Abstract
A wet connector for latchingly connecting an electric cable between surface equipment and a previously installed electrically powered well tool at a remote, downhole location in a well for transmitting electrical energy or signals thereto or therefrom. One form of the wet connector is released electricaly (reverse polarity being used), and another form of the connector is released by tensioning and slackening the electric cable a predetermined plurality of times. Systems using such wet connectors are disclosed, as are methods for their use. The wet connector can be used in conjunction with an electric cable for installing certain tools in a well, especially where it is desirable to deposit such tools gently with no jarring.
