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 method for simulating the positioning of at least one acoustic linear antenna towed in a study zone is provided. The method includes at least one simulation step of at least one future position of at least one point of the acoustic linear antenna(e), at least one step for predicting the temporal and spatial variations of at least one marine current likely to interact with the acoustic linear antenna(e) and at least one step for determining the form of the acoustic linear antenna(e) by the resolution of a hydrodynamic model. The prediction step(s) include an upstream phase for determining a current at at least two determined points of the zone; a simulation phase of at least one future position of the determined points; a temporal projection phase of the current determined during the upstream phase at each future position; and a spatial projection phase of the currents at at least two distinct points of the acoustic linear antenna(e) occupying future position(s) of the simulation step.
