Energy companies Eni and Jadestone Energy have contracted the same offshore drilling rig for operations in the second half of this year at their producing fields in Australia.

The global drilling contractor Valaris said in its latest fleet update that it had secured two new contracts for its heavy duty modern jack-up Valaris 107.

Valaris did not disclose the operator of the first assignment, but drilling market sourcres said Jadestone is the client and will be using the rig at its Stag oilfield.
