Profile

A new beginning starts with one step.

Each step moves us closer to creating long-term growth for our customers, shareholders and employees.

Each step will prove us a trusted partner.

SemGroup® Corporation is a publicly held company that moves energy through a network of pipelines, terminals and storage tanks. Each step we take demonstrates the vast experience of our employees, their dedication to add value to our customers’ business, and their desire to bolster our relationships.

SemGroup provides gathering, transportation, processing, storage, distribution, marketing and other midstream services primarily to independent oil and natural gas producers, refiners of petroleum products and other market participants located in the Mid-Continent and Rocky Mountain regions of the United States and in Canada, Mexico and the United Kingdom. SemGroup will continue to focus on the emerging shale markets and, with our equity stake in NGL, the company’s combined capabilities allow us to better serve our producers and end-use customers. SemGroup also serves as General Partner of Rose Rock Midstream, L.P., a limited partnership recently formed by SemGroup Corporation to own, operate, develop and acquire a diversified portfolio of midstream energy assets.

With the common root word “sem,” meaning one, the SemGroup family of companies is committed to a “zero incident” culture, with employees working to keep the public, and each other, safe.

Our business – safely moving energy throughout the United States, Canada, Mexico and the United Kingdom.

Our passion – creating one team with our customers and giving them seamless connectivity between the energy they produce and the end users.

Take a step with us. We will deliver.
