Procedure
The casing is made by cutting the PVC pipes of its desire dia & length.
The homogenous reservoir is made by making a formation with the help of
different types of rocks.
Depth can be calculated by moving tool in borehole with the help of gear motor in
clockwise & anti-clockwise direction.
Time can be calculated on stop watch when tool travels the cycle of motion in
borehole.
The programming on Arduino helps us in acquiring & processing gamma ray log.
The model is first simulated on protous software in order to get correct readings.

Results
We have presented a concept of casing by using PVC
pipes of different dia.
 Different types of rocks in aquarium is clearly showing
the homogenous reservoir.
 We have accomplished our task of displaying Gamma
ray log on LCD.
The maximum value on log is presenting the shale rock
while minimum value is the interpretation of sandstone
rock.
LCD is also showing the depth, as the tool is moving in
downward & upward direction through the movement of
gear motor in clockwise & anti-clockwise direction.
Tool takes 4 seconds in completing half cycle of motion
in borehole.
