State-owned Abu Dhabi National Oil Company (Adnoc) has awarded integrated rig-less drilling services contracts worth $763.7m to boost production capacity.

The five-year three contracts for integrated rigless services have been awarded to Schlumberger, Halliburton, and Adnoc Drilling, a subsidiary of Adnoc.

The contracts include services for six of Adnoc’s artificial islands in the Upper Zakum and Satah Al Razboot (SARB) fields.

The six artificial islands include Asseifiya, Ettouk, Al Ghallan, and Umm Al Anbar in the Upper Zakum field, and Al Qatia and Bu Sikeen in the SARB field.

Adnoc said that this investment forms part of its efforts to boost production capacity to five million barrels per day (mmbpd) from these fields by 2030.

Under the contracts, the firms will provide coiled tubing services with thru-tubing downhole tools and stimulation services including equipment and chemicals/fluid systems.

It also covers surface well testing services, wireline, and production logging services and tools, saturation monitoring, and well integrity.

Adnoc upstream executive director Yaser Saeed Almazrouei said: “These important awards for integrated rigless services will drive efficiencies of drilling and related services, and optimise costs in our offshore operations as we ramp up our drilling activities to increase our production capacity and enable gas self-sufficiency for the UAE.

“The contractors bring best-in-class expertise and technologies with a proven track record in the industry and ADNOC Drilling’s scope reflects its expanded service profile following its successful transformation into a fully integrated drilling services (IDS) company, enabling it to offer its clients start-to-finish well drilling and construction services.

“Importantly, the high In-Country Value generated from the awards will stimulate new business opportunities for the private sector and support the UAE’s post-Covid economic growth.”
