.... Statement of Theory and Definitions The Kozeny-Carman equation is used widely in petroleum, chemical, and groundwater engineering. This equation relates permeability, k , to porosity, ϕ , and median grain diameter, d g . Assuming monodisperse, spherical grains, the Kozeny-Carman equation is (e.g...

.... These finer cuttings are subsequently smeared into the wellbore face by the mechanical contact of the large diameter casing with the borehole wall. The result is a very high quality, tight, thin, almost impermeable mud cake that isolates the formation from the wellbore. Evidence shows that cement binds very...

... is the increase in effective perforation length. We also confirmed previous findings that DUB perforating increases tunnel diameter, while reducing the thickness of the "crushed zone" of impaired permeability, which surrounds each tunnel. Although these processes have been mentioned in general terms previously...
