... diffusion while the late time dissolution is predominantly governed by convective mixing mechanism. In this paper, linear stability analysis of density- driven miscible flow for carbon dioxide sequestration in deep inclined saline aquifers is presented. The effect of inclination and its influence...

..., and molecular diffusion within the matrix, the production process can be difficult to model. Several authors have presented different approaches involving the complex features related to adsorption and diffusion to describe the production performance for coalbed methane wells. Various programs are now...

... diffusivity equation by modification of total gas compressibility. It is shown how the traditional definition of the material balance pseudo-time is modified for dry CBM reservoirs. With the help of these transformations, the traditional (PTA and RTA) type curves can be employed for analysis of production...

... communication between the injector and producer. In addition, it may increase the rate of diffusion of the solvent into the oil. Heat may be applied by electric heaters, by a closed steam or glycol loop, or by direct injection of steam. In the first three of four experiments described in this report, the wells...
