Abstract
The present invention generally relates to an apparatus and method for seismic monitoring. In one aspect, an apparatus for acoustically coupling a sensor mechanism to a surface in a wellbore is provided. The apparatus includes a mandrel disposable in a tubing string. The apparatus further includes a carrier member disposed on the mandrel, the carrier member axially adjustable relative to the mandrel. The apparatus also includes at least one sensor mounted on the carrier member, the at least one sensor connected to the surface of the well via a cable line and a deployment assembly disposed on the carrier member for coupling the at least one sensor to the surface of the well. In another aspect, a method for acoustically coupling a sensor mechanism to a surface of a wellbore is provided.
