Dans le monde dynamique et complexe des projets pétroliers et gaziers, une gestion de projet précise est cruciale pour le succès. Si le suivi de l'avancement repose souvent sur le pourcentage d'achèvement, une métrique plus éclairante est l'effort restant. Cette métrique, plutôt que de se concentrer sur la quantité de travail effectuée, met l'accent sur l'effort encore nécessaire pour atteindre l'achèvement.
L'effort restant : un regard plus approfondi
L'effort restant est la quantité estimée de travail, mesurée en temps, en ressources ou en d'autres unités pertinentes, qui reste à réaliser. Cela fournit une vue plus granulaire et plus opérationnelle de l'avancement du projet par rapport au pourcentage d'achèvement.
Pourquoi l'effort restant est important
Visibilité en temps réel : Contrairement au pourcentage d'achèvement, qui peut être subjectif et trompeur, l'effort restant offre une image plus claire de l'avancement réel. Il permet d'identifier les obstacles et les retards potentiels dès le début, permettant des ajustements proactifs.
Allocation des ressources : En comprenant l'effort restant, les chefs de projet peuvent optimiser l'allocation des ressources et s'assurer que les bonnes ressources sont disponibles au bon moment. Cela minimise les retards et maximise l'efficacité.
Prévisions précises : L'effort restant permet des prévisions plus précises des délais et des budgets du projet. En tenant compte de l'effort restant et des risques potentiels, les équipes de projet peuvent prendre des décisions plus éclairées concernant la portée du projet et les livrables.

Défis et meilleures pratiques
Conclusion
L'effort restant offre une perspective plus nuancée et plus opérationnelle sur l'avancement du projet que le pourcentage d'achèvement. En adoptant cette métrique, les entreprises pétrolières et gazières peuvent améliorer la gestion de projet, optimiser l'allocation des ressources et garantir l'achèvement rapide et efficace des projets critiques. Le passage du pourcentage d'achèvement à l'effort restant représente un passage à une approche de gestion de projet plus axée sur les données et plus proactive dans l'industrie dynamique du pétrole et du gaz.

Scenario: You are the project manager for a pipeline construction project. The initial project plan estimated 120 days of work for laying 50 kilometers of pipeline. After 60 days, 25 kilometers have been completed.
Task:
1. Calculation of Effort Remaining: * Initial estimation: 120 days for 50 km * Work completed: 25 km in 60 days * Remaining work: 25 km * Assuming a linear relationship between work and time: * Effort Remaining = (25 km / 50 km) * 120 days = 60 days. 2. Estimated Remaining Days: * Work completed: 25 km in 60 days * Remaining work: 25 km * Based on current progress, it will take another 60 days (same as already spent) to complete the remaining 25 km. * Therefore, total estimated project duration = 60 days (already spent) + 60 days (estimated remaining) = 120 days. 3. Challenges and Adjustments: * Potential delays due to unforeseen circumstances like bad weather, equipment failure, or permitting issues. * Change in project scope or specifications might require additional work and extend the timeline. * Increased efficiency or optimized work practices could potentially reduce the remaining time. Adjustments to the Estimation: * Factor in contingency time for potential delays. * Monitor progress closely and adjust estimations based on actual performance. * Communicate any changes to the project scope or timelines to stakeholders.
Chapter 1: Techniques for Estimating Effort Remaining
Accurate estimation of effort remaining is crucial for its effective use. Several techniques can be employed, each with its strengths and weaknesses:
Analogous Estimating: This technique leverages historical data from similar projects to estimate the effort required for the current project. It's quick but relies on the similarity of past and present projects. In Oil & Gas, this might involve comparing the drilling time of a similar well in a similar geological formation.
Bottom-up Estimating: This method involves breaking down the project into smaller, more manageable tasks and estimating the effort for each. The individual estimates are then summed to get the total effort. It's more precise than analogous estimating but requires significant detail and expertise. For pipeline construction, this might involve estimating welding time per pipe segment, plus time for inspections and material handling.
Three-Point Estimating: This technique incorporates uncertainty by using three estimates: optimistic, pessimistic, and most likely. A weighted average is then calculated to obtain a more realistic estimate. In facility commissioning, this could involve estimating the time for testing various systems, considering best-case, worst-case, and most likely scenarios.
