Risks in drilling a well

Drilling a well can be risky and there are several hazards involved in drilling operations. Some of the safety risks involved in drilling operations include harsh weather conditions, fire and explosions due to the large quantities of flammable materials, electric shock, geological faults and structures, pipe sticking and drill pipe failures, lost circulation, borehole deviation, pipe failures, borehole instability, formation contamination, hydrogen sulfide or other gas, hydraulic fracturing, buried valleys, and man-made features¹²⁴⁵⁶.
