Macquarie Group is understood to have launched the sales process for a stake in Crux gas field of Seven Group Holdings Limited (ASX:SVW), with flyers sent to prospective bidders in the past week. Seven is selling a 15% interest in Crux through Macquarie. The promotional material for the sale is due to be with prospective buyers now.

International groups are expected to be the most likely suitors and will need to shell out at least $250 million to secure the interest. The sale is being launched at a time when energy supply is considered more critical amid the war in Ukraine and as oil and gas prices rally in recent months. Asian buyers are expected to be in the mix.
