3D SEISMIC ACQUISITION METHOD WITH SINUSOIDAL GEOMETRY

摘要

The present application relates to a 3D VSP terrestrial or marine seismic acquisition method, characterized in that the method comprises the following steps: locating the energy sources by following a sinusoidal geometry; locating the receivers with the geometry of the well by following a sinusoidal geometry; forming the source and receiver lines in accordance with the sinusoidal geometry by forming the study plot with equally spaced sinusoids and with a constant or variable initial phase; initiating seismic waves from the sources, and recording the reflected or converted energy coming from the subsoil in the receivers. The sinusoidal geometry is governed by the following equations: formula (I)
