Carbonate reservoirs exhibit complex pore structure, which significantly affects the elastic properties and seismic response, as well prediction of physical parameters. As one main factors impacting fluid prediction, structure parameter directly involves in few inversion methods. In order to predict inversion, a novel quantitative reflection coefficient formula is proposed, that integrate Russe...

The slip effect on hydromagnetic rotating flow of viscous fluid through a porous space is investigated. The fluid is electrically conducting with the consideration of Hall current. The entire system rotates about the axis normal to a porous plate of uniform suction or injection with uniform angular velocity. The closed form solution is obtained using Laplace transform technique. The analytical ...

In this paper, the unsteady flow of non-Newtonian fluid through a porous medium when an external magnetic field is applied is investigated. The non linear equation of motion is transformed to a similarity differential equation which is solved using the method of successive approximations. The rheological effects are shown and discussed on the velocity profile in terms of rheological parameter o...

Einstein field equations under spherically symmetric space-times are considered here in connection to dark energy investigation. A set of solutions are obtained for a kinematical Λ model, viz., Λ ∼ (ȧ/a) without assuming any a priori value for the curvature constant and the equation of state parameter ω. Some interesting results, such as the nature of cosmic density Ω and deceleration parameter...
