L'injection de gaz joue un rôle crucial dans le maintien et l'amélioration de la production de pétrole et de gaz. Elle consiste en l'introduction contrôlée de gaz dans un réservoir ou un puits, servant à diverses fins liées à la gestion de la pression du réservoir et à l'optimisation du puits. Voici une analyse des deux principales applications du gaz injecté:
1. Maintien de la Pression du Réservoir:
2. Opérations de Gaz Lift:
Considérations Essentielles:
Conclusion:
L'injection de gaz joue un rôle crucial dans la maximisation du rendement pétrolier et gazier en maintenant la pression du réservoir et en améliorant les performances du puits. Comprendre les différents types de gaz injectés et leurs applications est essentiel pour une production efficace et une optimisation des réserves de pétrole et de gaz.
Instructions: Choose the best answer for each question.

d) Carbon dioxide.
3. How does injection gas contribute to reservoir pressure maintenance?
a) By removing dissolved gases from the reservoir. b) By creating a vacuum in the reservoir. c) By acting as a pressure support system, expanding pore space and pushing fluids towards the well. d) By reducing the density of the reservoir fluids.
c) By acting as a pressure support system, expanding pore space and pushing fluids towards the well.
4. What is the main benefit of gas lift operations?
a) To increase the viscosity of produced fluids. b) To enhance flow rates and improve well performance, particularly in wells with high water production or high-viscosity fluids. c) To decrease the temperature of the reservoir. d) To prevent the formation of gas hydrates.
b) To enhance flow rates and improve well performance, particularly in wells with high water production or high-viscosity fluids.
5. What is a critical consideration when choosing injection gas?
a) The color of the gas. b) The odor of the gas. c) The chemical composition and purity of the gas. d) The availability of the gas at a low price.
c) The chemical composition and purity of the gas.
Scenario: An oil well is experiencing declining production due to falling reservoir pressure. To address this, the operators are considering injecting gas into the reservoir to maintain pressure and enhance production.
