Modélisation intégrée et optimisation du développement du Champ de RAA. Application de

Abstract

Since it went into production in early July 2016, a decline in RAA field productivity has been observed since October of the same year. Current production is around 67 m3 / h instead of 128 m3 / h which represent the potential of open wells (flow as soon as they come into production). The exploitation of the field has become complicated and subject to various constraints of Flow Insurance (migration of fines, salt, asphalt, Water Conning ...). Several interventions were initiated without being able to restore the potential of the wells. The Integrated Modeling and optimization of the development of the RAA field leads to the creation of new wells in horizontal drains or the resumption in Short Radius of the wells with the installation of tubing on the surface. This choice has several technical and economic advantages that can help the development of the field and is a better action to address the problems of farms. A micro-model installation was designed to demonstrate the improvement of productivity indices by the construction of a horizontal drain
