The comments come after Bloomberg earlier reported that ExxonMobil was exploring a $1 billion sale of its Argentina shale assets, a process which started last year.
"The process began in August, it continues to advance and the offers are being evaluated," the source said, asking not to be named as the process was confidential. The person added that the firm had received offers earlier this month.
"At the beginning of February they presented binding offers. There is no time or due date to provide a response to say how the operation continues. They are being evaluated by the shareholders," the source said.
