Dans le monde de la production pétrolière et gazière, maximiser le volume des fluides extraits est une quête constante. Cependant, le trajet du réservoir à l'usine de traitement n'est pas toujours fluide. En cours de route, certains composants peuvent être retirés, ce qui entraîne une diminution du volume global - un phénomène connu sous le nom de **perte d'extraction**.
**Qu'est-ce qu'une perte d'extraction ?**
La perte d'extraction fait référence à la **perte de volume** subie par les fluides produits pendant le traitement. Cette perte résulte de la **suppression de composants spécifiques**, tels que les gaz ou les liquides, qui sont soit :
**Composants clés contribuant à la perte d'extraction :**
**Impact de la perte d'extraction :**
**Mesure et minimisation des pertes d'extraction :**
**Conclusion :**
La perte d'extraction est un facteur essentiel dans la production pétrolière et gazière, affectant les revenus, l'optimisation de la production et la gestion du réservoir. En comprenant les causes, l'impact et la mesure de la perte d'extraction, les professionnels du secteur peuvent prendre des décisions éclairées pour minimiser cette perte et optimiser la rentabilité de leurs opérations.

Scenario: A well produces 100 barrels of oil per day. The oil contains 5% dissolved gas by volume. During processing, 90% of the dissolved gas is liberated.
Task: Calculate the daily volume of oil lost due to dissolved gas liberation.
Here's how to calculate the daily volume of oil lost:
Therefore, the daily volume of oil lost due to dissolved gas liberation is 4.5 barrels.
