Dans le monde du pétrole et du gaz, où les projets sont complexes, les délais serrés et les défis imprévus fréquents, une gestion de projet précise est cruciale. Le « Calendrier Exécuté » est un outil clé dans ce processus, offrant une image claire et détaillée de l'exécution réelle du projet.
Qu'est-ce qu'un Calendrier Exécuté ?
Le Calendrier Exécuté, souvent appelé « Calendrier Réel », documente la progression réelle d'un projet pétrolier et gazier. Contrairement au calendrier initial planifié, qui décrit des délais et des durées idéaux, le Calendrier Exécuté reflète les dates de début réelles, les dates de fin réelles et les durées réelles de chaque tâche et activité.
Pourquoi le Calendrier Exécuté est-il important ?
Comprendre le Calendrier Exécuté est essentiel pour plusieurs raisons :

Scenario:
You are reviewing an As-Performed Schedule for an oil and gas drilling project. The initial planned schedule estimated a total project duration of 100 days. The As-Performed Schedule reveals the following:
Task:
1. **Actual Project Duration:** * Planned duration: 100 days * Delay due to late start: +15 days * Delay due to late completion: +25 days * Delay due to change orders: +10 days * Delay due to equipment malfunction: +5 days * Delay due to weather conditions: +10 days * **Total Actual Duration: 100 + 15 + 25 + 10 + 5 + 10 = 165 days** 2. **Key Factors Contributing to Delay:** * **Late Start:** This indicates potential issues with project initiation and resource availability. * **Late Completion:** This suggests challenges in project execution and overcoming unforeseen circumstances. * **Change Orders:** This highlights the importance of thorough site assessment and risk mitigation for potential geological challenges. * **Delays due to Equipment Malfunction and Weather Conditions:** This underscores the need for robust contingency plans and equipment maintenance protocols. 3. **Potential Improvements for Future Projects:** * **Improved Project Planning:** More detailed planning, including buffer time for potential delays, to account for realistic timelines. * **Enhanced Site Assessment:** Thorough geological investigations to identify and mitigate potential challenges. * **Equipment Maintenance:** Regular maintenance and backup equipment to minimize equipment-related delays. * **Weather Contingency Plans:** Developing contingency plans for weather-related delays, such as utilizing specific work windows or having alternative options for key activities. * **Effective Communication and Coordination:** Clear communication channels between project teams and stakeholders to address delays promptly.

This chapter discusses different models and approaches for creating As-Performed Schedules, considering the specific needs of oil and gas projects.
2.1. Traditional Gantt Chart Model: A simple, visual representation of project tasks, dependencies, and timelines. It is effective for smaller projects but may require additional layers of detail for complex oil and gas projects.
2.2. Network Diagram Model: Uses a network of nodes and arrows to depict project tasks and their relationships, allowing for more comprehensive visualization of dependencies and critical paths. This model is particularly suited for complex oil and gas projects with intricate workflows.
2.3. Critical Path Method (CPM): Analyzes the dependencies between tasks and identifies the longest sequence, known as the critical path. This helps to prioritize tasks and monitor their progress for timely project completion.
2.4. Earned Value Management (EVM): A comprehensive approach to project management that tracks the value of completed work against the planned budget and schedule. EVM provides a quantitative measure of project performance and allows for proactive identification of potential issues.
2.5. Hybrid Models: Combining elements from various models, such as Gantt charts, network diagrams, and EVM, can provide a tailored approach for specific project needs.
