Mud Logging is a process of recording, evaluating and interpreting the written strip chart which is called Mud Log. Along with the skills of using the Geological Equipment Well site geologists also have educated skill of examining the cuttings of rocks derived from the well.
Approximately 6mm size of rock cuttings are derived from the rock formation of the ground by the drill bit and those cuttings are then driven towards the surface through the drilling fluids that are being pumped out from the holes in the bit.
While the rock cuttings are rising to the surface they are circulating with the rotating pipe of the drill and are mixed with the rock cuttings that are falling back into the hole from the surface.The rock cuttings are travelling then from the mud stream to the shale shaker and then they are driven to the pile which is placed at the base of the shale shaker. The difference in time which is most commonly known as a LAG is very crucial in knowing the type of the rock, as there is time to be calculated of about when the rock was cut away from the walls and by the time it reached the surface.
