摘要： A method for estimating an amount of hydrocarbon in an earth formation having a kerogen includes determining a pore size in the kerogen at or below which capillary condensation will occur, the determining being performed using a processor. The method also includes calculating an amount of hydrocarbon liquid condensate in pores of the kerogen based on capillary condensation using the determined pore size, the calculating being performed using the processor. The method further includes estimating the amount of hydrocarbon in the earth formation using the calculated amount of hydrocarbon liquid condensate, the estimating being performed using the processor.

摘要： A method includes acquiring formation fluid sample information including pressure, volume, and temperature. Monotonic formation fluid information is extracted from the formation fluid sample information and a pressure, volume, temperature information set is constructed. A curvature sequence is estimated using a first partial derivative and a second partial derivative of pressure with respect to volume. A first maxima is estimated from the curvature sequence, and the formation fluid property is estimated using the estimated first maxima. A method may include a volume acceleration sequence estimated using a first partial derivative and a second partial derivative of the volume with respect to pressure. A first maxima is estimated from the volume acceleration sequence, and the formation fluid property is estimated at least in part by using the estimated first maxima. A method may include establishing a first linear regression model and predicting a confidence interval.
