Working together in ZADCO
ExxonMobil, Abu Dhabi National Oil Company (ADNOC) and Japan Oil Development Company (JODCO), co-venturers in Zakum Development Company (ZADCO), are working together to expand development of one of the world’s largest oil fields.
The Upper Zakum field, situated about 50 miles northwest of the city of Abu Dhabi, is currently producing more than half a million barrels a day. Through the collaboration of their professionals, and by applying ExxonMobil’s leading-edge technology, the project could boost daily field production to 750,000 barrels — a sizable contribution toward meeting future growth in global demand.
Artificial Islands in Upper Zakum – safety, environmental and operational benefits
Upper Zakum was originally developed from almost 100 steel platforms — or wellhead towers — in the ocean, from which production wells are drilled. When ExxonMobil joined ZADCO, plans were already underway to significantly expand the production capacity for the field. The original plan was to expand capacity by building more wellhead towers.
Given the local capabilities to construct artificial islands, ExxonMobil assessed the overall cost, benefit and environmental aspects of changing the development plan to be based on islands, equipped with both drilling rigs and processing facilities.
In addition to the many safety and environmental benefits of the island concept, it provides significant operational efficiencies. Several billion dollars worth of savings in development costs have already been identified for the country. In the long-term, existing steel towers can be removed as they become obsolete.
