Le monde des projets pétroliers et gaziers est complexe, dynamique et souvent confronté à des défis imprévus. Si une planification minutieuse est essentielle, des circonstances imprévues, telles que des retards météorologiques, des pannes d'équipement ou des modifications réglementaires, font souvent dérailler le calendrier initial. C'est là que le "Planning du Réel" devient un outil puissant, offrant une image claire de la façon dont le projet s'est réellement déroulé.
Qu'est-ce qu'un Planning du Réel ?
Un Planning du Réel est une reconstruction du calendrier du projet qui reflète fidèlement la séquence et les durées des tâches telles qu'elles ont été effectivement réalisées. Il sert de registre historique de l'exécution du projet, capturant les écarts par rapport au plan initial.

Scenario: You are a project manager reviewing the As-Built Schedule for an oil well drilling project. You notice the following:
Task:
1. **Type of Delay:** Excusable Delay. 2. **Explanation:** The delay was caused by a faulty drilling bit, which is considered an unforeseen equipment failure. This is beyond the contractor's control, making it an excusable delay. 3. **Mitigation Action:** Implementing a rigorous equipment inspection and maintenance program before drilling operations can help identify potential issues with drilling bits and prevent future delays.
This document expands on the concept of As-Built Schedules in the context of Oil & Gas projects, broken down into distinct chapters.
Chapter 1: Techniques for As-Built Schedule Creation
Creating a robust As-Built Schedule requires a systematic approach encompassing several key techniques:
Data Collection: This is the foundational step, requiring diligent gathering of information from diverse sources. This includes:
Data Verification and Validation: Raw data needs careful scrutiny. Cross-referencing data from multiple sources is essential to ensure accuracy and identify discrepancies. This step helps prevent errors from propagating through the As-Built Schedule.
Schedule Updating Methodologies: Several methods exist for updating the original schedule to reflect actual progress:
Critical Path Method (CPM) Update: Applying the CPM algorithm to the updated task durations and sequencing to identify the new critical path and potential bottlenecks. This is essential for understanding the project's overall completion timeline.
Delay Analysis Techniques: Employing established methods such as:
Chapter 2: Models for Representing As-Built Schedules
Various models can be used to represent the As-Built Schedule effectively:
Bar Charts (Gantt Charts): A visual representation of tasks against a timeline, effectively showing task durations, dependencies, and actual vs. planned progress. While simple, they can become complex for large projects.
Network Diagrams (Precedence Diagramming Method - PDM): Illustrate task dependencies graphically, providing a clearer understanding of the project's critical path. More suitable for complex projects.
Spreadsheet Software: Spreadsheets can capture task information, durations, and actual completion dates. They offer flexibility but lack the visual clarity of graphical models.
Project Management Software: Dedicated project management software (discussed further in Chapter 3) provides advanced features for creating and managing As-Built Schedules, including automated updates and delay analysis tools.
The choice of model depends on the project's complexity, team familiarity, and available resources. Often a hybrid approach, combining different models, proves most effective.
Chapter 3: Software for As-Built Schedule Management
Several software solutions aid in As-Built Schedule creation and analysis:
Primavera P6: A powerful industry-standard project management software offering advanced scheduling capabilities, including robust delay analysis tools.
Microsoft Project: A widely used tool offering basic scheduling functionalities suitable for smaller projects.
Other Project Management Software: Various other software options exist, each with its strengths and weaknesses. Selection should consider project scale, budget, and specific requirements.
Regardless of the software selected, data integrity and consistent updating are paramount for accurate As-Built Schedule generation.
Chapter 4: Best Practices for As-Built Schedule Development
Several best practices enhance the effectiveness of As-Built Schedule creation:
Proactive Data Management: Establish a structured system for collecting and storing project data throughout the project lifecycle.
Regular Data Updates: Ensure consistent and timely updates to maintain the accuracy of the As-Built Schedule.
Clear Communication: Foster effective communication between project teams to facilitate accurate data collection and reporting.
Independent Verification: Having an independent party review the As-Built Schedule helps ensure accuracy and objectivity.
Documentation: Thoroughly document all changes, delays, and their justifications.
Version Control: Maintain version control to track changes and revert to previous versions if needed.
Chapter 5: Case Studies of As-Built Schedule Applications in Oil & Gas
(This chapter would include specific examples of how As-Built Schedules were used in actual Oil & Gas projects. Each case study should detail the project, the challenges encountered, how the As-Built Schedule was used to analyze the project's performance, and the lessons learned.)
For example, a case study might focus on:
These case studies would illustrate the practical application of As-Built Schedules and demonstrate their value in managing risk, improving future project planning, and resolving disputes in the oil and gas sector.
