Optimizing oil production consists of maintaining if not improving recovery by taking into account the reservoir parameters. Several methods are used to optimize production. Among these methods are: well activation, completion, additional perforations, stimulation, chemical injection and many others. In this book, the objective is to improve the production of the LAF1-24 well, using one of the above mentioned methods. To achieve this objective, a data acquisition system was used. This system consisted in investigating the well: its history, the well tests in order to determine the exact cause of this drop in production. The results of these investigations allowed us to adopt the stimulation by acidification of the formation matrix as a process to optimize the production of the LAF1-24 well. However, it should be noted that the chosen option still does not bring the expected result. Thus, the result obtained at the end of this operation is not satisfactory compared to the expectations formulated.
