section 107 and a non vertical wellbore section 110 the wellbore is lined with casing 112 installed over the well is a rig 115 placed there to facilitate the insertion of a tool or tools into the wellbore a truck 120 is shown with a reel 122 of wireline that can be directly placed in the wellbore via a block and tackle assembly 125 of the rig at a lower end of the wireline 130 in the non vertical section 110 of the wellbore is a tool 135 like those described herein the tool is designed to be located via the wireline at a predetermined location in the wellbore and then fixed to the wall of the wellbore by remotely actuating a slip and cone assembly not shown built onto the tool in one instance the downhole tool is a plug with a central bore that can be temporarily blocked in a single direction during an operation in a wireline installation the plug is typically actuated or set using a setting tool 137 schematically shown at an upper end of the tool the setting tool includes a charge or some chemical compound that creates a force used to cause one part of the tool to move in relation to another part thereby setting the slip the action is initiated from the surface of the well by a signal that travels down a conductor in.
