The authors of paper  refer to papers [2, 3] by Dorovsky et al. as the source of governing equations of the poroelasticity model being studied in their paper. In papers [2, 3], according to the authors' opinion, the equations of motion of saturated porous media were obtained in terms of displacement velocities. It should also be noted that papers [2, 3] investigate nonlinear non-stationary problems, but did not consider linear static problems. The equations of motion in terms of displacements, considered in the paper by Amit Kumar et al.  were first introduced by Kh.Kh. Imomnazarov in paper  on the basis of equations of a model of continual filtration theory [2, 3]. The corresponding boundary value problem in terms of displacements was solved using the Galerkin vector by Kh.Kh. Imomnazarov et al. in  (published in English in 2003). Paper  does not contain references to [4, 5]. As the matter of fact the authors could perform these investigations independently. However, the analysis of the text of paper  causes one more remark.
