Dans l'industrie pétrolière et gazière, le condensat fait référence à un type spécifique de liquide hydrocarboné qui se présente initialement sous forme de vapeur dans les formations souterraines. C'est un composant précieux de la production de gaz naturel, souvent appelé "or liquide" en raison de sa haute qualité et de son potentiel commercial.
**La formation du condensat :**
Imaginez un réservoir de gaz naturel situé profondément sous terre. Ce réservoir est rempli d'un mélange de gaz, notamment du méthane, de l'éthane, du propane, du butane et d'hydrocarbures plus lourds. Lorsque ce mélange remonte vers la surface dans le puits, il est soumis à une baisse de pression et de température. Ce changement de conditions provoque la condensation de certains des hydrocarbures les plus lourds (ceux ayant un poids moléculaire plus élevé) de leur état gazeux à l'état liquide. Ce liquide est ce que l'on appelle le condensat.
