PGS Ramform Titan survey vessel is about to proceed acquisition of the Campos Deepwater GeoStreamer X, a prefunded MultiShopper 3D seismic survey with multi-azimuth protection. In December 2020, PGS will resume operations, to accumulate a further eight 400 sq km. This survey offers the primary 3D seismic for 17th Round blocks.
Ramform Titan will once more be configured with 14 multisensor streamers, every 10.05 km lengthy, the most important unfold ever towed offshore Brazil. This configuration minimizes the variety of supply factors per sq. kilometer and reduces the variety of acquisition days. Both these measures scale back environmental affect.
This survey will present the primary 3D seismic information over blocks provided within the upcoming 17th Bidding Round, now scheduled for October 2021.
The Campos Deepwater GeoStreamer X undertaking combines new and legacy 3D information, offering a step-change in picture high quality by delivering high-quality, long-offset, multi-azimuth seismic information over the deepwater portion of northern Campos Basin.
• Open acreage provided within the 17th Bidding Round
• Presalt open acreage adjoining to Albacora and Marlim Leste fields
• Areas acquired and below contract within the 14th Bidding Round, with drilling operations underway to check giant presalt buildings
The program makes use of the newest PGS acquisition and imaging improvements together with legacy library information. When accomplished, the survey will cowl roughly 14 900 sq. km.
The tailor-made acquisition configuration for this GeoStreamer X undertaking will present 10 km lengthy offsets to enhance depth velocity modeling accuracy of the post-salt, salt, and presalt sections, facilitated by means of PGS Full Waveform Inversion (FWI) applied sciences.
FWI modeling outcomes point out these lengthy offsets will help in derived velocity accuracy within the presalt part. These extra offset information additionally promise added angle vary and improved sign/noise for seismic amplitude evaluation and reservoir characterization. Multi-azimuth processing and velocity mannequin constructing will enhance illumination and picture high quality of the subsurface buildings discovered inside the presalt play on this portion of the Campos Basin.
Phase 1 full integrity imaging shall be out there Q1 2021, offering last multi-azimuth merchandise over open Pre-salt acreage, together with TTI Kirchhoff and RTM (45 Hz) PSDM merchandise.
