Method for evaluation of tilt and shift of a well

Lateral shift of a well, without any occurrence of tilt, may take place in very specific occasions. In general, firstly tilt occurs. During or after sinking, while the tilt is rectified partly or fully, shift occurs automatically. Shift is generally a result or product during rectification of tilt of the well. Occurrence of both 'tilt' and 'shift' in a well depends mainly on the characteristics of the soil as well as the method and skill for sinking of the well. In a well, Indian Roads Congress (IRC) code allows tilt up to 1 in 80 and shift up to 150 mm at base. Shift at top of the well is the criteria mainly to accommodate the pier/abutment on the well cap top. For the 'tilt' and 'shift' beyond permissible limits, the design criteria of the well must be verified by the designer. For verification of design of the well, it is necessary to find out the correct resultant 'tilt' and its direction angle with the axis. The resultant shift at base is also required to be calculated for verification. Clarifications and method of calculations for finding out both 'tilt' and 'shift' of a well have been made in this paper, which may help the young engineers at site.
