Our Client
A $30+ billion upstream oil and gas company operating across mining, upgrading, refining, and maintenance activities.
The Challenge
The company sought to enhance its Continuous Improvement program to achieve significant cost savings and performance gains across upstream operations.
- Capacity constraints in critical process areas (loaders, boilers, load/off-load racks) due to chronic downtime.
- Low maintenance productivity, with wrench time at only 40%.
- High contractor dependency, with 70% of internal staff replaced or supported by embedded contractors.
- Lack of standardized performance management, leading to inconsistent leadership execution and accountability.
Real Results Achieved Together
Through Kaizen and Lean methodology deployment, EFESO enabled measurable improvements in productivity, reliability, and cost efficiency while embedding a sustainable Continuous Improvement culture.
