According to Amac News: ADNOC Drilling's announcement states that this agreement was signed in order to accelerate the program of 144 unconventional oil and gas wells.
The company, through its wholly owned subsidiary ADH RSC LTD, has signed definitive agreements for the establishment of Turnwell Joint Venture (JV) with SLB and Patterson-UTI.
Focusing on the UAE's world-class unconventional energy resources, ADNOC Drilling will hold a 55% majority stake through its wholly-owned subsidiary, SLB will hold a 30% stake and Patterson-UTI will hold the remaining 15%, according to the announcement.
Turnwell was established as the unconventional drilling arm of ADNOC Drilling and has executed a $1.7 billion agreement with ADNOC Drilling to provide drilling and related services for the delivery of 144 unconventional oil and gas wells.
Turnwell sets new benchmarks for the global energy industry. The participation of Enersol companies in this campaign is very important.
 Enersol, the technology-focused venture between ADNOC Drilling and Alpha Dhabi Holdings, has acquired a 67.2% stake in Gordon Technologies.
Turnwell's use of Enersol's technology demonstrates the unique opportunities Enersol has to penetrate and grow in the Middle East market while continuing to strengthen its presence in traditional markets.
