Étude comparative des systèmes contenant des gaz acides

Abstract

As the behaviour of mixtures containing acid gases (CO2+ H2S) with hydrocarbons and/or water increases, these needs are now well defined in the field of gas injection to improve hydrocarbons production and comply with environmental constraints. Description of fluid behaviours (injected gas + hydrocarbons inside the well + groundwater) in injection conditions is particularly important for the progress of the process. In addition, the ability of these gases to produce acidic communities in the presence of water can have important implications in identifying the materials used to reduce the problem of corrosion. This research is based on comparing previous studies in this area to come up with a clearer picture of acidic gas behaviours.
