Next to the open well, one can drill a 4” diameter borewell, with compressor fitted stand drilling rig. In that case, it is not necessary to take the rig very close to the point of drilling. But you can drill only upto 250-300 feet using this method. Inside the openwell, drilling is not required as there would be lots of management issues in future.
