosystem quality, which are the main categories of impact in this specific Saharian context. The main substances of the assignment of the environment seem to be the chemicals added to the mud. As regards the comparison of the two treatment scenarios, the thermal desorption could be considered as the best method; it has the lowest impact in the three dominant categories scores, aside from the very large consumption of fossil energy causing from atmospheric emission.
