Can hydrogeology or satellite mapping help identify the point for drilling a borewell in Kadapa, Andhra Pradesh?

How can I identify groundwater points/location for drilling borewell; as well the approximate depth ?  

I want to drill a bowel at Kadapa, Andhra Pradesh. Water diviners use sticks, copper ring, coconut etc., to identify the source. Which of these is reliable?

Is there a scientific way like hydro-geology or satellite mapping available for us common people in Kadapa area. In our case they used sticks and we did not get water at both points shown by 2 water diviners. We drilled 450 feet and 600 feet respectively and failed both points. They had promised water availability of about 3000 gallons at 350 feet and 500 feet respectively.  I guess this could be a question in many peoples' mind.

So can someone guide us by saving cost of borewell drilling at wrong places/points?
