Preview Abstract
In routine core analysis, porosity and permeability, both relative and absolute, are
measured permeability, both relative and absolute, are measured on rock samples
which are not under net overburden (confining) pressure. Using these data to
predict reservoir performance or estimate reserves can lead to serious errors since
all reservoirs are under net overburden pressure.
Data collected from constant rate, dynamic displacement experiments were utilized
to study the effect of net overburden pressure on porosity and absolute and
relative permeabilities. These experiments were conducted on small, consolidated
rock samples under net overburden pressures up to 41.37 MPa (6000 psi) and
room temperature. The pore pressure was maintained atmospheric. pressure was
maintained atmospheric. Examination of the data shows a decrease in porosity
and permeability with increase in overburden porosity and permeability with
