Total’s likely decision to proceed with a $5.1-billion Ugandan oil project will extend its dominance as the biggest spender in sub-Saharan Africa. The French energy giant, poised to greenlight the plan within days, has been the largest investor in the region since 2012. Its spending on exploration and production there peaked at $6.2-billion eight years ago, and even following the latest downturn will be around $1.9-billion in 2021, Wood Mackenzie data show. That’s more than double any other international producer.
