In July, ADES agreed to pay Weatherford a total of $287.5mln for 31 rigs, eleven of which are in Saudi, twelve in Kuwait, two in Southern Iraq and six in Algeria.
The Saudi-based rigs cost US$92.5mln with nine currently under contra ct and an order backlog of US$78mln.
ADES expects to add new contracts and extensions by the end of the year.
Completion on the six Weatherford rigs in Algeria is also scheduled by the end of 2018.
Mohamed Farouk, ADES’ chief executive, added: “We have now completed the majority of the Weatherford acquisition, which is transformational for the group, significantly increasing our size, visibility and exposure in the onshore market.
"We are also particularly pleased to be deepening ADES' presence in KSA and strengthening our relationship with our strategic customer there who continues to place their confidence in us.”
