About Us

SEF Energy is a private holding company with a portfolio of U.S.-based oilfield manufacturing assets. We’re in the business of delivering returns through methodical capital allocation, asset management and leadership. Our strong financial backing, conservative investment strategies and hands-on approach provide stability and durable, long-term growth for our companies.

SEF Energy was established in 2014, but our ties to the industry go back over 40 years. We are headquartered in Oklahoma City and serve energy companies in Oklahoma and throughout the U.S. We are proud to be a part of the Oklahoma energy landscape and contribute to our state’s economy. The Seven Eagle Feathers found in our state flag inspired our company’s name and serves as a reminder of our heritage and responsibility to our stakeholders.

A Values-Based Approach

The enduring success of our companies relies on our leadership, the culture we create and the core value system we share. Our mission is to be the best at what we do. This requires collaborative, long-term relationships with our customers and a solid foundation for our employees to succeed.


At SEF, leadership is a common objective and a shared responsibility.  We endeavor to develop leaders at every level of the organization. We prize and praise our collective success over individual accolades. Our leaders are servants working to advance the goals of the people around them and the organization!

Team-based Culture

Our people are our most valuable asset, and we succeed together. We drive an energetic, team-based culture through focus, integrity, and accountability. Our culture is predicated on adherence to our core value system.

Core Value System

Our value system sets the standard for the conduct of our organization and serves as the foundation for our culture. We believe that creating, fostering and maintaining the right culture is the most important factor in determining our success. The fundamental tenets that underpin our culture are our core values.

Our Core Values

Austere – We will be rigorous and disciplined in our cost management
