- First means 9 for transmitting and receiving an electrical signal are arranged in the vicinity of the wellhead 15. They comprise a control unit 73, electrically connected on the one hand to the smooth cable 3 and on the other hand to the wellhead 15.

- the current injected by the emission means 9, 11 is between 0 and 10 amperes, preferably between 0 and 2 amperes, under a voltage of 0 to 50 volts, preferably from 5 to 25 volts.
- a current source as used in signal transmissions by stranded electrical cable can be used in this first embodiment.
- An example of a power source that can be used is proposed by the company under the name GEOSERVICES shuttle EMROD ®.
- the surface operator actuates a simple transmitter 9 and the intervention assembly 5 and / or measurements can be provided only with receiving means 11.
- intervention or / and measurement assembly 5 may also include means (not shown) for detecting physical quantities such as temperature, pressure, flow, depth, status of a depth valve, radiation naturalness of the ground ( ⁇ radiation), location of casing joints (“Casing Coliar Locator”) or others.

- the intervention or / and measurement assembly 5 may comprise only detection means and a transmitter 11, the surface then being equipped only with reception means 9.
- the first transmission / reception means 9 on the ground surface 17 emit an electrical control signal in the form of a modulated electric current.
- the smooth cable 3 being electrically isolated from the second conduit 25, a current loop is established between the first transmission / reception means 9, the smooth cable 3, the second transmission / reception means 11, the second conduit 25 and the wellhead 15.
- the electrical control signal is transmitted to the control member 57 of the intervention and / or measurement assembly 5, via the cable 3.
- the active part 55 of the intervention or / and measurement set 5 then executes the command, for example, triggering an explosive charge.
- the second transmission / reception means 11 emit an electrical validation signal in the form of an electric current flowing over the current loop described above.
- This validation signal is received by the first transmission / reception means 9.
- An operator at the surface can therefore receive confirmation of the successful execution of the commanded operation and proceed to the next operation (for example, reassemble the cable and the intervention package and / or measures).

- the smooth cable 3 can be fixed to the exterior surface of the second conduit 25 by clips 75 and positioned during placing the second conduit 25 in the first conduit 21.
- the outer surface of the smooth cable 3 is coated with an insulating material applied permanently. Unlike the installation shown in Figure 1, the deployment means 7 are no longer necessary. The smooth cable is therefore directly connected to the control unit 73.
- a third data transmission device according to the invention is shown in Figure 4. Unlike the device shown in FIG. 1, the surface of the smooth cable 3 has at least one point of electrical contact 81 with the second conduit 25.
- the first transmission / reception means 9 are electrically connected on the one hand, to the smooth cable 3 and on the other hand, to the formation of the subsoil 19, via a pile 83 of conductive material of the electricity, planted in formation 19 on the ground surface 17.
- the pile 83 can be planted in an underwater bottom, if the installation relates to drilling in the open sea.
- the operation of the third device according to the invention is similar to that of the first device according to the invention.
- the first transmission / reception means 9 transmit an electrical control signal.
- This signal is identical to that generated in the first device according to the invention. It can therefore be generated by identical means.
- This signal is injected into a first dipole formed by, on the one hand, the contact point 84 between the cable 3 and the first transmission / reception means and, on the other hand, the pile 83.
- the electrical signal injected into this first dipole gives rise to the propagation, in the grounds surrounding the well of an electromagnetic control signal, in this case an electromagnetic wave, which contains the information to be transmitted.
- This electromagnetic control signal then descends towards the bottom of the well, guided by the smooth cable 3 and / or the second conduit 25.
- This electromagnetic control signal is collected by a second dipole formed between, on the one hand, the contact point 81 of the cable 3 with the second conduit 25 closest to the intervention and / or measurement assembly 5 and, on the other hand, the electrical contact point 87 of the second transmission / reception means 9 with the second conduit 25, the second conduit being electrically connected to the formation 19 by the centralizers 27 and the first conduit 21.
- the electromagnetic signal received on the second dipole generates an electrical signal which is received by the second transmission / reception means
- the validation signal of the intervention or / and measurement assembly 5 is generated in the form of an electrical signal injected on a first dipole formed by, on the one hand, the electrical contact point 81 between the cable 3 and the second conduit 25 closest to the intervention and / or measurement assembly 5 and, on the other hand, the electrical contact point 87 between the emission means 11 and the second conduit 25.
- This last contact point is electrically connected to formation 19.
- the electrical signal injected into this first dipole gives rise to the propagation, in the terrain surrounding the well, of an electromagnetic control signal, in this case an electromagnetic wave, which contains the information to be transmitted.
- This electromagnetic validation signal then rises to the surface, guided by the smooth cable 3 and / or the second conduit 25.
- This electromagnetic validation signal is collected by a second dipole formed between, on the one hand, the electrical contact point 84 of the first transmission / reception means 9 with the cable 3 and, on the other hand, the electrical contact point of the first transmission / reception means 9 with the formation 19 at the pile 83.
- the electromagnetic signal received on the second dipole generates an electrical signal which is received by the first transmission / reception means 9.
- a device for the transmission of data in real time between a tool situated at the end of a smooth single-strand cable of the “piano cord” type disposed in the bottom of a installation of oil production wells and a control device on the surface.
