New York-listed Atwood Oceanics has stretched a deal for a drillship in Africa.

The company said Kosmos Energy Ventures is paying an undisclosed rate for the 64,000-dwt Atwood Achiever (built 2014) to drill one well in North-west Africa.

The deal starts immediately following the completion of the well in progress under an existing contract with Kosmos.

It also includes six one-well options.
