ENAP Sipetrol Argentina, operator of the El Turbio Este exploration area (Austral-Magallanes Basin, Santa Cruz province, Argentina), executed a 1300Km2 3D seismic acquisition project between November 2018 and March 2019, awarded to contractor UGA S.A. An innovative methodology called CSI (Compressive Seismic Imaging), patented by ConocoPhillips (partner company in the area), was used here for the first time in South America. The CSI project implied changes over the traditional seismic acquisition, such as the use of single source and single sensor per point and simultaneous, unsynchronized independent sweeps, recording these data using nodes. The CSI method includes the separation of these records through deblending, a seismic inversion process to obtain clean individual records. CSI is a variation of the general CS (Compressive Sensing) method, based on a random spatial sampling of the wave field, as opposed to the standard sampling of sources and receivers of the conventional seismic. Using the same number of emission and reception points of a conventional seismic, the CSI method exceeds the resolution limit imposed by the Shannon-Nyquist criterion for regular sampling. CSI obtains the same resolution as conventional seismic using a lower density of points per Km2, or a better resolution using the same. The design of a conventional seismic can be redefined by CSI to meet the same objectives in less operation time or better resolution, or both. CSI allows the recording of several points (blending fold) in the time that only one is recorded in ping-pong mode, thereby achieving higher efficiency. The use of vibroseis sweeping from 1 Hz combined with 5-Hz, high sensitivity single sensors, allowed to obtain a good image of the deeper structures and the top of the basement, normally hard to see in other 3Ds in the region. The use of 17,000 nodes allowed each one of the 10 vibroseis working simultaneously to have a complete receiver template from their positions. Real-time QC was focused on the performance and position of the vibroseis through radio link to the Observer’s central unit. The contractual production of 3,364 VPs/d for a 73-day project was completed in 67 days. With a budget for an equivalent conventional seismic, a 30% larger area was acquired, with excellent data quality and a remarkable time reduction.
