..., and an integro-differential solution coupled to a Green's function (GF) is used to represent the source/sink term. A set of pressure and permeability data from geomechanical literature is used and transformed into effective stress through Biot's equation. The effects of overburden, source/sink term, deviation...

... ABSTRACT The isotropic homogenous assumption in the conventional Geertsma model is often contradicted by reality because the rock properties in the overburden are typically anisotropic and often can be quite different from the reservoir. Thus, we present an analytical solution that extends...

... show that fast injection prevents significant compaction in the reservoir. Besides, the calculated shear deformation in the overburden is utilised to study wellbore stability during storage. The results indicate that the accurate characterisation of the porosity distribution in the reservoir as well...

We use two-dimensional plane-strain, finite element code to investigate the mechanics of growth of a shale-cored fold in the South Caspian Sea Basin, where c.10 km of sediment was deposited in the last 6 Myr. The overburden and syn...
