North Sea oil producer EnQuest is looking to raise £30million through new bonds – the firm’s second of the year.
The Aberdeen-based firm raised £145million in February through a similar scheme.
The firm’s chief financial officer, Jonathan Swinney, said they were looking to “diversify” their funding base.
The company announced last week that it is to press ahead with plans to pump more than £4billion into its Kraken oil field development.
The heavy oil field, located east of Shetland, will support more than 20,000 jobs during its construction phase, and about 1,000 jobs a year during its 25-year lifespan.
