The shares are expected to be sold to investors at a price of US$34.10, according to media reports.
Proceeds will be put to reducing debt, the company said. It is expected that the disposal will complete on May 9.
The share sale, which is part of Shell’s broader divestment plan, follows a prior divestment deal which last year saw it give up direct ownership of interests in Canadian oil sands assets in a US$7.25bn transaction.
In early London trading, Shell 'A' shares were 0.1% higher at 2,581.5p supported too by firmer crude prices which reached up to a four-year high.
