The listing, announced yesterday, could value the firm at over $1bn and would make Fairfield one of the top 10 independent UK oil companies.
Pelham Bell Pottinger won the IPO brief via a competitive pitch. MD James Henderson and directors Mark Antelme and Gavin Davis will lead the account, working alongside Fairfield's head of communications Charles Gordon.
The company will use the funds to boost its oil production around the UK Continental Shelf.
Fairfield expects to complete its listing and be admitted to the main market of the London Stock Exchange in July.
The firm was founded in 2005 to buy North Sea fields that could have their life extended through new technology.
