The muds act as drill bit lubricant, maintain pressures and carries drilling debris to surface. You remove the mud and the pressure pushing out on the hole reduces. If you suspect casing is required you case a section before moving on. Now they know of a mowry which they will approach with casing methods which isolates the section.
As the mowry is not an area they want to exploit once it is cased off they continue as normal as they’ve created an artificial well bore to travel through unhindered.
