How to Read a Mud Log — Swan Energy Learning Center

Having a basic understanding of a mud log can be a valuable skill for anyone that participates in a oil and gas venture.

A mud log is a detailed report of the well bore by examining the rock cuttings and mud that is brought to the surfaces as the well is being drilled. Usually, mud logging is conducted by third party. The use of hydrocarbon gas detectors are used to record the amount of gas that is brought up in the mud. These gas levels can be seen on the mud log.

Mud logging is the observation and microscopic examination of of the drill cuttings and evaluation of the gas hydrocarbons and its constitutes, as well as collecting other information about the chemicals and drilling perimeters.
