Figure 3. Thin-section photomicrograph images of analyzed samples: (A) W1-01 (porosity [φ] = 23.0%, permeability (k) = 8.95 md, P-wave velocity [Vp] = 3.11 km/s [10,203 ft/s]), moderately sorted oolitic and oncoidal skeletal grainstone within thin grain-rimming cement (red arrows [in color version]) and primary interparticle macropores (e.g., a); (B) W1-02 (φ = 25.7%, k = 222 md, Vp = 2.97 km/s [9744 ft/s]), moderately sorted oolitic skeletal grainstone with patchy calcite cement; (C) W1-05 (φ = 28.9%, k = 602 md, Vp = 2.26 km/s [7415 ft/s]), moderately well-sorted peloidal skeletal grainstone with primary interparticle macropores supplemented by biomolds (b); and (D) W1-07 (φ = 22.9%, k = 9.78 md, Vp = 2.84 km/s [9318 ft/s]), poorly sorted oncolitic peloidal skeletal grainstone in which the primary interparticle pore network has been solution enhanced (white arrows).
