Apparatus for use in conducting well workover operations includes a coiled non-electrically conductive matrix shaped into a string and containing at least one conduit capable of conducting fluids and electrical conductor means capable of transmitting electrical energy through said matrix. Tool means for performing well operations is connected to the matrix string. Preferably, the matrix string contains three conduits. A variety of workover methods may be carried out using various tool means.
