1. A method for estimating a formation fluid property comprising: acquiring formation fluid information, the formation fluid information including pressure and volume; extracting monotonic formation fluid information from the formation fluid information; constructing an information set from the monotonic formation fluid information; estimating a first partial derivative and a second partial derivative of the pressure with respect to the volume from the information set; estimating a first maxima from a curvature sequence; and estimating the formation fluid property at least in part by using the estimated first maxima.
