  On April 1, the Tarim Basin ultra deep lateral drilling well Aotan 1C, which was constructed by Daqing Drilling Company, successfully completed the deepening operation. The completed drilling depth of the well is 9522 meters, with a vertical depth of 9406.16 meters and a maximum inclination of 57.5 degrees, setting a new record for the deepest drilling depth in Daqing and the deepest drilling depth inside the pipeline. It once again breaks the record for the deepest vertical depth of a highly inclined well in carbonate reservoirs in Asia, marking a new level of development for China Petroleum in the exploration of ultra deep carbonate reservoirs, with supporting technologies for ultra-high temperature, ultra-high pressure, and ultra deep drilling projects.
