To improve image resolution in the vicinity of the well, 3D vertical seismic profile (VSP) data was acquired at the Atlantis field in the Gulf of Mexico (GoM) to complement the existing towed-streamer and ocean-bottom node (OBN) data. Two unique data challenges require special consideration and innovative techniques in order to unlock the full imaging potential at the Atlantis field: (1) illumination issues related to the receivers being placed in a well that goes through a complicated salt finger; (2) receiver reorientation issues related to the survey’s two-phase acquisition due to receivers being pulled out and placed back into the well. We demonstrate how we mitigate the impact of these challenges through improved XYZ vector fidelity reorientation and least-squares reverse time migration (LSRTM).
