Saudi Aramco, ADNOC eye oilfield lithium extraction

Saudi Aramco and ADNOC are exploring technologies to extract lithium from brine in their oilfields, Reuters reported on Friday citing sources familiar with the matter.

The attention on lithium, which is used to manufacture batteries, is in line with efforts across the Middle East to diversify away from hydrocarbons revenues and seeks to capitalise on the shift to electric and hybrid vehicles.

Work is in early stages and sources did not detail the type of direct lithium extraction technologies that are under consideration.

Other oil companies have already announced plans to produce lithium. ExxonMobil announced in November 2023 it would start production in 2027, aiming to become a leading producer by 2030.

ExxonMobil is developing its operations in Arkansas, USA, where it acquired around 486 square kilometres on the prolific Smackover formation in 2023. It plans to use lithium-rich saltwater from conventional wells to obtain lithium and convert it to battery-grade material onsite. Produced salt water will then be reinjected into the subsurface reservoirs.
