Sonadrill Holding, the joint venture (50/50) between Seadrill and Sonangol, has secured a nine-well contract with six one-well options in Angola for its newbuild drillship Sonangol Libongos.

The estimated total contract value is $101m with commencement expected in the Q3 and running through to early 2021.

The ship is the first of two Sonangol-owned drilling ships to be bareboat chartered to Sonadrill along with two Seadrill-owned or managed units. Seadrill will manage and operate the four units on behalf of Sonadrill.
