Prévention et inhibition des dépôts de sulfate dans les installations pétrolières. Une application sur un champ saharien
Institut Français du Pétrole
Among the main problems raised by water injection in oilfields, the physiocochemical opposition prevailing between injected water and field water is certainly still the one which is the worst masterd at explitation level. The deposits and the corrosions produced or encouraged by the various precipitation reactions generate degradations which are often irreversible and particularly noxious for the reservoir rock and for the deep production equipments as for the surface ones.
Within the framework of research and development work, carried out at the French Petroleum Institute, related to injection and productivity of wells, this article presents the convincing results of a test carried out in full injection-size with a inhibitor of barium sulfate deposits, specifically adapted to the hard production conditions of a field in South Algeria.
