Table 3 Mineral weight percents used in geochemical simulations.

From: Experimental Study of Cement - Sandstone/Shale - Brine - CO2Interactions

Phase Sandstone Shale
Albite 1.5% 2%
Chlorite 6% 30%
Dolomite 0.5% 0.75%
Illite 1.5% 44%
Kaolinite 4% 4%
Quartz 86% 20%
Siderite 1.5% 0.75%
  1. (Ankerite was modeled as a 25 - 75 siderite-dolomite mixture for sandstone and a 50 - 50 siderite-dolomite mixture for the shale.)
