The vertical and horizontal postglacial rebound is detected by measuring site velocities and length rates of baselines respectively using data from space geodetic measurement of VLBI. The comparison and correlation analysis between space geodetic results and predictions of postglacial rebound from the geophysical model ICE-4G is shown. And the system error between space geodetic results and ICE-4G predictions is also discussed.

A set of quadruply coupled equations (fluid flow, convection-diffusion, energy conservation and mechanical equilibrium) with a number of cross-couplings and coupled constitutive relations is formulated to quantify the multi-physics of oil displacement by CO2 injection, implemented into and solved by using FEMLAB. FEMLAB is the first engineering tool that performs equation-based multi-physics modeling in an interactive environment. With FEMLAB, the coupled multi-physics model can be solved simultaneously. The applicability of this model has been demonstrated through an example of simulations for a two-dimensional reservoir of size 1000 m×1000 m with one injection and one production wells. Model results illustrate the significant importance of the cross-couplings between individual (thermal, hydrological, chemical and mechanical) physics.
