‘Fishing’as a Petroleum(Drilling) Engineer
Fishing in Petroleum Engineering In Petroleum Engineering, Drilling
Engineers use the term ‘Fishing’ to recover any objects accidentally lost/dropped in an oil/gas well
The ‘fish’ could be anything including drill-pipe, drill bits, cable, tools and junk.
‘Fishing’ requires ability to identify the ‘fish’, and design a retrieving tool to recover the fish (think rod, reel & hook! No bait required)
Steps in ‘Fishing’ Identify the fish and obtain information on
the size, dimensions & “latch on” characteristics.
Design or select an appropriate fishing tool Use tool selected to locate, latch and
retrieve fish Finally, as with fishing, be patient – trial and
error & improvement is required.

Activity - Time to go fishing! Two wells Gusher #1 &
Gusher#2 are being drilled in Million-Barrel Oil Field.
Both wells have ‘fish’ in them
Your task is to retrieve the fish and continue drilling so that you can produce your well first.
<- Gusher#1
Gusher#2 ->
Time to go fishing! Identify fish
Use Playdough ito create an“impression” block to identify fish
Time to go fishing! Select/design an appropriate fishing tool
based on fish identified
Time to go fishing Insert fishing tool into
well and try to retrieve ‘fish’
Time to go fishing! FISH ON !!
Fishing Challenge!Horizontal well fishing ! Retrieve the fish from a horizontal well!
Did you know?Horizontal wells in the Barnett Shale in North Texas are drilled ~7000’ deep and ~3000’ laterally!Horizontal wells in the Bakken Shale are drilled 10,000 ft (~ 2 miles) deep and 10,000 ft (~ 2 miles) laterally!
Being a Petroleum Engineer Petroleum Engineers have many sub-
specialities. Drilling Engineers drill for oil/gas. Reservoir Engineers calculate the amount
of oil/gas and the best way to produce the oil/gas.
Production Engineers produce & transport the oil/gas.
