Abstract
The invention is a seismic emission device designed to be immersed at the bottom of a water body (sea, lake, etc.), and method of implementation. The device comprises at least one (and preferably several) self-contained emission units (,) immersible at the bottom of a water body, combining at least one or more seismic wave sources (,), such as air guns for example, suited to be placed in contact with the body, local energy storage (,) which supplies the device a multifunction connection cable (,) connecting each self-contained emission unit to a surface relay unit (,), a communication system (,, Y) providing communication with a central control station (,) located for example on a drilling or production platform (,). VSP repetitive exploration operations can be carried out in a well by activating successively the various emission units and by acquiring the signals picked up by receivers R,placed in a well for example and coupled with the formation. The device can be used for oil prospecting.
