Potential for Mukuyu-1's Results to be Above Market Expectations, page-94

...possibly in short what I am trying to understand is if, " The density log usually labelled 'RHOB' measures the density of the borehole and the rocks penetrated by the drill bit. " could be affected by mud cakes and overall mud clogging the formation due to malfunctioning equipment?

On this also I am intrigued by the decision to assign drilling contract to different service providers.
Particularly regarding the MUD service....but on this I need to ask another question:
===========================
Geolog International has been awarded the mudlogging contract.

The remainder of the services, including cementing, drilling fluids & mud engineering, tubular
running, fishing & abandonment, liner hangers, reservoir technical services and project
management have been retained by Baker Hughes.
======================
Now in simple words who is doing the Mud Job, Geolog or again BH?
