Mud pits and ditches

Mud pits and ditches 

Mud pits and ditches are designed to reduce 

the velocity of the drilling fluid to a point where 

the cuttings will settle to the bottom and not be 

carried to the pump (Fig. 4). We do not want to 

recirculate any sand in our fluid if possible as 

this causes excessive wear on all equipment in 

and through which it passes. Another point is 

the high weight created by the sand content 

causes sealing of the formations with pressures 

not necessary
