There seems to be some who think using drilling mud is feasible if it is relatively clean, while others think it is not worth the risk. Any more opinions or experience on that?
Drilling mud comes in 2 forms. Dry powder, and wet (mixed with water). Both are edible, though not especially tasty. As mentioned, sometimes there are additives to improve the mud properties. These days, it is much less likely that any harmful products are added. Check with the drilling company, they will know exactly what's in it and whether it poses any threat to fish. A little NaOH is harmless, high percentages would need neutralizing with an acid before use.
In the end, using mud dry or wet would get the same result.
