Non-Producing Reserves

Libérer le potentiel : Comprendre les réserves non productrices dans le secteur pétrolier et gazier

Dans l'industrie pétrolière et gazière, les « réserves » représentent le volume estimé d'hydrocarbures qui peuvent être extraits économiquement d'un champ donné. Alors que la plupart des discussions se concentrent sur les **réserves productrices**, qui sont actuellement extraites, il existe une catégorie importante de **réserves non productrices**. Ces réserves, bien que techniquement récupérables, ne produisent pas actuellement en raison de divers facteurs.

Les **réserves non productrices** sont subdivisées en **réserves fermées** et en **réserves en aval des pipelines**. Examinons plus en détail chaque catégorie :

**Réserves fermées :**

Ces réserves représentent les hydrocarbures qui devraient être récupérés de :

  • **Intervalles de complétion :** Il s'agit de sections d'un puits qui ont été préparées pour la production mais qui n'ont pas encore commencé à produire. Cela peut être dû à des facteurs tels que l'attente de conditions de production optimales ou l'attente du développement des infrastructures.
  • **Puits fermés :** Ces puits ont été temporairement fermés en raison des conditions du marché (par exemple, les prix bas du pétrole) ou de problèmes de connectivité des pipelines. Une fois que les conditions du marché s'améliorent ou que les infrastructures sont en place, ces puits peuvent être réactivés.
  • **Puits avec des problèmes mécaniques :** Ces puits ne produisent pas en raison de difficultés techniques telles que des pannes d'équipement ou des dommages au puits. Une fois les problèmes mécaniques résolus, la production peut reprendre.

**Réserves en aval des pipelines :**

Ces réserves sont situées dans des zones adjacentes aux puits existants, nécessitant potentiellement des forages supplémentaires ou des techniques de récupération améliorées. Leur récupération peut être différée pour diverses raisons, notamment :

  • **Viabilité économique :** Le coût d'extraction de ces réserves peut ne pas être économiquement viable dans les conditions actuelles du marché.
  • **Défis techniques :** Les puits existants peuvent ne pas être idéalement positionnés pour accéder à ces réserves, nécessitant de nouveaux forages ou des méthodes d'extraction sophistiquées.
  • **Préoccupations environnementales :** L'extraction des réserves en aval des pipelines pourrait soulever des préoccupations environnementales, nécessitant des investigations et des stratégies d'atténuation supplémentaires.

**Comprendre l'importance des réserves non productrices :**

  • **Potentiel futur :** Les réserves non productrices représentent un potentiel important pour la production future, augmentant la récupération globale d'un champ.
  • **Planification des ressources :** La reconnaissance et la quantification des réserves non productrices sont cruciales pour une planification précise des ressources et des décisions d'investissement.
  • **Développement stratégique :** Comprendre les raisons de la non-production permet de développer des stratégies pour libérer ce potentiel, telles que les avancées technologiques, la surveillance des conditions du marché et le développement des infrastructures.

**En conclusion :**

Les réserves non productrices sont un aspect crucial de l'évaluation des ressources pétrolières et gazières. En comprenant les divers facteurs qui contribuent à leur état de non-production, les entreprises peuvent mettre en œuvre des stratégies pour libérer leur potentiel, augmentant la récupération globale des ressources et contribuant à la viabilité économique à long terme. Cette approche complète garantit qu'aucune pierre n'est laissée de côté pour maximiser la valeur des ressources en hydrocarbures.

Exercise: Unlocking the Potential:

Scenario:

An oil and gas company has a large field with existing producing wells. They have identified a significant amount of behind-pipe reserves that are not being exploited. These reserves are estimated to hold a substantial amount of hydrocarbons but are currently not economical to extract due to the high cost of drilling and the need for enhanced recovery techniques.

Task:

Based on the information provided, develop a list of potential strategies that the oil and gas company could implement to unlock the potential of these behind-pipe reserves. Consider the following factors:

  • Economic Feasibility: Evaluate the current market conditions and potential future trends in oil prices.
  • Technological Advancements: Research and identify emerging technologies in enhanced oil recovery that could make the extraction of these reserves more economically viable.
  • Environmental Impact: Consider any potential environmental concerns associated with exploiting these reserves and explore mitigation strategies.

Instructions:

  • Provide a concise and comprehensive list of strategies.
  • Justify each strategy by explaining how it addresses the factors mentioned above.

Exercice Correction

Here are some potential strategies the oil and gas company could implement:

  • **Monitor Market Conditions and Future Oil Prices:** Continuously track oil prices and anticipate potential price increases. When prices rise sufficiently, the company can re-evaluate the economic feasibility of exploiting the behind-pipe reserves.
  • **Invest in Research and Development of Enhanced Oil Recovery Technologies:** Focus on innovative technologies that reduce the cost of drilling and enhance the recovery rate of hydrocarbons. This could include advancements in horizontal drilling, fracking, or carbon dioxide injection techniques.
  • **Develop a Comprehensive Environmental Impact Assessment:** Conduct a thorough assessment to identify potential environmental risks associated with extracting these reserves. This could include risks to water resources, air quality, and biodiversity. Implement mitigation strategies to minimize these risks and comply with environmental regulations.
  • **Seek Government Incentives and Subsidies:** Explore potential government incentives or subsidies available for oil and gas companies involved in enhanced recovery projects or utilizing environmentally friendly extraction methods.
  • **Collaborate with Research Institutions and Technology Providers:** Partner with universities or research institutions to develop and test cutting-edge technologies that can enhance the extraction process and reduce environmental impact.

These strategies aim to balance economic feasibility, technological advancements, and environmental responsibility in unlocking the potential of behind-pipe reserves.
