La Technique d'Évaluation et de Révision Graphique (GERT) est un outil précieux utilisé dans l'industrie pétrolière et gazière pour gérer des projets complexes. Il combine les avantages des techniques d'analyse de réseau, telles que PERT (Program Evaluation and Review Technique) et CPM (Critical Path Method), avec la flexibilité de prendre en compte les incertitudes et les événements probabilistes.

Conclusion :
GERT est un outil puissant pour gérer des projets complexes dans l'industrie pétrolière et gazière. En intégrant des événements probabilistes et une logique conditionnelle, GERT permet aux chefs de projet d'analyser les incertitudes, d'identifier les risques potentiels et de développer des stratégies d'atténuation efficaces. Cela conduit à une prise de décision plus éclairée, une planification de projet améliorée et une probabilité accrue d'atteindre les objectifs du projet.
Instructions: Choose the best answer for each question.
1. What is the primary difference between GERT and traditional project management tools like PERT and CPM?
a) GERT focuses solely on project scheduling. b) GERT accounts for probabilistic events and uncertainties. c) GERT is only suitable for small projects. d) GERT relies on deterministic timelines.
b) GERT accounts for probabilistic events and uncertainties.
2. What feature of GERT allows for the representation of repeated activities based on previous outcomes?
a) Network Diagram b) Conditional Logic c) Simulation d) Looping Activities
d) Looping Activities
3. Which of the following is NOT a benefit of using GERT in Oil & Gas projects?
a) Enhanced risk management. b) Improved decision-making. c) Reduced project costs. d) Increased project success.
c) Reduced project costs. While GERT can help optimize resource allocation and prevent unnecessary costs, it doesn't guarantee a reduction in overall project costs.
4. How does GERT facilitate risk assessment in Oil & Gas projects?
a) By identifying potential risks and their impact. b) By providing a framework for developing mitigation strategies. c) By simulating project scenarios under different conditions. d) All of the above.
d) All of the above.
5. Which Oil & Gas application of GERT helps in evaluating the economic viability of a project?
a) Exploration and Production b) Project Planning and Scheduling c) Capital Budgeting d) Risk Assessment and Management
c) Capital Budgeting
Scenario: An oil company is planning to drill an exploratory well. The project involves several steps, including:
Task:
1. GERT Network Diagram:
(0.7) / Start -- Site Selection -- (0.8) -- Drilling -- (0.9) -- Production -- End \ (0.3) \ --- Site Selection
2. Critical Path and Outcomes:
The critical path is: Site Selection -> Drilling -> Production.
3. Potential Risks and GERT:
GERT helps manage these risks by:
