Muds, hydraulics and lost circulation for Slim Hole Drilling - Continuous coring
Muds are a critical part of an optimised slim hole drilling system. The design of the mud for all slim wells must be closely integrated with the hydraulics program, which is in turn closely integrated with the mechanical design of the drilling, evaluation, and completion system. These interfaces are much more complex than with conventional holes.
1 Muds for continuous coring
In general, the mud requirements for a continuous coring system are much more severe than for a downsized conventional system.
