SITE SURVEY DELTANA
The survey, executed by Incostas, consisted in carrying out high-resolution single-channel and multichannel geophysical and seismic acquisition, to detect shallow hazards that could interfere with the positioning of a jack-up platform, the installation of marine infrastructure and the risks associated with drilling activities, paying special attention to the first 200 m, where there are little or no protection mechanisms against gas blowouts. The analysis of geological risks that could interfere with activity development as planned by the Client, was carried out by interpreting the following products: Bathymetric map, Side Scan Sonar mosaics, Sub-bottom profiler and HR2D digital seismic sections.
SCOPE OF WORK
Information collected and interpreted about the irregular seafloor morphology, as well as shallow sub-bottom strata, indicated that area conditions for the location proposed for infrastructure installation are favorable. Sonar records show exhibit uniform reflectivity. Well prognosis confirmed the existence of faults interpreted in the survey area. Such faults do not represent a risk due to their distance to the proposed exploration drilling location.
