Recently, the YB project YB * * * well was successfully drilled, taking only 12.58 days from drilling to completion. This impressive achievement once again broke the record for the shortest drilling cycle of directional wells in cooperative projects. Looking back at the past, the last shortest record was set on September 18, 2024, by YB * * well with a drilling cycle of 13.98 days. In comparison, the completion time of this drilling was 1.40 days earlier. The successful completion of the well marks a continuous breakthrough in the management level of well engineering technology, fully demonstrating the full chain collaborative combat capability of the well engineering team from technical coordination to on-site execution.
