About Principles and Actuality of Combining Surface and Downhole Acquisition Geometries (3D+VSP, 2D+VSP)

This paper is considering the oil and gas deficit problem and also actuality of increasing of extraction coefficient. Increasing of detail level and precision of productive layers exploration presented as a clue. Surface and downhole acquisitions disadvantages and advantages are discussed. Combining of surface (2D, 3D) and downhole (VSP) acquisitions geometries advantages as part of third dimensional acquisition system suggested as the way. Using of these benefits provides possibility of increasing of productive layers exploration resolution for twice.
