From well planning to well execution, the record breaking Mississippi Canyon 822#14 3D Vertical Seismic Profile (VSP) at the Thunder Horse Field in the Gulf of Mexico has been extremely valuable for overcoming resolution challenges and bridging illumination gaps in the surface seismic data. The VSP has been influential in key decisions, such as future well targeting, calling total depth (TD) of hole-sections in a challenging Pore Pressure/Fracture Gradient (PPFG) environment, and framing volumetric upside & downside potential for future wells. The VSP accomplished its primary goals of providing a high-resolution image compared to surface seismic and proving the viability of Independent Simultaneous Source (ISS®) technology for future offshore VSPs, a potential huge cost savings for future acquisitions. The key uncertainties targeted by the well bore survey were thin beds below detection and sub-seismic faults. Additionally, the unique acquisition geometry of the VSP provides illumination uplift over surface seismic that is negatively impacted by current infrastructure and the salt canopy, which overlies approximately one third of the Thunder Horse South structure.