Expert Judgment: This involves soliciting estimates from experienced professionals in the relevant field. This is particularly valuable for unique or complex tasks where historical data is limited. For deepwater drilling operations, relying on the judgment of experienced drilling engineers is essential for accurate effort estimation.
Agile Estimation Techniques: Methods like Story Points or T-Shirt sizing can be useful for estimating effort in iterative projects. These are less focused on precise time estimates and more on relative effort, allowing for flexibility as the project progresses.
Chapter 2: Models for Tracking Effort Remaining
Effective tracking requires appropriate models:
Work Breakdown Structure (WBS): Breaking down the project into smaller, manageable tasks allows for more accurate tracking of effort at the task level. Progress against each task can then be aggregated to provide an overall view of effort remaining.
Earned Value Management (EVM): This comprehensive project management system integrates scope, schedule, and cost to provide a holistic view of project performance. EVM can be used to calculate the schedule variance and cost variance, helping to estimate effort remaining more accurately.
Agile Project Management Frameworks (Scrum, Kanban): These iterative frameworks emphasize continuous tracking and adaptation. Using tools like burndown charts, effort remaining is visually tracked and updated frequently, providing a dynamic picture of project progress.
Monte Carlo Simulation: This statistical technique can incorporate uncertainty and risk into the effort remaining calculation, providing a range of possible outcomes rather than a single point estimate. This is particularly useful for projects with significant uncertainty, such as exploration drilling.
Chapter 3: Software Tools for Managing Effort Remaining
Several software tools can assist in managing effort remaining:
Project Management Software (MS Project, Primavera P6, Asana, Jira): These tools offer features for task management, scheduling, resource allocation, and progress tracking, facilitating the calculation and monitoring of effort remaining.
Earned Value Management Software: Specialized software packages are available for implementing EVM, providing detailed analysis and reporting capabilities.
Agile Project Management Software: Tools supporting Scrum and Kanban provide dashboards and visualizations to track effort remaining and progress within sprints or iterations.
Custom-built applications: For specific needs or integration with existing systems, custom software can be developed to track effort remaining. This might be particularly useful in integrating data from drilling rigs or pipeline monitoring systems.
Chapter 4: Best Practices for Managing Effort Remaining
Effective management of effort remaining requires adhering to several best practices:
Regular Updates: Effort remaining should be updated frequently, ideally on a daily or weekly basis, to reflect the actual progress and any changes to the project scope.
Realistic Estimation: Initial estimations should be realistic and based on sound judgment and historical data. Overly optimistic estimates can lead to inaccurate forecasting and missed deadlines.
Contingency Planning: A buffer should be included to account for unforeseen circumstances and potential delays. This contingency should be explicitly tracked as part of the effort remaining.
Clear Communication: Open communication among team members is essential for accurate tracking and adjustment of effort remaining. Regular status meetings and progress reports are crucial.
Risk Management: Identifying and mitigating potential risks is essential for maintaining accuracy in effort remaining estimates.
Chapter 5: Case Studies of Effort Remaining in Oil & Gas Projects
(This chapter would include specific examples of how effort remaining was used in different Oil & Gas projects. Each case study would detail the specific techniques, models, and software used, along with the results and lessons learned. Examples could include a case study of improved well drilling efficiency through accurate effort remaining tracking, or a case study showcasing reduced project overruns through proactive adjustments based on effort remaining monitoring in pipeline construction.) For instance:
Case Study 1: Optimized Drilling Operations using Bottom-up Estimating and EVM: This case study could demonstrate how a drilling company used bottom-up estimating techniques to break down well drilling into smaller tasks and then employed EVM to track progress, resulting in improved schedule adherence and reduced cost overruns.
Case Study 2: Reduced Pipeline Construction Delays through Agile Tracking of Effort Remaining: This study could illustrate how an agile approach, combined with Kanban boards and daily stand-ups, allowed a pipeline construction team to proactively identify and address potential delays, ultimately completing the project ahead of schedule.
Case Study 3: Improved Facility Commissioning Efficiency with Three-Point Estimating and Monte Carlo Simulation: This study might highlight how a commissioning team utilized three-point estimation and Monte Carlo simulation to account for uncertainty, leading to more realistic scheduling and resource allocation, and minimizing commissioning delays.
