Analysis of factors related to acquisition for deep target exploration

The main challenge in deep and ultra-deep oil and gas exploration is the lack of high-resolution seismic imaging results. The imaging results at these depths are mainly related to the excitation, propagation and reception of seismic waves. For deep and ultra-deep oil and gas exploration, the design of the geometry needs to be adapted. Therefore, an analysis of the factors related to acquisition is required to provide a basic understanding of deep and ultra-deep oil and gas exploration. This abstract analyzes aspects such as the detectability of weak deep signals, the relationship between absorption attenuation and noise with the coverage number and maximum offset in deep and ultra-deep exploration, the relationship between offset and velocity accuracy, and the relationship between the sampling interval of deep scattered waves and aliasing. It also provides some formulae that can be used to design geometry parameters based on data obtained from geological surveys.
