In this paper, the unsteady flow of two immiscible fluids with heat transfer is studied numerically with a modified cubic B-spine Differential Quadrature Method. Generalized Couette two immiscible dusty (fluid-particle suspension) and pure (Newtonian) are considered through rigid horizontal channels for three separate scenarios: first non-porous plates heat transfer, second porous uniform s...

This study focuses on the derivation of a semi-analytical approach for the evaluation of surface uplift and caprock deflection induced by underground injection of CO2. The adopted methodology includes the development of amathematical model that incorporates the deformable behaviour of the storage reservoir and the flow of two immiscible fluids (CO2 and brine) within the aquifer while the surfac...

This study focuses on a specific problem related to the caprock deformation induced by the injection of CO2 at depth. The adopted methodology includes the development of a mathematical model that incorporates the deformable behaviour of storage media and the flow of two immiscible fluids (CO2 and water) within the aquifers while the surface rock or caprock layer is modelled as a thin plate. Gov...

The injection of carbon dioxide (CO2) in deep, unmineable coalbeds is a very attractive option for geologic CO2 storage: the CO2 is stored and at the same time the recovery of coalbed methane (CBM) is enhanced. The revenue of methane (CH4) production can offset the expenditures of the storage operation. Coalbeds form complex gas reservoirs characterized by their dual porosity: they contain both...

As oil and gas reserves become depleted, producers are increasingly driven to process difficult or unconventional petrochemical fuel sources to sell to the market in order to meet rising demand. One such source is the production of sour gas wells that contain high levels of mercaptan (thiol) species. In sour gas processing applications, a waste acid gas stream (ie. a stream containing high conc...

A steady state analysis method was developed for gas networks with distributed injection of alternative gas. A low pressure gas network was used to validate the method. Case studies were carried out with centralized and decentralized injection of hydrogen and upgraded biogas. Results show the impact of utilizing a diversity of gas supply sources on pressure distribution and gas quality in the n...

A unique normalized radial pressure profile characterizes the bed of a gas-solid vortex reactor over a range of particle densities and sizes, solid capacities, and gas flow rates: 950-1240 kg/m3, 1-2 mm, 2 kg to maximum solids capacity, and 0.4-0.8 Nm3/s (corresponding to gas injection velocities of 55-110 m/s), respectively. The combined momentum conservation equations of both gas and solid ph...

Condensate banking around wellbores can significantly shorten the production from gas-condensate reservoirs. Several approaches to mitigate this issue have been proposed in literature, among which gas injection comes out with promising results. This method’s efficiency has largely investigated at core and field scales, but underlying flow phenomena taking place pore-scale are still poorly under...
