Oil & Gas, Sustainable Energy

Faced with growing maintenance backlogs and the underperformance of CapEx projects, leaders in the oil, gas and sustainable energy sectors are working with EFESO to improve the reliability of infrastructure and to restore value and profitability.

Achieve High Levels of Reliability from Aging Infrastructure

The oil, gas and sustainable energy sectors face major operational challenges. Aging infrastructure requires constant maintenance to sustain production levels, while capital allocation is increasingly shifting toward energy transition initiatives, creating competing resource demands.

Workforce transitions add to these pressures. Experienced technicians are retiring faster than organizations can capture their knowledge, creating gaps that affect asset reliability. At the same time, capital project performance remains inconsistent, with only about half meeting budget and schedule targets.

Market fluctuations demand flexibility that aging assets struggle to provide. Organizations must reduce contractor costs while still requiring specialized expertise for complex equipment and evolving standards.

This combination of infrastructure constraints, workforce shifts and market pressures calls for systematic transformation. Working alongside operators, we implement integrated approaches to reliability, capability building and project execution that deliver tangible returns and sustain operational integrity.

Real Results Achieved with our Clients

Through proven lean and reliability-driven methodologies, we've helped cut maintenance backlogs by up to 67% and boosted asset reliability (MTBF) by as much as 110% (rotating MTBF increased from 60 months to 125 months) while reducing LPO's and unplanned downtime, and also accelerating capital project schedules.

A Tailored and Pragmatic Approach that Fits your Reality

Transformation happens where day-to-day operations align with long-term ambitions. At EFESO, we help your teams to move from reactive maintenance to predictive reliability, from aging infrastructure to smart capital deployment.

From the control room to field operations, we work side-by-side with you to embed visual management systems, implement reliability playbooks and drive efficiency gains. This hands-on collaboration empowers operators and engineers to build lasting capabilities, turning performance improvement into a daily habit.

Capital Projects – Turning Investment into Advantage

Across the industry, fewer than half of capital projects meet both schedule and cost targets.

Reliability – Building a High-Reliability Culture

Unplanned losses, aging infrastructure and mechanical integrity challenges can bring operations to a halt.

Operations – Enabling High-Performance Teams

With workforce turnover and declining procedural discipline, many operators face growing inconsistency and risk.

Maintenance – Reducing Backlogs, Boosting Productivity

Maintenance teams are stretched. Backlogs are growing while productivity gaps remain wide.

Contractor Management – Raising On-Site Productivity

Contractor performance varies—despite digital tools.

Capital Projects – Turning Investment into Advantage

Across the industry, fewer than half of capital projects meet both schedule and cost targets. At the same time, high-value initiatives keep piling up—waiting for the capacity and control to move forward.

We work with you to make capital delivery a strength, not a risk. By applying Lean Construction principles and MIT’s Dynamic Work Design, EFESO helps accelerate project velocity and reduce contractor inefficiencies.

Key Results:

20–30% Reduction in asset downtime
15–25% SPI/CPI improvement
Up to 33% Reduction in contractor costs

Reliability – Building a High-Reliability Culture

Unplanned losses, aging infrastructure and mechanical integrity challenges can bring operations to a halt. EFESO supports teams in creating a culture of reliability-linking operations and maintenance through frontline practices that prevent losses before they occur.

Key Results:

13–18% Reduction in production loss
33–110% MTBF improvement
20–55% Improvement in preventive vs. corrective ratios

Operations – Enabling High-Performance Teams

With workforce turnover and declining procedural discipline, many operators face growing inconsistency and risk. EFESO helps restore clarity, ownership and frontline focus—embedding discipline, routines and high-reliability principles into daily operations.

Key Results:

More perfect safety and environmental days
8–15% Improvement in energy efficiency
5–10% Production increase

Maintenance – Reducing Backlogs, Boosting Productivity

Maintenance teams are stretched. Backlogs are growing while productivity gaps remain wide. EFESO brings lean-based approaches and frontline coaching to deliver measurable gains in efficiency, reliability and cost control.

Key Results:

15–67% Backlog reduction
Up to 42% Improvement in maintenance efficiency
12–31% Reduction in cost per barrel

Contractor Management – Raising On-Site Productivity

Contractor performance varies—despite digital tools. EFESO works with internal and external teams to improve planning, scheduling and execution. The result: stronger coordination, fewer delays and measurable cost savings.

Key Results:

20–40% Increase in labor productivity
30–40% Backlog reduction
15–30% Reduction in contractor spend
