IN DRILLING most wells while searching for oil, potash, or other products, water is used.
If bentonite (a clay-like substance) be encountered, drilling difficulties arise when water comes in contact with bentonite.
Although it had been demonstrated that if a saturated solution of common salt replace the water such difficulties for a certain bentonite would be removed, the action of other liquids on different bentonites had not been studied.
The results of a considerable number of experiments indicate that motor oil, kerosene or gasoline used instead of water would prove ideal in the prevention of difficulties experienced in drilling-all varieties of bentonite if water could be excluded (the latter in the presence of bentonite would form oil-water emulsions which would be difficult to handle) and that where water must be used the addition of some salt will prove a satisfactory remedy, the'quantity and nature of the salt being specific for each variety of bentonite.
