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.
