New techniques for estimating properties of saturated reservoirs, using readily-available rate decline data

The sub-routine has been applied to two reservoir models and was found to yield excellent estimates of P¯ and So¯ data, exhibiting good agreement with P¯ and So¯ data resulting from simulating the reservoirs. Furthermore, the sub-routine-generated P¯ and So¯ data that have been used in implementing the properties estimation techniques, and the results have compared well both with the results of the techniques׳ implementation using simulator׳s P¯ and So¯ data, and with the true values of these properties.
