In my last article, I discussed the use of wireline cutters and a combination socket. This same tool can be used to retrieve tools that have come unscrewed. The combination socket will have to have different slips installed to catch a tapered male tool joint, but these are available.
Last month, I wrote about fishing for tools that were loosely lodged in the drill hole or perhaps for a bit wedged into the casing shoe by a stone, pebble or what have you. This month, we are going after a string of tools that is really stuck for whatever reason, and either contains no drilling jars or the drilling jars have become stuck.
In
my last column I talked briefly about fishing for food on the ice and that one
had better be careful how thick the ice was or they could be in a rough spot.
Dear
readers, I’m writing this in very early January 2013 and although you will read
this a little later, I hope you had a prosperous and safe holiday.
Although
I have been talking about well casing and drop pipe in several recent columns,
I did wander off with some thoughts about conventions of the past last time.
With
the 2012 National Ground Water Association (NGWA) Groundwater Expo set for Dec.
4-7 in Las Vegas, I have decided to write a few thoughts about previous NGWA
conventions that I have attended.
"One of the most important parts of a properly constructed water well is the casing, even if bedrock is very near the surface, and collapse of the borehole is not going to happen in that formation."
