Abstract
An arrangement for continuously acquiring downhole information from an oil or gas producing well comprises a pipe hanger (18) suspended in the production tubing (2) above its thermal expansion joint (7) and near the production packer (6). A pipe (23) is suspended in the hanger (18) and extends into the producing zones (8,9) of the well. The pipe (23) is carrying instruments (24) for continuously monitoring local well conditions, the instrument signals being conveyed to the top of the well through instrument cables (14) running along the pipe (23), through the hanger (18) and further up along the production tubing (2). The pipe (23) also carries slide valves (25) operable through control lines (27) and packers (28) following the path of the instrument cables (14). These slide valves and packers permit separate testing of the individual production zones (8,9) of the well.
