Advanced core analysis includes measurements on the matrix properties of the rock. Matrix properties are important even in fractured wells since it is these properties which determine the rate of gas flow into the fractures. Cores are being tested from the fluvial, coastal, and paludal zones of the Mesaverde. At least two cores from each of these zones from all three wells will be analyzed. Properties measured include permeability as a function of confining pressure over the range of 500 to 5000 psi. A minimum of two Klinkenberg permeabilities are being determined from at least five data points. Interpretation includes …

Description
Advanced core analysis includes measurements on the matrix properties of the rock. Matrix properties are important even in fractured wells since it is these properties which determine the rate of gas flow into the fractures. Cores are being tested from the fluvial, coastal, and paludal zones of the Mesaverde. At least two cores from each of these zones from all three wells will be analyzed. Properties measured include permeability as a function of confining pressure over the range of 500 to 5000 psi. A minimum of two Klinkenberg permeabilities are being determined from at least five data points. Interpretation includes estimates of pore size from gas slippage. Water adsorption and desorption isotherms will be determined for selected samples with data points being obtained at the following relative humidities: 0, 20, 40, 60, 75, 90, 92, 95 and 98. Porosity measurements from both thin section examination and volumetric measurements are being made. These results will be compared with the porosities of the cored internals determined from logs.
