Abstract
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 (L1) and then antiparallel to the optical cable for a second length (L2), said sensor tools being located along the second length (L2) of the electrical sensing component.
