Pattern geometry plays a major role in determining oil recovery during waterflooding
and enhanced oil recovery operations. Although simulation is an important tool for
design and evaluation, the first step often involves rough calculations based upon areal
sweep efficiencies of displacements in homogeneous, two-dimensional, scaled, physical
models. These results are available as a function of the displacement pattern and the
mobility ratio M.
In this research I studied the effect of mobility ratios on five-spot and staggered
waterflood patterns behavior for areal (2D) displacement in a reservoir that is
homogeneous and isotropic containing no initial gas saturation. Simulation was
performed using Eclipse 100 simulator.
Simulation results are presented as graphs of areal sweep efficiency at breakthrough
versus Craig mobility ratio for various staggered line drive aspect ratios.
The main results of the study are presented in the form of a graph of areal sweep
efficiency at breakthrough as a function of staggered line drive aspect ratio. This should
enable engineers to utilize the results in a convenient manner.
