Marathon Oil wants all of our employees and contractors to go home safely every day. We measure our safety performance, strive for continuous improvement and benchmark our performance against our exploration and production peers.

Safety Performance

Navigate Page: Addressing Major Safety Risks | Process Safety Metrics | Safety Performance Metrics | Total Recordable Incident Rate (TRIR)

Continuously promoting a positive safety culture and emphasizing that our workforce must take personal responsibility for safety, avoid shortcuts and use their Stop Work Authority are essential to achieving an accident- and injury-free workplace.

Our companywide 2015 Total Recordable Incident Rate (TRIR) was our best ever – 0.39 for employees and contractors combined, compared to 0.75 in 2014. Our U.S. TRIR of 0.47 was approximately 30 percent below the industry average reported by the American Exploration & Production Council (AXPC) and compared favorably to our peer companies’ performance. We recorded 23.3 million exposure hours, 26 percent fewer than 2014, primarily in our three U.S. unconventional resource developments. Contractors accounted for 73 percent of all hours worked in 2015.

The primary factors contributing to our improved performance were the ongoing focus by our managers and supervisors on promoting a positive safety culture, and continued strict adherence to the Company’s HES processes and standards. In addition, the reduced activity level decreased potentially higher risk activities such as drilling and completions and enabled us to shift more work to contractors with superior HES performance.


2015 In Depth Global Safety Performance

Addressing Major Safety Risks

After identifying hand injuries as a global trend in our operations in 2014, Marathon Oil promoted awareness of hand safety and proper glove selection. This led to a 66 percent reduction in the number of recordable hand injuries. Notably, Equatorial Guinea had no hand injuries from June 2014 through year-end 2015, although they accounted for approximately 50 percent of recordable incidents in the asset from 2012 to mid-2014.

In 2015, dropped objects caused approximately 33 percent of the Company’s serious events globally. Our HES team found that dropped objects correlate more to activities such as drilling derrick lifts than to mechanical integrity and equipment failure. To reduce the risk of dropped objects, we conducted more work site walkarounds to identify hazards and increased tool inspections. In 2016, the Company is providing additional tools to continue reducing the number and severity of dropped objects incidents.

Process Safety Metrics

Process safety includes programs intended to prevent hydrocarbon releases that have the potential to impact people, property and the environment. It is an integral component of Marathon Oil’s management system. We work continuously to improve our process safety culture and performance, track and investigate process safety incidents and near misses, develop corrective actions and share them across our operations.

In 2015, Marathon Oil recorded one high consequence and three medium consequence process safety events, all on offshore platforms in our UK operations. We shut down a platform for an extended period to conduct a full investigation of the high consequence event and implement corrective actions. The event was a process pipe failure and we continue to investigate the containment loss. Any findings and the resulting corrective actions will be shared across all our operations. No injuries or impact to the environment occurred as a result of the high or medium consequence events.
