Shed, slight correction
Mud logging will be on-going through out the whole well, it covers a lot of "stuff" e.g lots of sensors on the rig to monitor, ROP, Torque, pump strokes etc, also collection of rock cuttings from the mud from which a detailed log is created. When we talk about mud we are talking about weighted synthetic "brown" fluid which is pumped down the drill string and back to the surface whilst drilling, it has several functions, cool and lubricate the bit, well stability as it is at a certain weight to hold back fluids or gas in the strata, hole cleaning (all cuttings are circulated back to surface)
the appearance of the Schlum Wireline shack means they would be carrying out wireline logging, they would only do this in the reservoir to run a suite of tools to gain more information
