Overflow Drilling
I have had this problem in the past and the use of bentonite is the key. The problem is how to place the seal. What has worked for me in the past, depending on the size of casing is to use bentonite plugs. Pellets and tablets will probably get washed out, the same applies to bentonite grouts...- mudman
