A hybrid sensing apparatus for collecting data inside a well, the apparatus including an optical cable that acquires a first set of data; and an array of discrete probes connected to each other with an electrical cable. The discrete probes are configured to acquire a second set of data. The apparatus further includes an attachment system attached to the discrete probes and configured to hold the optical cable. The attachment system is configured to expose the optical cable to directly contact the well.

Hybrid sensing apparatus and method

A hybrid cable for collecting data inside a well includes an electrical cable extending along a longitudinal axis of the hybrid cable, an optical fiber extending along the longitudinal axis, an armor that extends along the longitudinal axis, and encircles the electrical cable and the optical fiber, and a connecting device extending along the longitudinal axis, to enclose the electrical cable and the optical fiber, and to be enclosed by the armor. The connecting device has an unsmooth external surface.

Hybrid cable with connecting device

A hybrid sensing apparatus for collecting data. The apparatus includes an optical sensing component having an optical cable that acquires a first set of data and an electrical sensing component having sensor tools that acquires a second set of data. The electrical sensing component extends parallel to the optical cable for a first length (L) and then antiparallel to the optical cable for a second length (L), said sensor tools being located along the second length (L) of the electrical sensing component.
