Published Paper in SEG Interpretaion Journal

In 2016, a well was drilled into a Miocene reefal carbonate buildup located in the southeast of the Nam Con Son Basin offshore Vietnam. The well encountered gas in a highly porous dolomitized carbonate section. In this paper, the authors use these data to explore how the limited information within the seismic data places demands on the inversion process for producing realistic models of the subsurface that honor all the information available (seismic, rock physics, geologic, well). The paper follows the outline of a standard inversion workflow: petrophysics, rock physics, feasibility analysis, well tie and wavelets, inversion, and interpretation. Three inversion types are run: single stack inversions of near- and far-angle stacks, standard simultaneous partial angle stack inversion, and a facies-based simultaneous inversion. These three inversions highlight the strength of constraint required to produce realistic models of the carbonate and highlight the uncertainties in predicting or interpreting the critical features of the carbonate reservoir.
