ExxonMobil Guyana’s offshore oil developments are progressing with record efficiency, enabling faster project execution and greater economic benefits for the country. This is according to its President, Alistair Routledge, in an exclusive OilNOW interview.
He said the company has refined its processes to deliver projects faster and more cost-effectively. “The development supply chain has become incredibly efficient in how we’re delivering deepwater projects here in Guyana,” Routledge said. “One project is starting to enable the next.”

Since the first discovery in 2015, ExxonMobil has sanctioned eight projects in just 10 years. The first three developments were completed ahead of schedule and on budget, while the next three are progressing on target.
By standardizing operations, the company has improved execution. “It’s more of a manufacturing process,” Routledge explained. “We drill many of these projects, in excess of 40 miles per project, and relay many, many miles of flow lines for every development.”

Beyond the floating production, storage and offloading (FPSO) vessels, each project involves complex subsea infrastructure, including umbilicals, risers, and flow lines. ExxonMobil’s ability to repeat and refine these steps across multiple developments is driving efficiencies unmatched elsewhere in the oil industry.
“By being able to repeat these over multiple projects, we’re achieving efficiencies and performance that nobody is seeing anywhere else in the world,” Routledge said.
