Workforce Overview

Our Talent Landscape
Our employees help produce the energy the world needs. We know our current and future success depends on attracting, developing and deploying a diverse, engaged workforce with the expertise to execute on our business strategy.

As of Dec. 31, 2022, we had approximately 1,600 active, full-time employees worldwide. Approximately 73% of our full-time workforce was based in the United States with 27% in Equatorial Guinea. Through recruiting, training, education and vocational programs, we strive to have a workforce reflective of the areas in which we operate. In 2022, and as a result of intentional nationalization efforts, 93% of our Marathon EG Production Limited (MEGPL) workforce was Equatoguinean. See the EG section for more information.

The average tenure for full-time employees was approximately eight years, with approximately 33% of our full-time employee population having 10 or more years of experience.

Introducing Ensign

In November 2022, we announced the acquisition of Ensign Natural Resources, an exploration and production company operating in the Eagle Ford Shale in South Texas. The 130,000 net acres Marathon Oil acquired from Ensign spans Live Oak, Bee, Karnes and Dewitt counties across the condensate, wet gas and dry gas phase windows of the Eagle Ford. This acquisition satisfied every element of our exacting acquisition criteria, uniquely striking the right balance between immediate cash flow accretion and future development opportunity.

We are excited to welcome former Ensign employees to our One Team culture at Marathon Oil and look forward to growing together as we maintain our investment grade balance sheet and deliver on our ESG commitments.
