Surface Drilling
Surface drilling methods are adopted in areas where the drilling location is vacant and has enough space for the drilling rig to set the point. There are various diameters of drilling bits used in surface drilling based on the usage of the borewell. As per current market situation high power rigs are equipped with a facility to drill borewells up to 1200 feet.

Domestic / Home purpose – 4.75 inch, 6 inch, 6.5 inch borewell drilling.
Agriculture purpose – 6.5 inch, 8 inch, 10 inch, 12 inch borewell drilling.
Industrial purpose – 6.5 inch, 8 inch, 10 inch, 12 inch borewell drilling.

Borewell Drilling Procedure:
Drilling procedure of a 6.5 inch borewell is been explained in our draft, the procedure is the same for all dimensions of drilling. The drilling rig is been set exactly in the point marked by a water diviner, hydro geologist, groundwater locator or a borewell point identification expert. Once the drilling rig is set in the point the 8 inch borewell drilling bit is set with the hydraulic hammer which gives pressure for the bits and is forced into the earth surface with the power produced from the high pressure compressor to blast the hole from the surface of the earth until the hard rock formation is hit.

Issues:
Always do not construct any kind of storage tanks or septic tanks near the borewell as it may result in contamination of the well.
If the borewell are not cleaned at least once in two years it may result in blockage of sources.
Gelatin blasting in borewell may end up in complete collapse of the well.
Usage of borewell without installation of slotted casings in silted and boulder conditions may collapse the well, motor may get struck, issues in pumping may occur.
