Example answer

“During my tenure at ENI, I managed a complex offshore oil well project that encountered unexpected geological formations. To address this, I led a thorough risk assessment and implemented a new drilling technique that reduced costs by 15% while maintaining safety standards. The project was completed on time, resulting in a 20% increase in production efficiency. This experience reinforced my belief in proactive planning and the importance of teamwork in overcoming technical challenges.”

Introduction

This question is essential for evaluating your technical expertise and problem-solving abilities in oil well engineering, particularly in overcoming real-world challenges.

How to answer

• Use the STAR method (Situation, Task, Action, Result) to structure your response
• Clearly describe the specific well design project and the challenges faced
• Explain the technical solutions you implemented to overcome these challenges
• Highlight any collaboration with cross-functional teams or stakeholders
• Quantify the results in terms of efficiency, cost savings, or production increases

What not to say

• Vague descriptions of the project without specific challenges
