The overshot may be a metal mesh device, or a spiral device, one or more round or oval loops, or similar devices that grab on to the pipe exterior.
Logan Oil Tools calls these "external catch" devices. Overshoots or Overshots are fishing devices that fit over the exterior of the well pipe and then grab onto the well pipe exterior to enable lifting the pipe.In the oil and gas industry junk magnets are run into a well ahead of a diamond drilling tool in order to remove metal junk that can damage the drilling bit. Magnets or junk magnets, are sometimes used to retrieve smaller metal objects that have fallen into a well it's doubtful that a magnet could pull a steel well pipe however.Grappling hooks are sometimes used to try to hook onto tools, or other non-pipe-shaped items that have fallen into a well.Augers are drill-type devices designed to retrieve drill components from a borehole by drilling into a verical (dropped) pipe or by wrapping around it.At WELL PIPE RETRIEVAL TOOLS, our home page for this article series, we explain that there are just a few basic types of pipe or junk grabbers used to pull stuff out of oil or gas or water wells: Well Retrieval Tool Designs & Patentsīelow in this article we describe and illustrate some of the classic patented tools and designs that over the last 100 years have typified inventions used to retrieve pipes or other stuff dropped into a well. We also provide an ARTICLE INDEX for this topic, or you can try the page top or bottom SEARCH BOX as a quick way to find information you need. The poly rope shown in our page top photo can be used to pull the well piping from this drilled well - if the rope remains intact.
Pipe grabber tool series#
This article series describes methods & tools bought or home-made that can be used to fish materials out of a water well if you've dropped the pipe, well pump, or tools down into the well casing. Our focus is on water wells, drilled bore holes, steel or plastic well casing designs but these tools also pertain to the oil and gas drilling industry. This article describes and illustrated tools people have invented for retrieving pipes, pumps, tools, or other stuff dropped into a well. History, patents, sketches of devices for retrieving stuff dropped into a well. We have no relationship with advertisers, products, or services discussed at this website. The sticker the Jacuzzi pump is dated 12 April 1995! That's pretty good life in a silty well.InspectAPedia tolerates no conflicts of interest. What I'm getting at is, I recommend the Fetch and actually have a slightly used one up for sale! The drop pipe was schedule 80 pvc except for the top 6" where the galvanized started. After 45 minutes of fishing, the Fetch ended up snagging the pump wire and I was able to retrieve 120' of pipe and a Franklin 1.5hp motor and 15 stage jacuzzi pump. I spent a considerable amount of time fabbing fishing tools and had zero success. Of course, this is our only well that didn't have a rope or cable attached to the pump. Anyhow, I went to pull the pump and the galvanized pipe at the surface broke at the coupler due to corrosion. We had no experience with or knowledge of the well. This particular well was in service when we bought an adjoining parcel to the land we had owned since 1964. In early February, one of them had a problem. We have 6 wells on our property ranging from 150'-480'. I recently got a lesson in fishing and the effects of frugality pertaining to this particular situation. I trolled the site after a broken drop pipe became a reality and I needed some fishing tool ideas.
