Resolution Improvement Processing of Post-stack Seismic Data and Example Analysis - Taking NEB Gas Field As an Example in Indonesia

with continuous advance in reservoir prediction technology, the requirements for inversion accuracy are higher. It requires that seismic data must have features such as high fidelity, high SNR and high resolution. How to ensure the improvement of seismic data resolution on the premise of not reducing fidelity and SNR based on the existing seismic data is a difficult problem with which all geophysical engineers need to be confronted. In this paper, taking NEB gas field in Indonesia as an example, seismic data resolution is improved using the spectral inversion technology, the distribution characteristics of structures and faults in NEB oil and gas field are better ascertained, and the transverse connection of reservoirs and the distribution regularity of sand bodies are finely described, thus having great guidance significance to next development of NEB gas field.
