Baptist Drilling

Baptist Drilling

Baptist drilling is one of the manual drilling techniques. It is named after the Baptist Missionary, Mr Terry Waller who invented the technique.

This method is limited to non cemented, sedimentary deposits of sand and clay and will not drill through solid bed rock. Some soft rock can be drilled slowly. For gravel or stones from 1 to 3 cm an open bit can be used combined with sludging. A mayor difference compared to other techniques as the Rota Sludge is that this technique uses 1 ¼” PVC pipes on top of the lower steel drill pipe. Therefore this option is very light and can drill down to 100 meters deep.
