... is a sensitivity analysis on the three different fracture propagation models PKN-C, KGD-C and the P3D-C. This section focuses on different factors that affect fracture geometry, including fluid rheology, injection rates, fluid leak-off and fracture height. The fracture dimensions displayed are those calculated...

... results and experimental data. The simulation results showed that by increasing the solvent slug size, oil recovery increases before breakthrough, but the trend declines after this time. Increasing water injection rate in WAS and SWAS schemes improved the displacement efficiency. Besides, all above, some...

Performance of a water-alternating-gas (WAG) process is largely affected not only by the injection parameters including water-gas ratio, injection rate and cycle period, but also...

... and resuming water injection. Experiments are carried out at temperatures of 30 and 35 °C, and water injection rates between 1 and 50 feet per day, to recover heavy oils with viscosities of 1500 to 2000 cP. Carbonated water used in these experiments is prepared by dissolving CO 2 in 1% wt. NaCl brine over 48...

.... Simulations were run at a constant subcool (25°C) in order to optimize pressure and solvent injection rate. A similar set of simulations was run for the steam-pentane hybrid process, to optimize the process in terms of pressure and steam rate. All simulations were compared in terms of an objective function...

The main part of this simulator is the BHP calculation routines. This part calculates BHP based on the two phase flow modeled procedures. The BHP...

... is we disturb the prevailing quasi-equilibrium in the reservoir via cyclically varying injection rates and by imposing perturbations in pressure and/or saturations, thereby causing transient changes to the fluid and flow distributions. Our hypothesis is based on the following postulates: a. High rates...

When the CO2 stream contains impurities such as N2 or methane, the storage capacity of the reservoir decreases proportionally to the impure stream s compressibility factor and its...

... The Johnson-Bossler-Nauman (JBN) Method[6] for calculating relative permeabilities from unsteady-state displacement data was used. The JBN Method is used to calculate the relative permeabilities of the core as a function of the effluent or terminal fluid saturation for displacements at constant injection rate...

We evaluated half unit of a seven spot pattern by building an unstructured grid, which provide more flexibility in terms of geometry. The results indicated that injection rates higher than 4000 B/D combined...

..., effect of injection rate from 0.3 up to 15.4 meter per day was tested and it was observed that slower injection of polymer solutions resulted in higher oil recovery. It is believed that the results of this study will help develop effective methods for implementing polymer flooding in heavy oil fields...

..., the heat losses from the model are large, and a steam injection rate higher than a threshold value, which is between 2 cc/min. and 5 cc/min. was needed to promote expansion of a steam chamber.

The CO2 temperature has been successfully predicted in order to keep CO2 in supercritical condition from the surface to the bottom for various CO2 injection rates and electric heater power. Finally, Injected CO2 is expected to be supercritical over 12ton/day...
