Hibiscus Petroleum has spudded the Sea Lion well after the project was delayed.
The company’s subsidiary, Carnarvon Hibiscus, said the West Telestro drilling rig arrived at the site last week following a 196-mile tow from its original location.
The planned total depth of the well is 1,800metres with the exploration well expected to take up to 30 days.
The first well has been spudded on the Gina Krog field in the Norwegian North Sea.
Statoil said drilling began earlier this week using the Maersk Integrator rig, which will now be in use until 2019.
The milestone is one of many for the company on the Gina Krog development project.
