ELEVATING 3D RESERVOIR MAPPING WITH THE NEW FLEXIBLE INVERSION DATA FORMAT
View through CrossRef
Advances in ultradeep azimuthal resistivity (UDAR) generate dense, multidimensional inversion volumes that exceed the capabilities of legacy exchange formats. This paper presents the Advanced Borehole eXchange (ABX) format as a flexible, meta-data rich solution for preserving UDAR inversion outputs and associated Depth of Detection (DOD) geometries. UDAR measurements were inverted to produce dense resistivity volumes, exported in ABX, and visualized in reservoir navigation software to enable boundary rendering, DOD visualization, and resistivity-based decimation. Results show that ABX preserves native inversion fidelity, clarifies thin beds and lateral discontinuities as coherent 3D features, and provides explicit sensitivity context that reduces interpretation ambiguity. The integration of DOD geometries provides explicit sensitivity context that reduces interpretation ambiguity. Targeted decimation by reservoir resistivity produces cleaner, faster renderings that emphasize lateral continuity. Continuous ABX export shortened interpretation cycles and supported more decisive steering decisions, demonstrating ABX’s practical value for high-fidelity, operational reservoir mapping.
