Who we are

Our Business

Our core business is refining, logistics and sales; our assets and investments complement and enhance these activities. At the last count, we have 1250 employees with head office in Poland.

We are driven by the needs of our customers around the world and the desire to fuel their journeys. To this end, we utilise our global capabilities across our integrated midstream and downstream energy businesses – from retail to storage, aviation to wholesale, marine to bunkering and beyond.

The Corem Energia Group refines and blends physical oil to regional, market and customer specification in strategically located terminals and warehouses around the world. We operate efficient, safe, and high-quality logistics, moving oil by barge, truck, rail, pipeline and vessel in support of our core activities and for third parties.

To make things simple for our customers, we segment our businesses into four distinct, but integrated, divisions:

  • Integrated Supply & Optimisation
  • Financial Integrated Supply & Risk Management
  • Refining
  • Distribution

The Corem Energia Group’s downstream marketing and distribution businesses carry the Corem Energia Energy brand. Our midstream and upstream businesses, including refining, processing and blending, carry the Corem Energia brand. The Group is collectively identified as The Corem Energia Groupp.

Know Our Company

We have a set of core values which we believe form the basis of our business and which act as a code of conduct for us all, as we go about our working lives. Our core values are as follows:


Integrity – We encourage good work ethics

We encourage good work ethics and believe that our dealings with others must be done with integrity. We are fully transparent, fair, honest and upfront in all interactions.

We have a reputation of excellence in everything we do and we are committed to maintaining this. Our aim is to be best in class in every aspect of our business, most importantly our ongoing commitment to maintaining the highest standards of Health & Safety right across the company. We are led by a highly respected and remarkable team, all of whom have a deep understanding of the energy industry.

Principled & Passionate – We take pride in our business and heritage

Although we are very modern in our approach, we are passionate about maintaining old-fashioned values and principles that ensure we are a loyal, dependable and compassionate organisation. We are service-orientated and we value relationships. We advocate and uphold high environmental standards and sustainability practices. Our focus is always our customers, whoever and wherever they may be, but we also value and support our staff – after all, if they succeed, we succeed.

Drive & Dynamism – We endeavour to be world class and have a “can do” attitude to get the job done

Our success has been achieved through our entrepreneurial spirit, dynamic team and lean structure. We are independent, driven and forward thinking – passionate about our products and with a perpetual quest for quality performance across the board. Our people are what make our company great and we consider them family.

Philanthropic – We promote a culture of generosity
