Royal Dutch Shell is considering raising more than $2 billion from the sale of a stake in the common facilities at its Queensland Curtis LNG plant in Australia, according to a sale flyer reviewed by Reuters.

“Royal Dutch Shell plc is considering a sale of a 26.25% interest in the Queensland Curtis LNG(QCLNG) Common Facilities - a multibillion dollar investment opportunity,” the sale flyer said.

The sale process is being run by Rothschild & Co and is due to be completed in 2020, the document showed.

Shell declined to comment on what it called market speculation. Rothschild also declined to comment.
