Surface seismic data is the most used data type in hydrocarbon exploration and development. Yet, it has some major shortcomings. These shortcomings stem from the requirement that during data acquisition, the sources and receivers are always positioned at or close to the surface. This requirement imposes major limitations on the acquired surface seismic data. The above limitations can be addressed by properly designed borehole seismic techniques. Before embarking on a borehole seismic survey campaign, the big question that is often asked is: what would be the added value from borehole seismic data to the exploration or development project?
