Abstract
In the early 90’s, Batzle and Wang (1992 ) proposed an important formulation for the calculation of seismic properties of pore fluids, which has been extensively used by the Geoscience community. Meanwhile, the Engineering community has developed different formulations, rendering special attention to the equations proposed by Dranchuk and Abou-Kassem (1975) . We analyze and compile a set of equations mainly based on Dranchuk and Abou-Kassem (1975) with variations as prescribed by Sutton and Hamman (2009) for modeling seismic properties of natural gas fluids, therefore referred as DASH formulation. We also evaluate this alternative formulation, testing it on data collected from literature. In total, 949 data points are used as reference data to evaluate DASH formulation, using Batzle and Wang (1992) equations, referred as BW formulation, for comparison. The results show that the alternative formulation outperforms the traditional Batzle and Wang formulation (BW), yielding superior data fitting and error reduction.
