Non-Darcy fluid flow modeling in low-permeability reservoirs

Authors: V.A. Baikov, A.Ya. Davletbaev, D.S. Ivaschenko (RN-UfaNIPIneft LLC, RF, Ufa)

Key words:well testing, non-Darcy flow, low-permeability reservoirs.

The paper discusses numerical results on non-Darcy fluid flow modeling in low-permeability reservoirs. We investigate the pressure pattern behavior under a nonlinear relation between flow rate and pressure gradient. The use of non-Darcy flow modeling in pressure/rate transient field data analysis exhibits new possibilities for estimating permeability and drainage area. The results obtained show that the effective drainage area is significantly smaller than interwell distance in a development system cell. This may cause decision making for infill drilling in low-gradient areas.
