Mark Webber has now signed a one-year extension to his Red Bull contract.
The Finnish newspaper Turun Sanomat said the 34-year-old Australian's 2012 deal will be announced in Hungary this week.
Earlier, it was rumoured that another driver, perhaps Lewis Hamilton, might be drafted in to replace Webber as Sebastian Vettel's teammate.
But team owner Dietrich Mateschitz said recently that Webber, who achieved pole at the Nurburgring and outperformed Vettel all weekend, is staying put.
"I always said that I expect our 2012 driver lineup to be the same," team boss Christian Horner told F1's official website, adding that the news becoming official is a "formality".
"I am very happy with the two drivers we have. They push each other hard and I can't imagine any other driver in our car, or Mark Webber in any other team's car next year," he added.
