Thermodynamic experimental study of an Algerian condensate gas

Abstract

When a gas field is discovered, the gas condensate is often in a gaseous single-phase state in the reservoir under pressures and at temperatures which are higher the greater the depth. During operation, the pressure drop in the repository results in liquid deposits in both the repository and surface facilities. These liquid deposits are composed for the most part of heavy constituents of great importance for the producer. They are usually unrecoverable. For this, we carry out a thermodynamic study, called the PVT study, the object of our current work concerning the condensate gas coming from a newly discovered deposit in southern Algeria. A series of experiments was carried out, making it possible to experimentally determine physical-chemical and thermodynamic properties. A GPC analysis was then performed to determine the gas condensate composition under study.
