An oil and gas company operating one of the world's longest crude oil pipeline systems faced business challenges due to legacy processes and systems. The company transports crude oil and refined petroleum products equivalent to 13% of US crude oil consumption and 65% of Canadian production. However, sub-optimal allocations caused high apportionment and diversion of nominated volumes to pipelines of competitors, leading to revenue loss. The company faced a business imperative: manage the complexity of operations while enhancing business performance. The company sought to optimize operational costs, improve capacity utilization and mitigate business risks by undertaking a transformation program. It partnered with Infosys to retire legacy processes and systems and transform the technology landscape.
