First impressions of the data processing of the 2D seismic test survey, totaling 58 km.
Line 3 – 19km
During initial analysis, it is evident that Line 3 serves the purpose of confirming the westerly dip on the structure. The dip is clearly visible, although the precise magnitude is subject to final statics, processing, and depth conversion. The presence of this dip provides valuable information for further interpretation.
The refraction first arrivals in Line 3 indicate relatively slow velocities in the weathering layer (600 m/s) and Karoo sediments (2300 m/s). The base Karoo is estimated to be around 700 m, significantly reducing the depth to the Mulden and Otavi targets. This finding is significant as it helps to assess the feasibility of reaching the desired targets.

Line 10 – 43 km
Line 10 connects with the existing seismic grid and aims to investigate the nature of a large anticlinal structure identified through gravity data in AOI 00. Additionally, the line seeks to determine the effectiveness of Polaris’ Accelerated Weight Drop (AWD) source in acquiring high-quality data in an area characterized by near-surface volcanics.
Initial assessment reveals that the data quality diminishes towards the southern end of the line.
Within AOI 00, a distinct high is observed along the line (point 4), corroborating the gravity interpretation that indicates a closure of approximately 144 square kilometers in this area. This high further enhances the prospectivity of the region and will be modeled using the final data to refine the assessment.
Line 10 also confirmed the existence of an additional structure (Lead 4) which had been tentatively mapped based on the gravity data, adding to the overall prospectivity of the area. This structure will be further analyzed and modeled using the final data, providing a more detailed understanding of its potential.
These initial observations lay the groundwork for further analysis and interpretation. As the data undergoes full processing and additional modeling, we anticipate gaining deeper insights into the seismic characteristics, enhancing our understanding of the subsurface geology and the potential prospects within the surveyed areas.
