Fishing Tools
DeepWiki – The well service authority

Special tools for getting lost equipment out of the well. There are some different varieties: Diagnostic, Inside grappling, outside grappling, force intensifiers or jars.
– Diagnostics: May be an impression block, which stamps the top of the lost tool and makes a mark in the impression block to see if there is wire or how the lost tool looks like on the top.
– Inside grappling: which has a profile on it’s body, may be guided inside the lost tool and the profile will attach itself and hold on to the tool until it is realeased at the surface.
– Outside grappling: Also has a profil but inside its body, grabbing around the outside fishneck of the lost tool.
– Force intensifiers: May be an overshot, and is forced with heavy jaring opon the lost tool until it is attached (may only be used once).
