Oil Spill Prevention and Response

To prevent spills and protect the environment, Marathon Oil designs, operates and maintains our facilities with mechanical safeguards, secondary containment systems and spill control plans. We invest in employee training, procedures, preventive maintenance and inspections for fluid-containing equipment and facilities.

 

If a spill does occur, we activate our comprehensive preparedness and response capabilities to contain the spill and protect the surrounding environment. We train local, regional and corporate response teams, and conduct drills and exercises to maintain their readiness. We also have a network of response contractors and consultants.

When investigating spills and discharges to identify their cause, we look at both the actual and potential spill severity. The Company takes incident-specific actions and, if necessary, broad corrective actions including remediation. 

Across our operations in 2017, the total number of spill events to the environment greater than or equal to a barrel increased by 20 percent, largely due to the addition of the Permian Basin asset. To prevent spills in this asset, we started installing automated switches and valves in late 2017 and initiated a tank inspection program on our older, less productive facilities. We expect to complete these efforts by the end of 2018.

The associated spill volume in 2017 decreased by 35 percent year over year, primarily because of pipeline integrity programs in Eagle Ford that seek to improve asset reliability and reduce unplanned losses. After identifying microbial-influenced corrosion (MIC) as the primary cause of Eagle Ford pipeline leaks in 2014, we have reduced MIC damage through regular pigging, periodic biocide treatment and continuous corrosion inhibition. In 2017, Marathon Oil used advanced inspection technologies on 16 miles of pipeline, and conducted 11 low point digs and automated ultrasonic thickness inspections to maintain pipeline integrity in Eagle Ford. We plan to replace several short pipeline segments and use advanced inspection technologies on approximately 34 miles of pipelines in 2018.
