At JACZ, integrated well log analysis is a cornerstone of our formation evaluation consulting services. We approach data from a multidisciplinary perspective—sedimentological, stratigraphic, petrophysical, and rock physics—to construct a coherent and technically robust subsurface model. This approach not only provides the reference framework for initial reservoir characterization in exploration stages but also ensures consistency with seismic responses, facilitating integration with geological, static, and dynamic models. Our methodology enables precise assessment of reservoir unit quality and continuity, optimizes flow simulation, and supports strategic decision-making in field development and operations.
