In the Rig.......................

After Stuck up........
Arrangement for spotting job
The chemist opened a drum of Spotting fluid to put it into the slug tank
A black coloured liquid came out
Schlumberger DD asked, "What is this"
Chemist replied, "Spotting Fluid"

Chemist opened another drum.........
This time a Yellowish gray liquid came out
Again the DD asked, "What is this"
Chemist replied, "spotting fluid"

Chemist opened the 3rd drum.......
A colourless liquid came out......
DD asked, "Is it also spotting fluid"
Chemist replied, "Yes , this is also Spotting fluid"

An astonished DD asked, " Why the colour of the 3 spotting fluids are so different?"

Chemist politely replied ,"The 1st one is distilled , 2nd is double distilled & 3rd is highly purified triple distilled spotting fluid"

Schlumberger DD fainted !!!!!!

.........As usual Stuck up not released in that spotting.........
