Energy Efficiency

Efficiency has improved 2.8 percent since 2009

We focus on improving operational and energy efficiency to:

Reduce energy use
Conserve resources
Reduce costs
Extend asset life and value
As a strategy for reducing GHG emissions and intensity

Marathon's five-year goal is to improve energy efficiency 5 percent by 2015. At year-end 2010, Marathon had improved efficiency 2.9 percent.

Our energy efficiency team identifies, implements and maintains a database of sustainable, repeatable improvement projects, and shares information across the enterprise.

Approximately 100 projects implemented in 2010 will result in annualized reductions of 8 trillion British thermal units (Btus). The largest improvement is attributable to our Garyville Major Expansion project, where we invested to improve one of the most efficient refineries in the U.S.

Upstream production operations implement procedural changes and projects that extend asset life and reduce energy use, such as optimizing compressors and installing advanced controls for pumping units to reduce electricity consumption.

Marathon's energy efficiency improvements are achieved through projects that reduce energy consumption, flaring, venting and process losses. Although energy efficiency improvements were made in 2010, total energy consumption increased 6.3 percent during the year, largely due to increased refinery throughput volumes.

Our refineries account for 80 percent of our energy use, even though they are among the most efficient in the U.S. Potential obstacles to improving efficiency in our Downstream operations include lower refinery utilization and new regulations that require installing additional process equipment without increasing refinery throughput. Finding and implementing projects to further improve refinery efficiency will continue to be a barrier.

Upstream's primary challenge to improving efficiency and reducing GHGs is the additional energy required to sustain production in declining oil and gas fields.

Brae Projects Increase Energy Efficiency and Asset Life

Several projects extended the life of and reduced energy use on platforms in our U.K. Brae asset. We modified export compressors to recycle seal gas, reducing flared gas. We improved test separator efficiency when offloading wells and installed new power generation sets using the latest technology. The Brae projects saved a total of 857 billion Btus of energy in 2010 and will contribute approximately 805 billion Btus in energy savings in 2011.
