Ø Drilling Optimization Technical Service Case Study
SETC’s Drilling Optimization Center (DOC) service model has progressed through several phases, including the pilot testing phase in 2018, block-scale expansion trials in 2019, and full-scale deployment and application in 2020. By the end of 2024, SETC, in collaboration with the clients, had established six DOCs, each capable of simultaneously providing technical service up to 200 wells. Cumulatively, SETC DOCs have provided drilling optimization services for a total of 1,359 wells.
The establishment timeline of the SETC DOCs is as below:
– 2018: RDC established at CNPC Xinjiang Oilfield.
– 2019: Drilling Optimization Centers established at CNPC Southwest Engineering Institute and PetroChina Southwest Changning.
– 2022: Production Command Center established at CNPC Southwest Oilfield Development Division.
– 2023: Drilling Optimization Centers established at CNPC Zhejiang Oilfield and SINOPEC Shengli Engineering Institute.
– 2024: Drilling Optimization Centers established at CNPC North China Oilfield and CNPC Dagang Oilfield.
Domestic Operations:
SETC’s drilling optimization services has covered the eight major oil and gas basins in China, including Junggar Basin, Sichuan Basin, Ordos Basin, Tarim Basin, Bohai Bay Basin and Qaidam Basin.
International Operations:
Beyond the domestic borders, SETC has expanded its drilling optimization services in Oman Area 5 oilfield project by collaborating with local enterprises. This indicates SETC’s capability in applying its advanced drilling optimization technologies in international markets.
In 2020, SETC initiated field trials on platforms XXXH68 and XXXH47 in the Sichuan Basin, achieving a remarkable 48.99% reduction in average drilling cycle times compared to conventional methods. Building upon this success, from 2021 to 2024, SETC expanded the application of its drilling optimization technologies, providing technical support for 130 wells. This broader implementation resulted in an average drilling cycle reduction of 35.20% relative to conventional approaches, underscoring the effectiveness and scalability of SETC strategies in enhancing drilling efficiency and operational performance.
