<![CDATA[The limited resolution of 2D seismic data often limits the accuracy of subsurface interpretation. This study explores how deterministic inversion can enhance the elastic representation of low resolution intervals in Field X and contribute to more precise reservoir interpretation. By applying deterministic inversion, we aimed to improve the mapping of lithological variations throughout the interval. Petrophysical data show that the target zone contains porosity values of 11–22%, Gamma Ray readings of 10–120 API, and P-impedance values of 11022–15343, which were used for well–seismic tying and model calibration. The inversion generated an acoustic impedance model that closely aligns with the log trends, showing a coherence error of just 6.23% within the target interval. Domains with increased permeability and diminished GR readings are distinguished as faint impedance irregularities, whereas more consolidated phases are marked by heightened impedance. The ensuing impedance reaction encapsulates geologically significant mid range lithological fluctuations, although constraints imposed by seismic resolution persist in diminishing the precision of stratigraphic demarcations. In general, the findings demonstrate that when deterministic inversion is meticulously fine-tuned with petrophysical datasets, it can yield a consistent and measurable impedance framework, even in areas with constrained seismic fidelity, thereby facilitating more dependable reservoir analysis.]]>
