On 1 March 2021, the Prax Group completed its acquisition of Lindsey Oil Refinery, a 500-acre facility on the Humber Estuary in North Lincolnshire, capable of processing up to 113,000 barrels per day across more than twenty different crude types. On the same day, the company announced an exclusive crude oil and feedstocks supply arrangement with one of the world’s largest physical commodity trading groups.
The two announcements arriving together was not a coincidence. Sanjeev Kumar Soosaipillai had long held a clear picture of what Prax was meant to become. Years before the refinery acquisition, he described walking into industry meetings when the company was still small, conducting himself as though Prax were already fully integrated.
“I always pretended as though we were already a fully integrated energy company,” he recalled in a Prax company interview.
Securing Lindsey and anchoring its feedstock supply on the same day was, in that sense, the completion of a long-held operational vision rather than improvised response to an acquisition.
Why Counterparty Selection Matters
Supply partnerships in oil refining are not equivalent to supplier relationships in most other industries. A refinery that runs out of feedstock does not slow down, it stops. The financial consequences of unplanned outages, combined with the cost of restarting complex processing units, make supply reliability a question of operational survival rather than commercial preference.
What Prax needed was the ability to source crude across a genuinely global footprint, blend feedstocks to the refinery’s precise requirements, and maintain delivery commitments when individual supply routes became unavailable.
What Exclusivity Signals
Sanjeev described the arrangement as building toward operational and planning flexibility, qualities that depended not on contractual terms alone but on accumulated understanding between two organisations working together over time.
“The arrangement is an important step in our plans for the long-term growth of the refinery,” he said, “and it will pave the way for us to provide operational and planning flexibility, helping us to continue to deliver an excellent level of service to our customers.”
That framing around long-term growth, operational flexibility, and customer service reflected Arani Kumar Soosaipillai’s growth philosophy. “Success is rarely a solo effort,” she said. “Building strong relationships, whether with colleagues or mentors, has been invaluable.
Crude Diversity and Feedstock Fit
Lindsey processed over twenty different crude types. That range was not ornamental; it reflected the refinery’s ability to shift its crude diet depending on what was economically optimal at any given moment, processing heavier sour crudes when the price differential justified the additional cost, or lighter grades when throughput economics pointed that way.
Maintaining access to that range required a supply counterparty with genuine optionality across crude origins, shipping routes, and blending capabilities. A supplier constrained to a narrow set of crude types effectively narrowed the refinery’s operating envelope. Sanjeev had been explicit that the acquisition was made with integration, not isolation, in mind.
“The acquisition was a natural progression for the Group,” he said, “as it provides us with the opportunity to integrate the refinery and its associated product flows into our company’s UK distribution and retail footprint.”
Supply and the Downstream Chain
The refinery’s supply chain did not end at the processing units. Lindsey distributed products by sea, road, rail, and pipeline, including through the 215-kilometre Finaline pipeline running south to the Hertfordshire Oil Storage Terminal near Hemel Hempstead, from which product could reach Heathrow Airport and Greater London.
Sanjeev described the downstream potential plainly: “The Finaline allows us to deliver multi-products to the Greater London area. Product from the refinery can also be fed by pipeline from Hertfordshire to Heathrow Airport, and as a significant aviation player, we can further cement our reputation in this arena.”
How a refinery ran affected everything in downstream production. A supply partnership that optimised feedstock selection with knowledge of the refinery’s output requirements and distribution commitments produced different outcomes from one that simply delivered crude to the fence line.
What the Deal Illustrated
There is a tendency to evaluate supply agreements on price. Margin mattered, but it was not the only variable that determined whether a supply arrangement worked. Reliability of delivery, breadth of crude optionality, depth of the counterparty’s market intelligence, and the degree to which supply decisions were integrated with operational planning all bore on refinery performance in ways that did not show up in a single transaction.
Sanjeev had spent years describing the Prax Group’s destination before the company had reached it. The refinery acquisition, and the supply deal that accompanied it on the same day, were the moment that picture became operational reality.
“The refinery was still an impossible mountain to climb,” he reflected. “However, we found a solution and it genuinely manifested itself.”
