SLUDGING WITH TEMPORARY CASING

These videos show an interesting technique in which a series of progressively smaller casings are used to overcome the friction that would result from a long hole in the sand.  First, a four inch casing is worked into the sand.  Then a three inch casing is extended beyond the depth of the four inch casing.  Then, an even longer 2 1/2 inch casing is inserted inside the three inch casing.   Each of the casings are worked into the soil/sand by bailing sand from the bottom of the hole with a 1 1/4 inch bailer that will fit inside any of the three casings.   Finally, when sufficient depth is reached a well screen is inserted and all three of the progressively sized casings are removed.

This is an excellent example of using good old ingenuity to overcome a lack modern equipment.
