Who we are

Our History

Our Business

Our core business is exploration and production, refining, logistics and sales; our assets and investments complement and enhance these activities. At the last count, we have 1450 employees in 8 offices across the world.

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 upstream, midstream and downstream energy businesses – from exploration to refining, retail to storage, aviation to wholesale, marine to bunkering and beyond.

The Prax Group makes discoveries in naturally fractured basement reservoirs, feeding this product further down the value chain. We also refine and blend 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 three distinct, but integrated, divisions:

  • Upstream
  • Midstream
  • Downstream

The Prax Group’s downstream marketing and distribution businesses carry the Harvest Energy brand. Our midstream and upstream businesses, including refining, blending, exploration and production, carry the Prax brand. The Group is collectively identified as the Prax Group.

Our branding, identity and logos explained

The outer circle of the Prax logo is reminiscent of the globe and depicts endurance. The inner circle represents a bird’s eye view of an oil storage tank; this lean but incredibly strong structure epitomises the collective strength of the Group.
 The colour green suggests a connection to nature and the environment, while the name Prax is taken from the first initials of members of the founders’ families.

Axis Logistics is a seal of approval and a promise of quality and expertise. An axis is the invisible line around which an object rotates, much like the rotating elliptical circles of our logo, which symbolise the speed, power and innovation for which the company is renowned, serving the fast pace and demands of the changing energy industry. The colour green represents our commitment to minimising, as far as possible, our impact on the environment.

The concept behind the design of the Prax Foundation Roots logo is a tree, which has strong foundations and branches made up of the children that the charity supports. The tree represents their personal growth, and the help and support they are offered in order to put down solid roots of their own. It is also reflective of the charity name, which stems from the fact that our trustees have roots in Sri Lanka.

Butterflies play a number of important roles in the ecosystem and from ancient times, the remarkable metamorphosis from chrysalis to butterfly has been used to illustrate rebirth and transformation. The Harvest Energy butterfly logo represents the continuous, steady evolution of the business and enhances its environmental credentials.

The Breeze logo depicts two leaves, used in different colourways – blue and green – representing the synergies between the brand and Harvest Energy. The leaves suggest a connection to nature and the environment, while the simplicity of the Breeze logo represents the ease and efficiency of using our facilities.

The clarity and simplicity of the OIL! logo represents the comprehensive service offered at the brand’s forecourts. The logo’s use of green represents the environmentally conscious values that are at the heart of the business, while the use of violet reflects the changing colour of the sky at night – indicative of a commitment to service excellence 24/7. The interplay between the two colours is symbolic of a fuel tank being filled up, highlighting our clear focus on serving the needs of our customers. Meanwhile, the exclamation mark symbolises our dynamic approach to changing needs in the regions in which we operate.
