Abstract (en)
[origin: ES8705079A1] A side-entry connection for incorporation in pipe strings, such as a drill-pipe string, and for sealingly passing a cable from the inside to the outside of the pipe string is disclosed. The side-entry connection comprises a connection sub and a sleeve which is slidable inside the axial bore of the connection sub between a top position above said cable entry and a low position in which the sleeve closes said cable entry. Means are provided for retaining the sleeve in each of said positions, and the sleeve includes cutting means at its lower end for severing the cable when the sleeve is moved to its lower position. A retrievable plug is used to close the top of the sleeve and hydraulic pressure is applied to the plug from the surface so as to move the sleeve from its top position to its low position for closing the side entry and for severing the cable.
