Figure 17.
Graph showing the effect of clay content (by weight percent) on total porosity, effective porosity, and ineffective porosity (clay microporosity) for Cypress Sandstone of reservoir quality. Data are from the John O. Coen 120 well (API 121592608300, Section 4 , T3N, R9E) and the C. T. Montgomery B-34 well (API 121592606400, Section 3 , T3N, 93E). The clay content by weight percent was obtained by x-ray diffraction analysis.
