What drilling, logging and mud logging work does PetroChina have?

Drilling: It is difficult to be responsible for drilling and installing drilling rigs and other equipment, especially front-line workers, who work in shifts day and night and work 24 hours a day. Generally speaking, they will stay at the scene for a long time.

Logging: Data such as mud and rock formation need to be obtained when drilling, so logging engineers give some underground geological information according to mud and cuttings information while drilling. About the same as drilling time.

Logging: A section of open hole has been drilled, and geologists usually need to know some physical characteristics of underground rocks or information such as oil, water and gas, so they will log. They put the logging instrument into the well through the winch to measure, and then quantitatively obtain the underground geological information, so as to prepare for the subsequent production calculation. The recording time is usually short.
