Correlation of petrophysical properties across multiple wells in the Nubia Formation, presented through a cross-section (A–B) covering wells GS323-3, GS323-1, GS323-4 A, and GS323-2 A. The figure displays various log tracks, including shale volume (“track 1”), porosities (“track 2”), where the blue curve represents total porosity and the red curve represents effective porosity, and permeability (“track 3”). Fluid saturation (“track 4”) is shown with blue shading for water saturation and green shading for hydrocarbon saturation. Additionally, rock flag indicators (“track 5”), reservoir flag indicators (“track 6”), and net pay flag indicators (“track 7”) are highlighted to assess reservoir quality. The yellow shading emphasizes key reservoir zones across the wells, illustrating lateral variations in lithology and fluid distribution. This cross-section provides insights into the continuity and heterogeneity of the Nubia Formation, aiding in hydrocarbon evaluation and reservoir characterization.
