Abstract
Understanding the flow characteristics in laminar and turbulent flow regime is
important for different aspects of reservoir and production engineering. One of
the most important parameters in fluid flow is the permeability of the porous
media. It is common practice in the industry to use Darcy and Forchheimers
equations for characterising the fluid flow in the porous media at laminar and
turbulent regimes, respectively.
Core flooding experiments were performed with 1.5-inch diameter size core
samples from limestone and sandstone formations. The permeability of the
samples was measured in the laminar regime at basis flow rate. Then, the flow
rate was increased in different steps and permeability was measured,
accordingly. The plot of permeability versus flow rate was used to track the
evolution of the flow regimes in the core porous media.
There are different challenges to monitor the transition between laminar and
turbulent regime through core flooding experiments. These challenges are
discussed in this paper through both literature review and also experimental
results. The results indicated that the core sample preparation, experiment control
parameters and also test profiles are important aspects when measuring
permeability in the lab.
Keywords: permeability, laminar, turbulent, Darcy law, pressure drop.
