Traitement matreciel par acidification champ Rahlet-El-Aouda

Abstract

The goals of treatment are removal by acidification of clogging around the well and restore the initial permeability of the layer, but it would be wrong to conclude that the injection of an acid in a sedimentary formation always results in improved production. On the contrary, without injecting an acid previously studied in depth, can cause much more severe damage that can not be removed by very expensive treatments such as hydraulic fracturing. The RAMA field is a new field in the periphery of the HMD field, a remarkable drop in production and reservoir pressure were recorded a few months later and the usual restoration attempts failed (sometimes the situation worsened: RAMA1 ), from which it became clear that all the parameters and characteristics of the wells must be finely analyzed. For this, we focused on our work on well performance. We emphasized the results of mineralogy training and acidification tests to propose the most appropriate intervention plan.
