Sudan lost most of its highest producing oil fields when South Sudan seceded in 2011, but it still controls much of the oil infrastructure, including the only oil pipeline for South Sudan to transport its oil resources to the port on the Indian Ocean. The oil blocks remaining in northern Sudan, including the Higlieg fields in Block 4, have been under contention by the two countries. This map shows the blocks under production and the blocks under exploration in Sudan and South Sudan. China, Malaysia and India control the vast majority of the oil being produced in the Sudans. You can click on each block to see the countries and industries that own shares in each block.

The geographical data for the oil blocks originates from the open source OpenOil concession map, geo-coded data showing all oil fields in Sudan and South Sudan, the company licensed to operate the field, and the status of the field. The data on the shareholder companies is 2015 data that was published in a paper, Fields of Control, produced by the Small Arms Survey. The data is found on pages 19-22. The source of the original data is listed as “James, Laura M. 2015. ‘Table of Oil Operations in Sudan and South Sudan.’ Unpublished background paper.”
