Rock physics models are widely used in hydrocarbon reservoir studies. These models make it possible to simulate a reservoir more accurately and reduce the economic risk of oil and gas exploration. In the current study, two models of Self-Consistent Approximation followed by Gassmann (SCA-G) and Xu-Payne (X-P) were implemented on three wells of a carbonate reservoir in the southwest of Ira...

Understanding elastic properties of reservoir rocks is essential for seismic modeling under different saturation conditions as well lithology discrimination. Experiments on limestones are significantly less published compared to siliciclastic sedimentary rocks. The current study presents the results laboratory measurements Pannonian Basin limestone cores. research was carried out first time a h...

An analysis of the Kimura 3ST model of DNA sequence evolution is given on the basis of its continuous Lie symmetries. The rate matrix commutes with a U(1)×U(1)×U(1) phase subgroup of the group GL(4) of 4× 4 invertible complex matrices acting on a linear space spanned by the 4 nucleic acid base letters. The diagonal ‘branching operator’ representing speciation is defined, and shown to intertwine...
